Mujer sentada en una silla con dolor de espalda sobre.. The tether system allows this heave plate 102 to be deployed deeper than those that are rigidly fixed to the buoy 106, which increases the effect of the heave damping. This additional freedom of motion limits the heave forces that can be generated when compared to a fixed reference. This configuration might look similar to that depicted in Figure 2. In this figure, the plate entraps a significantly larger volume of water when the buoy 106 is pulling it towards the surface (the added mass of the displaced water with the plate is very large), but the plate 202 can move more easily downward as the tension is decreased (the added mass of the displaced water with the plate is relatively small in the downward direction). The flexible tethers allow for the surface float and the heave plate to move out of sequence during the various modes of motion that a surface float and heave plate would be subjected to.

In some embodiments, generator units are disposed on the surface float or within the surface float. In some preferred embodiments of the invention, the added mass of the heave plate may be over 2 times, and preferably over 5 times that of at least one surface float. In other embodiments, the added mass of the heave plate may be over 5 times that of at least one surface float, and simultaneously a heave plate may have moment of inertia in at least one mode of motion that is over 5 times that of at least one surface float. Fig. 1 depicts an embodiment of a device 100 for generating electricity for use with a heave plate 102. In one embodiment, the heave plate 102 is a simple plate with taut tether(s) 104 extending upwards that connect to a surface float 106, floating in water 108. The plate 102 may be either a solid surface, or may contain perforations 112 or be perforated such that water 108 can flow through it, albeit it in a restricted manner.

Fig. 7 depicts a schematic diagram of one embodiment of a surface float and a heave plate tethered by flexible tethers. An aspect of this mode of capture involves setting the ratio of moment of inertia ratio between the heave plate and surface float as shown in Fig. Remedio natural para el dolor de rodilla . Fig. 6 depicts one embodiment of a resulting RAO, with the top plot showing overall power response against frequency and the bottom plot showing heave and pitch power response. Embodiments described herein relate to a wave energy converter system with a heave plate. Embodiments of a method for converting wave energy are described. Some embodiments of the present invention comprise a method for generating electricity, the method comprising: utilizing the motion of a body of water, including wave motion, to cause changes in the strain of one or more magnetostrictive elements deployed with one end mechanically coupled to a buoyant device (or buoy) and the other end mechanically coupled to a heave plate; and using a corresponding change in magnetic flux density in the magnetostrictive elements to generate an electric voltage and/or electric current in one or more electrically conductive coils or circuits that are in the vicinity of the magnetostrictive elements, wherein there is no substantial relative motion between the one or more magnetostrictive elements and the one or more electrically conductive coils or circuits.

Some embodiments of the present invention comprise a device for generating electricity, the device comprising: at least one magnetostrictive element, at least one buoyant device (or buoy), at least one heave plate and when deployed in a body of water, the interaction of waves with at least one buoy causes changes in the strain of one or more magnetostrictive elements; and one or more electrically conductive coils or circuits within the vicinity of one or more of the magnetostrictive elements, wherein a corresponding change in magnetic flux density in the one or more magnetostrictive elements generates an electric voltage and/or electric current in the one or more electrically conductive coils or circuits, wherein there is no substantial relative motion between the one or more magnetostrictive elements and the one or more electrically conductive coils or circuits. Some embodiments comprise a device for generating electricity, wherein the device comprises: a buoy deployed in a body of water; a magnetostrictive element mechanically coupled to at least one buoy and at least one heave plate, wherein the motion of the body of water, including wave motion, causes motion of the buoy, which in turn causes changes in the strain of the magnetostrictive element; and an electrically conductive coil or circuit within the vicinity of the magnetostrictive element, wherein a corresponding change in magnetic flux density in the magnetostrictive element generates an electric voltage and/or electric current in the electrically conductive coil or circuit, wherein there is no substantial relative motion between the one or more magnetostrictive elements and the one or more electrically conductive coils or circuits.

Fig. 2 depicts one embodiment of a device 100 for generating electricity with an asymmetric heave plate 202. In one embodiment, a plate 202 is more streamlined in one direction, i.e., the coefficient of drag is lower when the plate motion is in one direction. Fig. 4 depicts one embodiment of a device 100 for generating electricity with a slack safety line 122 between the heave plate 102 and the buoy 106. In some embodiments, the configuration may also be modified to accommodate any number of PTO modules, for example, a single large PTO module 1 10, as shown in Figure 4. In this case, there are multiple tethers 104 from the edge of both the heave plate 102 and the buoy 106 that merge into a single line 120 before attaching to the PTO 1 10. This enhances the stability of both the plate 102 and buoy 106 by constraining some of their respective pitch and roll motions.

LMady: Psoríase e Acupuntura In one embodiment, the perforations 1 12 that are mentioned in the description of the symmetric plate 102 could also be tailored to be asymmetric 202, such that the perforations 112 themselves restrict the flow of water 108 in one direction more than the other. The heave plate 102 can be further tailored to help avoid such events. Some embodiments are able to increase the static mass of the heave plate so that slack events cannot occur; however some modeling indicates that this may result in an unacceptably heavy structure. In some embodiments, the heave plate has a natural period that is at least 1.5 times higher than the period of the most prevalent wave at the site in which the device is deployed. The generators are deployed within a surface float are mechanically coupled to a heave plate by at least one flexible tether. However, by establishing the mass properties of the heave plate and surface float accordingly, the wave induced pitch motion may be used to generate significant alternating forces in the tethers.

As an alternative, the geometry of the heave plate can be varied to provide increased hydrodynamic mass properties in an asymmetric form that would allow a physically lighter structure to provide the same reaction forces as compared to a much heavier symmetrical structure. An additional observed effect of using a non-rigidly mounted heave plate is that in large sea states there is a tendency for slack events to occur in the tethers. In the above description, buoyant structure, buoyant device, and surface float are sometimes used interchangeably. In some embodiments, the heave plate is disposed at a depth greater than 10 meters below the water surface. Dolor de cabeza por contractura muscular . The first level of resistance is higher than the second level of resistance. The heave plate has an asymmetric geometry to facilitate a first level of resistance to movement in an upward direction and a second level of resistance in a downward direction.

The primary areas of interest for offshore platforms were numerical simulation and experimental modeling to investigate the effects of a variety of parameters on heave plate performance. Conventional uses of heave plates typically focus largely on heave plates for offshore spar platforms used in the oil and gas industry. Some design parameters and/or approaches from conventional heave plate implementations, including some aspects of methodology and modeling techniques, may be useful in the design of heave plates for embodiments of magnetostrictive wave energy harvesters. This is different from conventional spar buoy implementations because the taut-moored implementation relies on the damped motion of the heave plate to create tension changes in the tether (not on the large relative motions necessary for other systems to create energy).

This increase lowers the natural frequency of the system, and essentially creates a high-pass filter that will respond to very low frequency waves (i.e., tidal waves), but not significantly to the regular ocean waves caused by wind. In some embodiments, the heave plate may have moment of inertia in at least one mode of motion that is over 2 times that of at least one surface float. Fig. 5 depicts one embodiment of an optimization surface showing a maximum balance of moment of inertia and mass ratios between a heave plate and a surface float that will maximize energy captured within a system. 5 with the resulting RAO shown in Fig. Sarpullido y dolor muscular . Fig. 1 depicts an embodiment of a device for generating electricity for use with a heave plate.

Changing the ratio of the moment of inertias of the heave plate and surface float affect the energy captured by a device as the modes of motion of the surface float and the heave plate with create oscillating. As the tension is reestablished after such a “slack event”, a snap load will be applied to the system with potentially catastrophic consequences. In some embodiments, the elements are not magnetostrictive elements. This also occurs by changing the mass ratio between the surface float and the heave plate. These parameters include plate thickness to width ratio, shape of plate edge, plate depth, oscillation frequency, effects of Keulegan-Carpenter number, hole size, and perforation ratio.
