This invention relates to a whole body vibrator platform which is attachable to a treadmill. The treadmill belt provides the power to move the platform, translating the horizontal, linear, belt movement into vertical oscillations through one or more eccentrically mounted rollers which support the platform. A person standing on the vibrator platform experiences a vertical vibration at frequencies established by the linear velocity of the treadmill belt.

An electrically-powered linear motor for a whole body vibration (WBV) machin e is disclosed for producing and imparting vibrations to a platform for supporting a user. The linear motor comprises one or more pairs of generally aligned coil s for producing electromagnetic responses in one or more magnets, each disposed generally intermediate a pair of coils. Current is intermittently passed through the coils to produce vibrations within a desirable frequency range in the platform.

An object of the present invention is to execute an optimum control of vibrations due to a driver's operation of an accelerator pedal, steering wheel and brake pedal. The operation instructions are inputted into a vibration calculating means (kinetic model) comprising a vehicle body model, suspension model and tire model. Conventional kinetic model controlled the suspension in order to suppress the vehicle body vibration. However, in the kinetic model of the present invention, the tire vibration due to a change in the engine output is first absorbed by the suspension, whereby a residual vibration which was not be absorbed yet by the suspension is transferred to the vehicle body. The operation inputs are compensated by the three feed-back loops between the outputs of the above-mentioned three portions and input of the tire portion, giving the highest priority on the vehicle body model.

The invention discloses a tilting-type dual-motor human vibration generation device. A pair of linear motors are installed on a base. Each linear motor has a stator locked at the base and a moveable set, and the linear motors linearly move the moveable set driven by a current source. The current source is electrically coupled to the linear motors for supplying alternating current to the linear motors. A controller is in communication with the current source for controlling information at a selected phase relationship between the linear motors. A platform is installed at the base and moves by driving the moveable set connected with the linear motors using an elastic support compound. In a tilting mode of the platform movement mode, the tilting of the platform in the phase operation is caused by the linear motors. An elastic support form between the moveable set and the platform, such as a plastic compound connected with the platform and the moveable set of the linear motors, accommodates the tilting of the platform by the elastic ability of the plastic compound.

A whole body vibration apparatus 100 has a motion inducing device 110 positioned other than under the vibrating platform 194 so that a vibrating platform 194 may be located close to the ground. Dual rocker shafts 178 journalled to reciprocate in a rotationally reciprocating motion, convert the linear motion of the rear-positioned motion inducing device 110 to vertical motion of the vibrating platform 194. A coupling mechanism constituted by a linkage 172, 174, 178 connects the motion inducing device 110 to the vibrating platform 194. The linkage employs deformable couplings 172, 174 and frictionless bearings to reduce unwanted rattle and wear and to remove the need for maintenance. A compensating device 140 adjusts for the weight of the user so that the motion inducing device 110 has all its useful output employed to vibrate the platform 194 as opposed to supporting the user's weight. In addition to altering frequency and amplitude, a method for user selection of different waveforms is provided to achieve a variety of treatment benefits.

The present invention provides a three-dimensional vibration training method for animals and a method for selecting frequency parameters, comprising the following steps: Step 1: preparing animals for testing, constructing a test and testing system; Step 2: sweeping and vibrating the animals on a three-dimensional vibration table, The animal without vital signs is subjected to frequency sweep vibration again; while the animal is subjected to two frequency sweep vibrations, two three-direction acceleration sensors are used to measure the acceleration of the animal and the workbench in the vertical, horizontal left and right, and horizontal front and rear directions respectively. Signal; step 3: the acceleration signal in step 2 is transmitted to a computer and processed to determine the range of the natural frequency of the animal's body. Utilize the method that the present invention proposes, can accurately obtain the natural frequency of test animal along three directions of vertical, horizontal front and back and horizontal left and right, and designed 7 kinds of three-dimensional vibration training patterns, this is the whole body vibration training test of animals and even people provided the basis for the design.

The invention relates to a whole-body vibration training device capable of linearly changing the vibration amplitude. Its composition at least includes a base, a swing connecting rod group and a driving mechanism. The swing connecting rod group is assembled on the base, and it is provided with a Driving mechanism, and the driving mechanism can drive the connecting rod formed by several swinging connecting rods to move, through the drive of the motor, an eccentric transmission shaft drives the swinging connecting rod group to generate linear vibration during the swinging process, and cooperates with the speed of the motor so that The upper support frame produces up and down displacements of various frequency vibrations; in addition, an adjustment device can be installed between the swing link group and the base, which can change the fulcrum position of a swing link group, thereby changing the swing range of the swing link group According to this, the swing link group can be driven by the driving mechanism and its vibration amplitude can be changed linearly to achieve the effect of whole body vibration, and produce many functions such as stimulating organs, improving muscle strength, and promoting blood circulation. The whole is innovative and practical sex.

An upper body attachment, which may be used with a piece of exercising, stretching, or massaging equipment that incorporates whole body vibration (WBV) technology, provides a user with a way to apply WBV technology to the upper body. The attachment may include a pair of uprights and a crossbar to which a variety of types of handles may be slidably attached. The attachment may have a base that both supports the uprights and connects the uprights with the equipment incorporating the WBV technology. Accordingly, the attachment transfers vibrations from the vibrating equipment to the handles that a user grips. Several exemplary WBV upper body exercises that the attachment facilitates include push-ups, pull-ups, and dips.
