[0026] The silicone shell (1) forms a closed cavity, and a metal support plate (2) is fixedly arranged on the upper side and the lower side of the silicone shell (1) respectively;

[0027] The first multi-gear generating head (3) is fixedly arranged on the metal support plate on the upper side of the interior of the silicone shell (1), and the second multi-gear generating head (4) is fixedly arranged on the metal support plate (2) on the lower side of the interior of the silicone shell (1); the first multi-gear generating head (1) and the second multi-gear generating head (1) comprise a plurality of hammer heads (31); the first multi-gear generating head (3) and the second multi-gear generating head (4) are used to knock on the metal support plate (2) on the upper side and the metal support plate (2) on the lower side of the interior of the silicone shell (1) respectively; the size of the hammer head (31) of each gear of the first multi-gear generating head (3) and the second multi-gear generating head (4) and the knocking speed of the hammer head (31), as well as the material parameters of the silicone shell (1) are obtained by performing finite element analysis on the human body simulation device and the vibration device;

[0029] The controller (5) is connected to the motor (32).

[0030] Specifically, through finite element simulation, appropriate silicone parameters and metal support plate parameters are selected, and the structure itself is damped to generate a heart rate signal in the form of a sine wave superposition, which is closer to the actual situation than the existing signal. The dual motors drive the generator head to knock on the metal support plate in both directions, and by adjusting the amplitude relationship on both sides, a bidirectional heartbeat signal is emitted.

[0031] The specific finite element simulation includes the following steps:

[0032] Step S1: Establishing a geometric model of a device for simulating body movement induced by heart rate, and establishing geometric models of a large number of first multi-gear generating heads and second multi-gear generating heads of different sizes; the generating heads are used to knock on the two sides of the metal support plate of the silicone body;

[0033] Step S2: predetermine the material parameters of the heart rate-induced body movement simulation device and the vibration device, and construct a silicone body finite element analysis model and a generating head finite element analysis model according to the geometric model of the heart rate-induced body movement simulation device and the geometric models of the generating heads of different sizes;

[0034] Step S3: pre-acquire actual heart rate signals of a plurality of real human bodies in different health states; for any actual heart rate signal, execute steps S4 to S5;

[0036] Step S5: Determine the similarity between the simulated heart rate signal and the actual heart rate signal. If the similarity is lower than the set value, replace the finite element model of the generating head with a different size or replace the material parameters of the simulation device for heart rate-induced body movement and the vibration device. Repeat steps S4-S5 until the similarity between the output simulated heart rate signal and the actual heart rate signal is greater than the set value. Output the size information of the generating head that generates the similarity between the simulated heart rate signal and the actual heart rate signal greater than the set value, which is recorded as the final generating head size information; and output the material parameters of the human body simulation device and the vibration device.
