然后电磁铁23断电，电磁铁23不具备磁力释放发电机托架3，发电机托架3沿导向轮33向下做近似自由落体运动，至发电机托架3砸在承重板7上的瞬间，这时外界接收主机接收压力传感器31的瞬间压力；Then the electromagnet 23 is powered off, and the electromagnet 23 has no magnetic force to release the generator bracket 3. The generator bracket 3 moves downward along the guide wheel 33 to perform a nearly free fall motion until the generator bracket 3 hits the load-bearing plate 7. At this time, the host receives the instantaneous pressure of the pressure sensor 31.
最后，设传感器的瞬间压力为F，发电机受到的冲击力为F’，发电机托架3重力G1，发电机重力为G2，得出发电机受到的冲击力F’=F * (G1/G1+G2)，检测发电机的受损情况，检测发电机的极限受力和抗摔高度。Finally, assuming that the instantaneous pressure of the sensor is F, the impact force on the generator is F’, the gravity of the generator bracket 3 is G1, and the gravity of the generator is G2, the impact force on the generator is F’=F * (G1/G1+G2), which can detect the damage of the generator and detect the maximum force and drop resistance height of the generator.
