It is transferred to Step 3: acceleration transducer receives the acceleration signal of the first fixed plate displacement and is converted into electric signal
Data processor, the electric signal converted via data processor are transferred to computer processor and are calculated, and obtain the first fixed plate
Current value needed for the size of suffered impact force and counteracting impact force；
Step 4: computer processor calculates gained current value according to step 3 adjusts rheostatic resistance value, and by adjusting variable resistance
The first coil and the current value of the second coil that the adjusting of device resistance value is connected with rheostat, the electricity in first coil and the second coil
When stream is more than the current value of step 3 calculating gained, the magnetic force generated between first coil and the second coil is more than first
The force directions of external forces suffered by fixed plate, magnetic force and external forces on the contrary, the first fixed plate by
Resultant force with external forces on the contrary, the speed of external force displacement at this time declines under the first fixed plate force action, until external force
The speed of displacement is zero；
Step 5: the acceleration direction of the first fixed plate is identical with the resultant direction that the first fixed plate is subject to, the second fixed plate exists
The first fixed plate is pushed to move upwards, and acceleration is less and less under the action of first coil and the second coil magnetic field power, until
Into the limitation range of range sensor, range sensor disconnects the connection with acceleration transducer, first coil and the second line
Current value in circle is zero, and magnetic force disappears, and remaining external forces are by the first spring in the first vibration absorber and the
The elastic force of second spring in two vibration absorbers is offset jointly.
