Stage property table is optimized.
9. train occupant's secondary collision test method according to claim 7 or 8 based on Electromagnetic Control, feature exist
In, further includes:
It is accelerating region by division of period orbit, slides area and trial zone；
Train accelerates in accelerating region；
It slides in area when Train Approaching uniform motion, trial zone is entered when acceleration is zero；
Simulating crew secondary collision scene in trial zone, according to the third acceleration transducer with dummy, pressure sensor, position
Displacement sensor obtains dummy's damage situations in secondary collision, sets so that user optimizes structure in compartment in secondary collision
Meter.
