Collision simulation test apparatus and impact test apparatus

A test apparatus comprising:

• a table to which a test piece is to be attached and configured to move linearly in a predetermined direction;
• two or more drive modules configured to generate power for driving the table;
• a belt mechanism configured to transmit the power generated by the two or more drive modules;
• and
• a controller configured to control the two or more drive modules,
• wherein:
• the belt mechanism includes one or more pairs of toothed belts arranged in parallel with each other, each of the toothed belts being provided with one or more of the drive modules,
• each of the drive modules includes:
• a drive pulley around which one of the pair of toothed belts is wound;
• and
• an electric motor of which a rotation shaft is connected to the drive pulley and having an inertia moment that enables generation of accelerations equivalent to impacts generated by collisions, and
• the controller is configured to synchronously control each of the electric motors of the two or more drive modules according to an acceleration waveform that is set based on an impact generated by a collision to be simulated to apply the impact generated by a collision to be simulated to the test piece.
