Abstract
A collision simulation test apparatus including a table to which a test piece is to be attached, the table being movable in a predetermined direction, a toothed belt for transmitting power to drive the table, a drive module capable of driving the toothed belt, and a control part capable of controlling the drive module. The control part is capable of controlling the drive module to generate an impact to be applied to the test piece, and the impact generated by the drive module is transmitted to the table by the toothed belt.
Claims17
A test apparatus comprising:
- a table to which a test piece is to be attached and configured to be movable in a predetermined direction;
- a drive module configured to generate power for driving the table, the drive module including an electric motor;
- a toothed belt configured to transmit the power to the table;
- and
- a controller configured to control the drive module,
- wherein:
- a ratio of maximum torque to inertia moment of the electric motor is equal to or more than 1000,
- the controller is configured to control the drive module to generate an impact to be applied to the test piece, and
- the test apparatus is configured to be capable of generating the impact of an acceleration exceeding 20G with the drive module and transmitting the impact to the table with the toothed belt.
