3 Terms and Definitions

The following terms and definitions apply to this document.

road load spectrum

The time history of the generalized loads (such as force, acceleration, displacement, etc.) generated by the test vehicle under actual road surface excitation.

actuator

The actuator drives and controls the movement of the test bench to simulate road loads.

Note. The actuator is usually an electro-hydraulic servo type, which can convert the electrical signals of the control system into mechanical displacement, speed or acceleration output.

control bandwidth

Test the control frequency range of the system's input and output.

Desired signal

The road load spectrum obtained through editing is used to generate the driving file for the bench system within the control bandwidth.

response signal

The time history of the generalized loads (such as force, acceleration, displacement, etc.) generated by the test vehicle under the excitation of the test bench system.
