1. A vehicle load simulator for detecting a vibration of a travelling vehicle during a field test and for reproducing said vibration, said vehicle load simulator comprising:
- an acceleraration detecting device, mounted on the vehicle;
an integrator for integrating an output from said acceleration detection device, wherein the output from said acceleramation detection device is converted by said integrator into an output indicative of vibration;
actuator means for oscillating the vehicle to simulate a running condition of said travelling vehicle; and
control means for controlling the actuator means in accordance with the integrated output of the acceleration detection device, said control means includingmemory means for storing the output of the acceleration detecting device during the field test,comparing means for comparing the output stored by said memory means with the output detected when the vehicle was oscillated by said actuator means, andcontrol signal output means for generating and outputting a control signal to said actuator means in accordance with the output of said comparing means.

Abstract
A vibration detecting device is provided for detecting a vibration applied to a vehicle, which includes an accelerometer mounted on the vehicle, an inverting amplifier for inverting and amplifying the output from the acceleration detecting device, and an integrator for integrating the output from the inverting amplifier. The output from the accelerometer is converted into a vibration detecting output by the integrator.
