Abstract: A road simulation apparatus wherein front excitation means capable of exciting a front axle of a motorcycle upwardly and downwardly as well as forwardly and rearwardly is connected to the front axle of the motorcycle while rear excitation means capable of exciting a rear axle upwardly and downwardly is connected to the rear axle so that a road load proximate to that experienced by a motorcycle actually running on a road can be reproduces. A bendable link mechanism L comprised of a plurality of links La and Lb are disposed in the forward and rearward directions of the motorcycle for permitting mutual bending motion therebetween is connected for pivotal motion to a stationary support member S. The posture of the test vehicle body is maintained while the regeneration accuracy of road loads is augmented.

Abstract: A motor vehicle vibrating system vibrates a motor vehicle having front and rear axles rotatably supported on a motor vehicle frame to simulate the load which would be applied from an actual road to the motor vehicle. The motor vehicle vibrating system has a first vibrator for vertically vibrating the rear axle, a second vibrator for vertically vibrating the front axle, and a third vibrator for vibrating one of the front and rear axles back and forth in a longitudinal direction of the motor vehicle.

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.

Abstract: The present invention provides a which enables a person to experience the effect of change of an actual elastic component of a vehicle for an elastic component of another design without changing the actual elastic component.
