And Function

In this paper, the application background and function of vibration test is introduced. Besides, the composition and working principle of vibration test system is also introduced simply. Furthermore, the characteristic of water and oil is compared with each other in the paper. It is discussed if the water hydraulic is able to be used in the hydraulic vibration test-bed or not. The capability of hydraulic vibration test-bed based on water is simulated by Matlab software. The feasibility of this project is also analyzed.

Elastic Couplings

The powertrain of vehicle is actually a multi-freedom torsional vibration system, its torsional vibration directly affect the vehicle’ ride comfort and safety. In this paper, the effects of elastic couplings on the newly built torsional vibration test-bed were researched. Firstly, using the basic principle of equivalent conversion, established the torsional vibration equivalent model. Secondly, analyzed the free torsional vibration of the powertrain by the dynamics analysis software-ADAMS and obtained the torsional vibration characteristic of the powertrain with different elastic couplings. Finally，fitted out the curve of stiffness and natural frequency by the least squares method.

Order Analysis

The torsional vibration is a kind of particular vibration form which exists in the work process of the vehicle’s transmission. It is easy to cause the noise and vibration of the vehicles, which will affect the riding comfort and even lead to serious safety problem. On the basis of mechanism analyzing of the torsional vibration, this paper studies on the torsional vibration of the vehicle’s transmission by order analysis method. Through the torsional vibration test under a certain working condition on test bed, the order analysis method is proved to be valid and accurate. So it can provide reference for the design of the transmission and its improvement.
