The Multi-functional Performance Of The Test Bed Of Engineering Machinery And Tire Adhesion Performance Test Methods Study

To meet the needs of the work devices of construction machinery researching, after analyzed some existing similar experimental platforms, we made the engineering machine multi-function experimental platform on the basis of simplified the hydrostatic loading system. According to the calculation of the match parameters in static, this paper analyzes the dynamic characteristic simulate. We put the two main engineering machine loading which are sinusoidal wave load and step load, and the results indicate that the dynamic responds are satisfied for the needs of the experiments. Besides, this paper analyzes the influence effects of the tire friction coefficient on different parameters, and then put forwards the experiment method of the performance of the tire friction.
