【Abstract】 The test was performed for determining the vibration characteristics of the bulldozer undercarriage,and the model of the bulldozer buffer system was established.A reasonable range was defined after the effects of the model parameters on the transmissibility were analyzed.The Nomogram of damping material is digitized,the dynamic curve data on the graph are automatically inquired with computers,and the dynamic optimizations are realized for the damping buffer structures.The design theory and method has been mastered.These results have been applied into development of the viscoelastic suspension undercarriages of the 242kW bulldozers.更多还原
