摘要：We take the 750 t crawler crane's anti-dumping system as an example,build the hydraulic-mechanical model based on the multi-body dynamics method and the virtual prototype technology.Analysis of the influence on the stability for the main jib is necessary in the situation of sudden unloading.And the regulation of the sudden unloading coefficient is also considered.Co-simulation can take advantages of ADAMS and AMESim.By ADAMS we establish the mechanical system for the main jib,and by AMESim we build the hydraulic modeling.The impact on the stability for the main jib is contrasted under various loading and working angles.At the same time,dynamic response curves of the main jib can be got.According to the boom stress analysis,the sudden unloading coefficient is calculated,and the rule will be compared with design rules for cranes.The stability of the jib and the sudden unloading coefficient are important for the calculation and design of crawler cranes.
