全地面起重机多体动力学仿真平台研究

Study on multi-body dynamical simulation platform for all-terrain cranes

基于目前全地面起重机动力学计算困难的现状,结合多体系统动力学理论,利用MATLAB编写全地面起重机动力学仿真平台.对全地面起重机的结构进行分析,简化出合理的动力学模型,并将仿真结果与ADAMS动力学软件仿真结果比较.通过结果对比及误差分析,证明此动力学仿真平台仿真结果正确可靠,可以作为全地面起重机结构设计的参考依据.

Due to the dynamical computation difficulty of all-terrain cranes,a dynamical simulation platform is established by integrating MATLABTMprogramming and multi-body dynamics theory.Dependent on the structural analysis on all-terrain cranes,a dynamical model is feasibly simplified.And then,the corresponding simulation results are compared with those from ADAMSTM.The accuracy and reliability of this platform are proven based on error analysis and result comparison.Therein,this approach paves a venue for structural design of all-terrain cranes.
