基于ADAMS的某大型液压挖掘机建模与仿真分析
Simulation analysis and modeling of a large hydraulic excavator based on ADAMS
摘要
Abstract
By taking a certain type of a large excavator as the research object,the chassis and track beams are fixed by multiple row of bolt groups in design.The three-dimensional model of all parts was set up based on the Pro/E.Then convert the format and put them into the ADAMS,adding a constraint condition to establish the virtual prototype system.Based on the ADAMS dynamic simulation analysis,the load condition of each articulated point could be imitated veritably.The simulation analysis is carried out on several typical working conditions.It is concluded that the position and the main force curve of the bolt group with the maximum load of the connecting bolt groups of walking frame in the work.The analysis results can provide data support for strength verification and fatigue calculation of connecting bolt groups of walking frame.The outcomes also provide reference for the optimization and reliability design of the connecting of walking frame.关键词
