5轴底盘油气悬架及转向系统仿真平台开发

摘要

分别利用多体仿真软件ADAMS、流体仿真软件AMESim和数学软件Matlab各自的优点，开发了5轴全路面起重机底盘油气悬架及电液辅助转向系统多学科联合仿真平台。本平台具有参数化自动建模和电液、机械系统的联合仿真功能，应用此联合仿真平台可缩短产品研制周期、降低研制风险、提高设计效益，并为产品性能数据的积累提供软件平台。%The traditional simulation software can only be used in a single physical domain which is not convenient for engineering simulation that usually contains more than one physical domain. We developed a multidisciplinary co-simulation platform for the hydro-pneumatic suspension （HPS） and electro-hydraulic steering system on all-ter- rain crane（ATC） using multi-body simulation software ADAMS, hydraulic simulation software AMESim and math- ematic software Matlab. We can easily study the performance of the suspension system and the control scheme of multi-axle steering system of crane on this platform. Using this platform can shorten the R ＆ D time, reduce the risk of development and improve the design efficiency.
