摘要
针对混凝土泵车臂架在自动浇筑过程中的动力学问题,采用联合仿真的方法对泵车臂架进行了瞬态动力学分析。该方法采用MATLAB对多冗余度臂架进行轨迹规划,然后在SIMULINK建立位置伺服控制系统并与ADAMS中的泵车模型进行柔性体动力学联合仿真。利用仿真结果生成载荷步中性文件并输入ANSYS中进行瞬态动力学分析。分析结果表明,泵车臂架在改造成自动浇筑控制后不会对臂架原有结构造成过大冲击而损坏失效。
In order to reveal the dynamic problem during automatic pouring of truck-mounted concrete boom pump, transient dynamics analysis on the boom is performed. After trajectory planning, co-simulation method is applied to imitate the servo control process of truck-mounted concrete boom pump in ADAMS and SIMULINK. The neutral file exported from simulation result is imported to ANSYS to perform transient dynamics analysis. The analysis result shows that the influence of control algorithm on the boom is accredited.
