摘要
建立了混凝土泵车臂架系统的动力学模型并进行优化分析,获得了受压连杆的最大压力及其对应的臂架位姿,采用两种方法对受压连杆进行静动态分析,避免了单一分析方法的局限性,最后通过自平衡加载试验平台对受压连杆进行试验,试验结果表明连杆位置的偏置对连杆的稳定性及其拉板的应力分布有较大的影响。
The dynamic model of boom-system on concrete-pump was buih, and the optimization analysis was done to obtain the maximum pressure of the compressed rod and the posture of boom system at the exact situation. Two methods were adopted to analyse the rod' s static and dynamic performance, which avoids the defects of single analysis method. A compression experiment was done on the rod using the Self-balance loading test bed. The experimental result tells that bias placing the rod has some effect on the stability of the rod and the stress distribution on its plate.
