为了解决全地面起重机塔式副臂工况下工作幅度变化问题。利用解析法求出主臂和拉板系统的结构变形,并分析其对幅度的影响,得出主臂、拉板系统对幅度变化的影响因子。使用ANSYS软件计算工作幅度变化值,验证解析计算结果的准确性。结果表明该分析方法能够快速求解出幅度的变化量,为同类型臂架系统的模型简化及受力分析提供借鉴。
In order to solve the all-terrain crane tower jib working conditions under the conditions of change. The structural deformation of the main boom and the pull plate system is obtained by analytic method, and the influence on the amplitude of the boom and pull plate system is analyzed. The influencing factors on the amplitude variation of the boom and pull plate system are obtained. Use ANSYS software to calculate the change of working amplitude and verify the accuracy of the analytical results. The results show that this method can quickly calculate the amplitude variation and provide a reference for model simplification and force analysis of the same type of boom system.
