Hinge optimization and structural analysis of rotary device for spanning equipment based on ADAMS and Ansys

运用Matlab计算跨越安全防护装置各运动部件的七次插值运动规律曲线,通过Solidworks建立三维模型导入到ADAMS中添加运动规律曲线进行联合仿真,得到初始时刻回转装置受力情况,找到最危险工况,以液压缸铰点受力的最小值为优化目标,通过分析得到的设计参数范围和约束条件得到优化后的值,通过Ansys有限元分析,得到回转装置在两铰点上的受力情况,分析显示回转装置受力情况良好,为以后桁架结构的再优化提供空间。通过优化后的模型进行仿真得到主塔液压缸铰点在全过程受力,校核主塔液压缸的拉压力,符合液压缸拉压杆稳定性要求,对回转装置的优化设计达到目的。

Using Matlab to calculate the seven-time interpolation motion curve of each moving part of the safety protection device,the three-dimensional model is built into the ADAMS through Solidworks to add the motion law curve for joint simulation.The stress condition of the initial moment slewing device is obtained,and the most dangerous working condition is found.Taking the minimum value of the hydraulic cylinder hinge point as the optimization target,the optimized design values and constraints are obtained through the analysis.The Ansys finite element analysis is used to obtain the force of the rotary device on the two hinge points.The display of the rotating device is in good condition,which provides space for re-optimization of the truss structure in the future.Through the optimization of the model,the main tower hydraulic cylinder hinge point is subjected to the whole process stress,and the tensile pressure of the main tower hydraulic cylinder is checked,which meets the stability requirements of the hydraulic cylinder tension and compression rod,and achieves the optimized design of the rotary device for the purpose.
