摘要
针对重型变位机的实际要求,考虑工件重力影响,对变位机主要部件--翻转架进行静力分析,得出丝杠所需提供的轴向力以及翻转轴处的支座反力。在Matlab软件中编程计算,得到变位机翻转过程中翻转架的受力变化曲线,并分析得出两个极限位置。在Solid Works软件中应用COSMOSWorks对翻转架受力极限位置进行有限元分析,得到静力作用下的应力和变形云图,分析结果对于重型变位机的设计加工有指导作用。
Heavy positioner has its own actual requirement,while workpiece gravity influences that badly. Static force analysis of turnover frame is analyzed to obtain screw axial force and the reaction force.In the programming calculation under Matlab,stress change curve of the turnover frame is obtained,which got two limit positions.Its stress and displacement nephogram are got through FEM analyze the two positions.The calculation results paved important guidance way to design heavy positioner.
