Sensitivity Research on Optimization Design Variables of Heighten Unit of Shearer Ranging Arm

基于虚拟样机技术,通过设立参数化点,将采煤机调高机构关键结构参数化,建立了机构优化多目标函数和多变量模型。研究了通过改变各个设计变量的值以使目标函数达到最优解的方法,在ADAMS优化设计平台中对采煤机调高机构进行了结构优化研究,确定了不同设计变量对目标寻优的敏感度关系,得到了有益的结论。

From virtual prototype model of shearer ranging unit is investigated with setting parameterized points. The arm, the optimization optimization model is design of heighten multi-objects and multi-variance. The design analysis of the heighten unit of the shearer is on ADAMS by changing the value of each design variable to obtain the optimal solution. The sensitivity of design variables are analyzed in detailed and the design have been improved.
