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。 Based on the virtual prototyping technology, parametric points were set up to parameterize the key structure of shearer adjusting mechanism, and the mechanism optimization multi-objective function and multivariable model were established. By changing the value of each design variable to achieve the optimal solution of the objective function, the structural optimization of shearer height adjusting mechanism was studied in the ADAMS optimization design platform to determine the sensitivity of different design variables to the target optimization Degree of relations, have been useful conclusions.
