摘要
介绍了M1500采煤机摇臂壳体上传感器的安装位置与数量的优化的方法,首先用UG软件对壳体进行三维实体建模,导入到ANSYS Workbench有限元分析软件中进行了预应力下的模态分析,得出固有频率和振型。然后提取所选关键节点处的位移模态,利用逐步累积法,基于模态置信准则(MAC)确定优化的目标函数和约束条件,最终通过MATLAB数值分析得到传感器的最优布置位置及数量。
Describes an approach to optimize the position of the installation and quantity of sensors on the M1500 rocker arm shell of shearer. At first the three-dimensional model of the shell was established with UG , the stressed modal are analyzed with finite element method in ANSYS Workbench software , the natural frequency and principal mode are obtained through modal analysis. Then the displacement modal of key nodes was extracted, using the method of cumulative , the objective function and restriction based on the principle of modal assurance criterion is set, finally, the optimal layout position and quantity of the sensor was acquired with MATLAB.
