摘　　要：文章通过对金刚石框架锯锯框进行模态试验,获得其各部件的前十阶固有频率,与有限元结果进行对比,数据误差在5%左右,验证了有限元模型和分析方法的准确性。同时基于ANSYS Workbench对锯框模型结构尺寸进行多目标优化设计,减轻了锯框质量,有效降低了成本,同时减少了锯框的最大等效应力,增强了锯框强度,有效提高了锯机性能。By means of modal test analysis for framework of diamond frame saw,ten modal frequencies of each of its parts can be got. Compared the modal test results with the calculated results obtained from the finite element method,it verifies the finite element method to be correct and,meanwhile,helps to correct the finite element modeling process of framework. Based on ANSYS Workbench,it optimizes the structural parameters design of the finite element model. After the improvement and optimization,not only is the mass of the framework reduced but also its stiffness and strength meet the design requirements. At the same time,the performance of diamond frame sawis improved.
