分析了高压辊式立磨的工作原理、结构组成和关键部件的受力情况,建立了高压辊式立磨下摇臂的三维实体模型并进行了有限元分析,分析结果表明:下摇臂的最大应力值出现在下摇臂轴孔与凹槽拐角的连接处附近,最大应力值为116 MPa,远小于材料的屈服强度,结合下摇臂的应变分布情况,指出现行设计的下摇臂结构基本合理.

The principle and the structure of the high pressure roller mill was analysed, the loads acting on the key part of the roller mill deserved. The solid model of the lower rocker arm was built, and the FEM mesh was generated under the pattern of tetrahedron cells. From the result of the FEM analyzing, it was shown that the Maxine value of the equivalent stress was located around the jointed part between the axis hole and the corner of the groove,and the Maxine value of the equivalent stress is about 116MPa, much less than the yield strength of the material. Combine with the equivalent strain distribution, it can be deduced that the design of the lower rocker arm is reasonable.
