Taking the high precision RV reducer test bench as the object, it analyzes the layout of the test bench for the RV reducer and its structure characteristics, establishes the finite element model of the test bench with ANSYS simulation platform and obtains the stress and strain under the condition of working load, and discusses the test bench face,the direction of the displacement, the frequency response curve and the first six order modal.The results show that the overall maximum stress test bench is 2.07MPa, the end of the test bench largest stress deformation displacement is 0.003mm to 0.004mm, maximum displacement vibration displacement is 3.88×10-6mm in the first six order frequency response curve.This provides technical support and a theoretical basis for the comprehensive test bench of RV reducer design and manufacturing.%以高精度RV减速器测试台架为研究对象,针对RV减速器测试台架的布局及其结构特点,利用ANSYS仿真平台建立测试台架的有限元模型,并分析了在工作载荷情况下的应力和应变大小,得出测试台架端面各方向的位移频响曲线及前6阶模态.研究结果显示:测试台架整体最大应力为2.07MPa,测试台架端面的受力最大形变位移为0.003~0.004mm,在前6阶位移频响曲线中最大振动位移为3.88×10-6mm,可为减速器综合测试台架的设计及制造提供技术支持并奠定理论基础.
