基于ANSYS WorkBench一字型转轴扭矩分析

Torque Analysis of Linear Type Hinge Based on ANSYS WorkBench

通过ANSYS Work Bench中瞬态动力分析模块对新型一字型转轴进行了扭矩分析,分析中,锥片变形设为非线性,根据实际情况设置了接触面的摩擦因数。分析结果表明,在转轴工作过程中,锥片均为弹性变形,变形不均匀,摩擦应力分布不均匀,锥片与轴套绝大部分处于滑动状态,小部分会产生粘连,接触面之间几乎没有穿透,锥片与轴套间的摩擦力随着轴芯位置呈现非线性增大,并得出转轴扭矩与轴芯位移之间的非线性变化曲线。

Torque analysis of linear type hinge by transient structural in ANSYS WorkBench, in the analysis, the deformation of cone pieces is nonlinear, the friction coefficient of the contact surface is set up according to the actual situation. Analysis results show that cone pieces are elastic deformation, inhomogeneous deformation, friction stress distribution is not uniform, the vast majority of cone pieces and sleeve in sliding state, small part will produce adhesion, little penetration between the contact surfaces, the friction force between the cone pieces and the shaft sleeve increases nonlinearly with the central spindle displacement, the nonlinear curve between the torque of the hinge and the displacement of the spindle is got.
