基于有限元数值仿真方式建立装配式凸轮轴横向滚花塑性过盈装配模型，研究压装后钢管表面滚花区域应力应变特征，并进行了装配式凸轮轴横向滚花压装实验。实验结果与数值模型结果相一致，凸轮片凹槽内壁与钢管滚花外壁通过弹塑性压配形成十字花形啮合。采用算术平均滤波法消除计算误差对计算结果的影响，结果表明，横向滚花装配式凸轮轴压装力呈阶梯状周期跳跃上升;若不考虑齿形影响，随着压装长度的增大，压装力呈多阶段多斜率线性增加。
Based on the finite element numerical simulation, the transverse calendering plastic assembly model of the assembly camshaft was established, the stress and strain characteristics of the knurled surface of the steel pipe after press-fitting were studied, and the lateral calendering and press-fitting experiment of the assembled camshaft was carried out. The experimental results are consistent with the numerical results. The inner wall of the groove of the cam plate and the knurled outer wall of the steel pipe are cross-shaped by elastic-plastic press-fitting. The arithmetic average filter method is used to eliminate the effect of calculation error on the calculation results. The results show that the lateral calendaring force of camshaft assembly increases in a step-like cycle. Without considering the effect of tooth profile, with the increase of press-fitting length, Pressure loading was multi-stage multi-slope linear increase.
