than a critical value, which is calculated with respect to the loading of the higher
contact cam – roller.
c) the maximum value of the positive curvature radius of the pitch curve of the cam
not be less than the radius of the cutting tool.
In certain cases, some constraints are excluded by another. For example, the reac-
tion force which stresses the higher contact cam – roller depends to the pressure
angle. As a result, all constraints must be of the equality – inequality type.
2.1 Cam Mechanism with Reciprocating Roller Follower
The applied forces and moments, namely technological resistances, elastic forces of
back spring, gravitational forces and inertial forces, have in the point E (Fig. 1)the
resultant force F3 and the resultant moment M3. The normal reaction force N12,between cam and roller is inclined with pressure angle δ with respect to the
translation direction.
If in the prismatic pair is a play between translating follower and frame, the
contact between these two elements is done in two points (Fig. 1), namely B1 and B2.
The equilibrium equations of the forces which act on the follower in the raised phase
are:the initial angle ψ0 are calculated as solution of a nonlinear programming problem
[2, 4, 5, 10], where the objective function is the maximum radius of the cam pitch
curve Rmax, and the constraints are:d
S0 is the initial space of the follower, h is the follower linear stroke, e is the
offset of follower.I. Simionescu, M. Ene, and L. Ciupitu
摘要 本文提出了几点关于有着摆动式滚子的从动轮的凸轮优化设计。这旨在体现在凸轮的尺寸上，而压力角的约束/或单位应力的幅度较高的凸轮和从动轮或凸轮和滚子之间的接触。最后，解决一个数例的结果出来了。

1. 介绍
从动轮的相对运动是关于凸轮的相对回转运动和相对振荡运动的结合。在这个相对运动中，从动轮边缘与凸轮曲线的间距[8, 9, 10]。凸轮轮廓被看作为相对于凸轮滚子的相对位置的线圈。曲线中心位于螺距曲线中。凸轮的优化设计意在解决一个非线性的问题[2, 4, 5]。它的作用主要体现在如下特点之一：凸轮的最大回转半径，凸轮的整体尺寸，效率 ，以及驱动等等，或是它们的结合。
被考虑到的制约因素有：凸轮压力角的最大值，在凸轮上单位应力的最大值-与从动轮的接触点，凸轮螺距曲线的曲率半径为负的最大值，驱动从动轮的最大值，凸轮螺距曲线的曲率半径为正的最小值，为了避免凸轮的磨损，使得凸轮与从动件之间有着较高的负载能力。
