根据一大类要求动态响应特性较好的中高速凸轮的需要，提出一种新型的通用简谐梯形组合凸轮曲线。用这种组合曲线可以构造出不仅加速度连续，而且跃度也连续的运动规律，可以构造出加速度变号处的理论碰撞速度为零的运动规律，与传统的简谐梯形组合曲线相比，这都可以大大地改善动态性能，降低残余振动幅度，所编制的计算机程序具有较强的通用性，便于对各种不同方案进行比较和优选。
According to the needs of a large class of medium-speed and high-speed cams which require good dynamic response characteristics, a new type of general harmonic trapezoidal combination cam curve is proposed. With this combination of curves can be constructed not only the acceleration of continuous, but also continuous movement of the law of jerk, the acceleration can be constructed at the theoretical collision speed zero movement law, compared with the traditional simple harmonic trapezoidal combination curve, which Can greatly improve the dynamic performance, reduce the residual vibration amplitude, the prepared computer program has a strong versatility, to facilitate the comparison and optimization of various programs.
