目前仍然广泛采用А·И·Зимин提出的公式计算滑块行程末点的飞轮角速度。不少人指出Зимин方法有错误,但未能提出更精确的方法。本文试图在前人成就的基础上探讨解决这个问题的途径。一、Зимин方法要点Зимин将飞轮和摩擦盘的接触区简化为一个接触点,并假设:摩擦盘的角速度ω是常数,摩擦盘和飞轮之间的摩擦系数μ是常数。Зимин认为飞轮所受的摩擦力μ·P_H的方向是“顺着全加速度方向”的,“由于全加速度竖的分量是很小的”,从而假设μP_H“是水平的,跟飞轮轮缘相切”。但是,他在计算“飞轮沿着垂直方向滑动的摩擦功”时又使用
At present, the formula of А · И · Зимин is still widely used to calculate the flywheel angular velocity at the end of the slider stroke. Many people pointed out that the Зимин method was wrong, but failed to come up with a more accurate method. This article attempts to explore ways to solve this problem based on the achievements of predecessors. Зимин Method points Зимин simplifies the contact area between the flywheel and the friction plate as a contact point and assumes that the angular velocity ω of the friction plate is constant and the friction coefficient μ between the friction plate and the flywheel is constant. Зимин considers that the frictional force at the flywheel μ · P_H is “along the full acceleration direction” and “due to the small component of the full acceleration vertical”, so that μP_H “is horizontal and tangent to the flywheel rim ”. However, he used it again when calculating “the frictional force of the flywheel sliding in the vertical direction.”
