转子不平衡会引起机器零件的剧烈振动。本文介绍一种快速的三步法,用来确定平衡块的位置,以消除振动。这种方法只需使用一只振动计或一只加速计,就可确定所需的平衡重量及其位置,而误差小于1％。为确定最佳平衡重量及其位置: 1.将振动传感器放在机器某一适当位置上(通常放在轴承上),记下某一速度时的振动量。命此读数为α。 2.将一块重量已知的试验块m_t 安装 Rotor imbalance can cause severe vibration of machine parts. This article describes a fast, three-step method for determining the position of a weight block to eliminate vibrations. With this method, a single vibrometer or an accelerometer can be used to determine the desired balance weight and its position with an error of less than 1%. To determine the best balance weight and position: 1. Place the vibration sensor in a suitable location on the machine (usually on the bearing) and note the amount of vibration at a certain speed. Order this reading as α. 2. Install a piece of test block m_t of known weight
