本文介绍一种简便有效的分析计算动平衡的方法。它的原理,就是把一个质量分布不平衡的转子,假想成一个简支梁,把转子两端的轴承看成这个梁的支座,根据平衡条件分析计算梁的支座反力,当惯性力所引起的支座附加动反力为零时,即达到动平衡的目的。对于大部分工程技术人员来说。计算简单梁的支座反力是很熟悉的,所以这个方法很实用,很易掌握。下面通过一个例子来说明该方法的具体应用。 This article describes a simple and effective method of analyzing and calculating dynamic balance. Its principle is that a mass imbalanced rotor is assumed to be a simply supported beam, and the bearings at both ends of the rotor are considered as the bearings of the beam. The counterforce of the beam is calculated and calculated according to the equilibrium condition. When the inertial force Caused by additional kinematic support bearing zero, that is to achieve the purpose of dynamic balance. For most engineers and technicians. Calculating the bearing of a simple beam is very familiar, so this method is very practical and easy to grasp. The following uses an example to illustrate the specific application of the method.
