本文介绍了一种计算门座起重机变幅机构驱动功率的新方法一瞬心回转功率法。与传统的方法相比,该法物理概念清楚,表达式简单明了,计算结果精确,便于电算和优化设计。本文先简介瞬心回转功率法的原理,接着运用瞬心功率法计算了国内目前具有的不同结构形式变幅机构的载荷力矩。在此基础上,根据两种不同的方法列出了计算各种载荷力矩的公式。
This article presents a new method of calculating the drive power of the luffing mechanism of a portal crane instantaneous revolving power method. Compared with the traditional method, this method has a clear physical concept, simple and clear expression, accurate calculation result, convenient calculation and optimized design. In this paper, the principle of the instantaneous centering power method is introduced briefly, and then the instantaneous center power method is used to calculate the moment of load of the luffing mechanism with different structures currently in China. On this basis, according to two different methods listed in the calculation of various load torque formula.
