近年来,由于电子计算机技术在国内得到了迅速的发展。运用一般力学公式上机计算油锯发动机平衡重已有一些先例。但是这种力学计算法由于受到待定平衡系数的限制,只能得到相对精确的平衡重。本文描述了一种应用优化(optimization)技术,建立发动机平衡重的数学模型,并从确定最佳平衡系数的角度出发,求解发动机的最佳平衡重,以达到最佳的部分平衡效果的方法。这在我国油锯发动机设计中是一个新的尝试。也是一般力学计算法所不能解决的问题。为了便于设计者应用,最后还给出了几组计算机解出的模拟数据。
In recent years, due to the rapid development of computer technology in China. There are some precedents for calculating the counterbalance weight of a chain saw using a general mechanical formula. However, due to the limitation of the balance coefficient to be determined, the mechanical calculation method can only obtain a relatively accurate balance weight. In this paper, a mathematical model of engine balancing weight is established by applying optimization technique. In order to get the best partial balance, the optimal balance weight of engine is solved from the point of view of determining the best balance coefficient. This is a new attempt in the design of the chain saw engine in our country. It is also a problem that can not be solved by the general mechanics method. In order to facilitate the designer’s application, finally gave several sets of computer-derived simulation data.
