液压挖掘机铲斗油缸当量作用力臂的最大值对铲斗机构的设计有着重要作用.以往是将铲斗油缸行程分成若干级,逐级算出油缸的当量作用力臂,再通过相邻两作用力臂的比较,找出最大值.这不仅计算繁琐,其结果也不准确.本文提供了电子计算机求油缸当量作用力臂最大值的方法,并给出了源程序.按照这个方法,只需把铲斗机构的原始参数输入计算机,计算机便迅速而准确地给出结果.
The maximum value of the equivalent force arm of the hydraulic excavator bucket cylinder plays an important role in the design of the bucket mechanism. In the past, the stroke of the bucket cylinder was divided into several stages, and the equivalent force arm of the cylinder was calculated step by step, and then passed through two adjacent functions. Comparison of the arm to find the maximum value. This is not only computationally tedious, but also the result is not accurate. This paper provides a method for calculating the maximum arm equivalent force of the cylinder and gives the source program. According to this method, only By entering the original parameters of the bucket mechanism into the computer, the computer quickly and accurately gives the results.
