在液压汽车起重机、专用汽车、特种汽车和其它工程机械中,三铰点液压缸的应用非常广泛,其设计方法大多数采用试算法。自变量较多,试算量相当大,且结果的好坏,设计的合理性很大程度上取决于经验。试算起来很复杂,算出的结果较多,还需对计算结果进行大量的分析工作。那么,对三铰点液压缸能否用一组只含一个自变量和几个变量的简单函数关系式表示出三个铰点及液压缸长度等一系列数据关系呢? 以液压汽车起重机变幅缸的三铰点为例,
In hydraulic truck cranes, special vehicles, special vehicles and other construction machinery, the application of three-point hydraulic cylinders is very extensive, and most of the design methods use trial algorithms. There are many independent variables, the amount of trials is quite large, and the results are good or bad. The rationality of design depends largely on experience. Trial calculations are very complicated and there are many calculation results. There is still a lot of analysis work on the calculation results. Then, can a series of data relationships such as the three hinge points and the cylinder length be expressed for a three-point hydraulic cylinder with a simple functional relationship consisting of only one independent variable and several variables? Take the three hinges of the cylinder as an example.
