圆向量函数法在侧面起重机受力计算中的应用

摘要

通过圆向量函数法，以计算侧面起重机受力为算例，介绍了圆向量函数在机构分析中的运用。通过圆向量函数建立主要变幅液压缸受力与吊臂转角之间的函数关系，通过Matlab软件编程，计算出吊点全部运动范围内任意位置处上臂液压缸与下臂液压缸的受力。该方法可以拓展到其他的机构分析中。%The paper introduces the circle vector function method,its application in structural analysis with the side crane as an example,and the function relation is built between the stress of luffing hydraulic cylinder and turning angle of the lazy arm.Through Matlab software programming,the force between hydraulic cylinders of both upper and lower arms is calculated within any position of the motion range of the lifting point.The method can also be applied to other structural a-nalysis.
