Abstract
In order to reduce the cylinder work force on pull tower linkage of self-erecting tower crane, the geometric parameters of hinge points about linkage mechanism were optimized. Through the force analysis to whole system of bar linkage, the cylinder force of bar linkage is regarded as optimization objective function, and the geometric parameters of working devices hinge points are used to variables, then, the optimization model is established. The optimization design is conducted based on the fmincon function of MATLAB optimization toolbox. The curve about force of the cylinder with the towers rotation angle variation can be obtained. Comparison of the results before and after optimization is showed that the maximum force of cylinder is reduced 11.5%. It is shows the optimization method is quickly and effectively. The results of parameter optimization improve the working performance of the self-erecting tower crane.
