摘　　要：针对某折叠式直臂机构存在的举升液压缸力过大及调平精度不满足要求的问题,采用动力学方法对该直臂机构的铰点进行优化设计,在保证臂架的稳定性和作业高度均满足设计要求的同时,将液压缸力降低了15.4%。同时,通过对调平机构铰点优化,保证了调平精度。In view of the problems of excessive lifting hydraulic cylinder force and unsatisfactory levelling accuracy of a folding straight boom mechanism,the hinge point of the straight boom mechanism is optimized by using the dynamic method,which reduces the hydraulic cylinder force by 15.4%while ensuring that the stability of the boom and the working height meet the design requirements.At the same time,the hinge point of the levelling mechanism is optimized to ensure the levelling accuracy.
