为解决某型号15t液压挖掘机动臂开裂问题,我们在对其进行焊接工艺、焊接结构和应力分析的基础上,改进了动臂结构,取得了明显成效。1.故障现象挖掘机动臂主要由前叉、上盖板、下盖板、侧板及后支撑组成。某型号15t液压挖掘机在使用过程中出现动臂开裂现象,其开裂高发部位有
In order to solve the cracking problem of the boom of a 15t hydraulic excavator, we have improved the boom structure based on the welding process, the welding structure and the stress analysis, and achieved remarkable results. 1. Symptom Excavator boom mainly by the fork, cover, under the cover, side panels and rear support components. A model 15t hydraulic excavator in the course of the phenomenon of boom cracking, the high incidence of cracking there
