装载机动臂横梁的断裂分析

Fracture Analysis for Mobile Arm Beam of Loader

装载机是用来挖掘、装载和搬运松散物料的机械,由于其工作过程循环往复,且负载情况经常发生变化,工作装置中各构件难免发生破坏,其中破坏最严重的是横梁。文中对造成横梁破坏至断裂的各种可能的原因进行了分析,为后面的力学计算做了充分的准备。

Loader is a machine for digging or loading or conveying incompact materials. Due to circulation and changing loads on its jobs, components of equipment could be destroyed inevitably. One of the most severe components is its beam of loader. The paper studies the possible reasons of beam fracture, which put preparations for the later calculations.
