某机安装架抗冲击结构改进

A Machine Assembled Frame Impact Structure Improvement

针对某机在冲击试验中出现的安装架铝铆钉断裂问题,对安装架结构与受力进行了分析,找到了导致冲击试验中安装架铝铆钉断裂的原因,通过取消铆钉结构、缩短螺杆悬臂长度和改变螺杆直径3个方面进行改进。经实践验证,该措施能提高安装架的抗冲击能力。

Aiming at the certain machine breakdown problem of assembled structure aluminum rivet, it analyses the structure and mechanics of the assembled structure, get the reason of the machine＇s breakdown in an impact trial. Some improvement measures are taken such as cancel the rivet, shorten radial length of the screw, accretion diameter of the screw.The capability is enhanced to resist impact.
