摘　　要：重载空投系统在抢险救灾和军用空投的过程中发挥着巨大作用,但该系统的故障将会给救灾、作战带来巨大隐患。采用ANSYS Workbench仿真复现主轴磨损状况,通过表面涂层的方式对主轴进行表面涂层修复处理,研究重载空投系统主轴在经过镀铬工艺处理后,其表面黏着磨损的改善状况。实验结果表明:表面处理后的试件在工作压力下有轻微的划痕,但并未出现黏着磨损,从而验证镀层对防止黏着磨损是有效的。Heavy duty airdrop system plays an important role in the process of fighting danger and disaster relief and military airdrop,so its failure will bring about great hidden troubles to disaster relief operations.By ANSYS Workbench,the wear condition of spindle is simulated,and the surface coating of spindle is repaired by means of surface coating.The improvement of adhesive wear on the surface of the main shaft of heavy load air drop system after chrome plating is studied.The experimental results show that there are slight scratches on the specimens after surface treatment under working pressure,but no adhesive wear appears,which verifies that the coating is effective in adhesive wear prevention.
