洗扫车吸嘴结构分析及改进

Analyze and Improve the Suction Nozzle Structure of Road Washing-Cleaning Vehicle

针对某型洗扫车吸嘴出现的结构开裂问题,通过收集作业过程中的吸嘴加速度数据,确定吸嘴载荷并进行多工况仿真分析和结构改进,同时对吸嘴进行流场分析,对其吸拾效果进行评估。市场使用情况表明,改进后的吸嘴结构未出现开裂现象,吸拾效果良好。

For a structural cracking problem of suction nozzle of road washing-cleaning vehicle,find out the load of Suction nozzle,analyze and improve the structure,with collecting acceleration data of suction nozzle in the process of work,at the same time,evaluate the effect of absorbing garbage with flow field simulation.The markets show no structural cracking problem of the improved suction nozzle,with qualified effect of absorbing garbage.
