摘　　要：针对某洗扫车直驱专用风机,结合数学理论模型,运用有限元分析软件对其结构进行受力及模态分析。根据研究结果,对风机结构进行优化,使风机满足其结构强度和刚度要求,避免风机使用过程中出现失效现象。为了验证结构优化后的风机是否满足洗扫车使用要求,对其全压及效率进行分析,根据分析结果可知风机的压力流量曲线较平稳,最高全压效率达到7 8.5%,高效流量工作区较广,满足洗扫车的使用要求。For a direct-drive special fan of a cleaning sweeper truck,based on a mathematical theoretical model,the finite element analysis software is used to analyze the force and modality of its structure.According to the research results,the fan structure is optimized to meet the requirements of structural strength and stiffness,so as to avoid failure of the fan during use.In order to verify whether the structurally optimized fan meets the requirements of the cleaning sweeper truck,its full pressure and efficiency are analyzed.It is known from the analysis results that the pressure flow curve of the fan is smooth,the highest full pressure efficiency reaches 78.5%,and the highefficiency flow working area is wide,which meets the requirements of the cleaning sweeper truck.
