小型便携清雪机主轴设计

Design of the Spindle of a Small Portable Snow Cleaning Machine

摘要: 针对我国东北等寒冷地区对清雪的要求，研发出一种新型的小型便携清雪机。主轴是清雪机的关键零件，其强度、刚度等性能直接影响主机的工作，本文根据清雪机的工作要求和轴的设计理论，确定了主轴的主要参数，并使用PRO/Engineer建立主轴的三维模型，最后用ANSYS对主轴进行了静力分析和模态分析。

Abstract: Based on the requirements of snow clearance in cold regions such as northeast region in China, a new type of small portable snow blower is developed. Spindle is the key part of snow cleaning machine, and its strength and stiffness directly affect the working of the main machine. In this pa-per, the main parameters of the spindle are determined according to the requirements of the work of the snow cleaning machine and the design theory of the shaft. Then the three-dimensional model of the spindle is established by using PRO/Engineer. Finally, the static analysis and modal analysis of the spindle are carried out with ANSYS.
