摘　　要：文章以小型谷物烘干机为研究对象,提出了基于UG/ANSYS Workbench的一体化分析方法。借助UG完成主要部件干燥器、搅龙、阻灰网及搅拌器等结构设计,简化三维建模及整体装配。小型谷物烘干机采用循环烘干法,多次循环低速烘干,通过改进搅龙螺杆叶片的设计结构增加谷物与热风的接触面积,同时还能避免谷物相互挤压,实现更好的烘干效果,减少烘干作业过程中的谷物损耗。利用ANSYS Workbench对关键零件搅龙进行静力学分析求解得到搅龙的等效应力云图和总形变云图,验证小型谷物烘干机整体结构设计的合理性。仿真结果表明,搅龙结构变形量很小,刚性较强,可以满足小型谷物烘干机烘干作业时的强度要求。This article takes small grain dryers as the research object and proposes an integrated analysis method based on UG/ANSYS Workbench.Using UG to complete the structural design of main components such as dryer,agitator,ash blocking net and mixer,simplifying 3D modeling and overall assembly.The small grain dryer adopts a cyclic drying method,which involves multiple cycles of low-speed drying.By improving the structure design of the agitator screw blade,the contact area between grains and hot air is increased,while also avoiding mutual compression of grains,achieving better drying results and reducing grain loss during drying operations.Using ANSYS Workbench to perform static analysis on the key component of the agitator,obtain the equivalent stress cloud map and total deformation cloud map of the agitator,and verify the rationality of the overall structural design of the small grain dryer.The simulation results show that the deformation of the agitator structure is very small,and the rigidity is strong,which meets the strength requirements of small grain dryers during drying operations.
