摘要
由新型机械增压器4叶、160°扭转角转子系统,在工作过程中的受力特点以及转子系统的结构和装配要求可知,主动转子承受的载荷大于从动转子,从校核的角度只需对主动转子进行校核即可。建立主动转子的受力模型,设定2种不同的转速、压差工况,求出在这2种工况下转子上所受各种载荷的大小。将转子系统进行合理简化后利用三维造型软件进行实体建模,然后对建好的转子实体模型进行网格化离散处理,施加各种载荷、约束等边界条件,设置求解选项并求解。求解后得到系统的总变形、应力和应变等静力学参数,与转子系统各材质的力学性能参数进行对比。结果表明,所采用的分析方法可以较好地反映机械增压器转子系统的力学性能,为新型机械增压器的实际设计提供了可靠的理论依据。
According to the mechanical charac teristics in the process of work and the assembly requirements of the new type supercharger＇s four lobes and 160 degree twisted rotors systems the load which active rotor carried is greater than that of driven rotor, from the angle of checking, only need to check the active rotor. Setting up the active rotor force model and setting different speed and differential pressure in two working condition, working out all kinds of load on the active rotor at last. The active rotor is simplified reasonably first- ly and then established the three dimension model by using CAD software. The model is mashed by finite element software and imposed the boundary condition of co solution items ic parameters, ntact and constrain. and solving them. G such as the total Then, setting up etting some statdeformation, the stress, the strain of the system after solving. Through comparing with the mechanical properties of the rotor system＇s materials, it＇ s known that the analysis of this paper can reflect the mechanical properties of the supereharger＇s rotor system and provide a reliable theoretical basis for the practical design of the new type supercharger.
