摘　　要：薄膜蒸发器转子系统中的不平衡力易导致转子振幅加大,从而加剧刮板磨损,导致刮板失效。采用VB对ANSYS进行二次开发,对薄膜蒸发器转子系统进行模态分析,并对转子某些位置上的不平衡量进行了稳态不平衡响应分析,初步实现了薄膜蒸发器转子动力学分析,为薄膜蒸发器设计及安全运行提供依据。Unbalance force of the Thin-Film Evaporator＇s rotor system can amplify the vibration amplitude of the rotor and aggravate the scraper abrasion,which results in the failure of the scraper. The modal analysis and stable unbalance response analysis of the unbalance mass in different scraper of Thin-Film Evaporator＇s rotor system were realized by the secondary exploration of ANSYS based on VB. Therefore,the rotor dynamics analysis of the Thin-Film Evaporator was completed preliminarily. It provide the basis far the design and security of the Thin-Film Evaporator.
