【摘要】：电动滚筒作为一种驱动装置,由于长期受到交变载荷作用需要进行结构强度和疲劳强度试验。针对某滚筒厂自行搭建的物理试验台测试时间长,消耗资源多,样机制造难等缺点,在电动滚筒设计过程中结合虚拟试验技术,利用虚拟样机进行虚拟试验,以达到对其结构强度和疲劳强度测试的目的,避免了物理样机的生产,缩短了设计周期,降低了研究成本。搭建电动滚筒虚拟试验平台,为电动滚筒的研究指出新的道路。本文针对电动滚筒虚拟试验平台的搭建进行研究。首先采用参数化设计方法把电动滚筒设计过程参数化、自动化。其次对Solid Works软件进行二次开发,使电动滚筒虚拟样机模型的建立过程自动化。最后通过ANSYS Work Bench有限元软件建立电动滚筒虚拟试验环境,分析其结构强度和疲劳强度。通过开发电动滚筒虚拟试验平台应用程序,实现电动滚筒设计、实体模型建立和有限元分析的一体化。利用电动滚筒虚拟试验平台应用程序,分别设计和建立壁厚为5mm、4mm和3mm的滚筒体装配体,并对其进行虚拟试验分析,得到滚筒体米塞斯等效应力、变形、寿命和安全系数随壁厚减小的变化规律。并总结了滚筒体应力和变形在轴向和周向分布规律。壁厚减小为3mm的滚筒体通过结构强度和疲劳强度虚拟试验,与工厂物理试验结果一致。电动滚筒虚拟试验平台可减少物理试验,节约企业成本。
[Abstract]:As a kind of driving device, electric roller needs structural strength and fatigue strength test because of the action of alternating load for a long time. In view of the shortcomings of the physical test bench built by a roller factory, such as long test time, high consumption of resources and difficulty in manufacturing the prototype, virtual test is carried out by using virtual prototype in the design process of electric roller combined with virtual test technology. In order to achieve the purpose of testing the structural strength and fatigue strength, the production of physical prototype is avoided, the design cycle is shortened, and the research cost is reduced. A virtual test platform for electric roller is built to point out a new way for the research of electric roller. In this paper, the construction of electric roller virtual test platform is studied. Firstly, the design process of electric roller is parameterized and automated by parameterized design method. Secondly, the software of solid works is redeveloped to automate the process of establishing the virtual prototype model of electric roller. Finally, the virtual test environment of electric roller is established by ANSYS work Bench finite element software, and its structural strength and fatigue strength are analyzed. By developing the application program of electric roller virtual test platform, the integration of electric drum design, solid model building and finite element analysis is realized. Using the application program of electric drum virtual test platform, the cylinder assembly body with a wall thickness of 5 mm or 4 mm and 3mm is designed and built, and the virtual test analysis is carried out to obtain the equivalent stress and deformation of the cylinder body. The variation of life and safety factor with the decrease of wall thickness. The distribution of stress and deformation in axial and circumferential direction is summarized. When the wall thickness is reduced to 3mm, the virtual test of structural strength and fatigue strength of the roller body is carried out, which is consistent with the results of the factory physical test. The electric roller virtual test platform can reduce the physical test and save the cost of the enterprise.
