【摘要】 本文对制动盘不平衡量检测专用立式动平衡机进行了三维立体结构模型的构建,并将箱体同以往大型设备的箱体特点进行比较,针对以往大型设备箱体结构质量大、笨重、所需材料多导致费用增高、通风散热性差等问题,对动平衡机箱体进行了改进设计,并运用ANSYS Workbench有限元分析软件对动平衡机底部箱体进行了载荷力学性能分析,从而得到箱体上的应力分布及其变化规律,进而验证箱体在结构设计上的合理性和可靠性,同时,对模型进行了动力学模态分析,讨论了箱体前几阶振型的固有频率和振动特性,为同类型盘类转子动平衡机的研究和结构优化提供一种可行性参考,进一步地,在降低研发成本、缩短开发周期方面提供了可行性的借鉴。更多还原

【Abstract】 In this paper, the three-dimensional structure model is built for the special vertical balancing machine for detecting the imbalance of brake discs. And compare the box with the characteristics of the box of the previous large-scale equipment. Aiming at the problems of large-scale, heavy, bulky materials, high cost of materials, and poor ventilation and heat dissipation in large-scale equipment, improvements have been made to the dynamic balancing case body. The ANSYS Workbench finite element analysis software was used to analyze the mechanical properties of the bottom case of the dynamic balancing machine, so as to obtain the stress distribution and its variation on the box. And then,verify the rationality and reliability of the cabinet in the structural design.Simultaneously, through the dynamic modal analysis of the model, the natural frequency and vibration characteristics of the first several modes of the box are discussed. This provides a feasible reference for the research and structural optimization of the same type of disk rotor balancing machine. Further, it provides a feasible reference for reducing R&D costs and shortening the development cycle.更多还原
