基于ANSYS Workbench的轴承结构有限元分析

Finite Element Analysis of Bearing Structure Based on ANSYS Workbench

摘要: 利用ANSYS Workbench强大的动力学分析能力，对滑动轴承结构进行模态分析，和谐响应分析。首先使用三维制图软件UG建立模型并将三维模型导入到我们的分析软件中，设置好对应的材料后进行网格划分，然后求解出滑动轴承结构每一阶的固有频率与振型，然后分析滑动轴承结构在受到正压力的载荷时的稳态响应，最后分析滑动轴承结构在发生共振时的应变和形变，从而得出结论，在使用这个滑动轴承时尽量避免发生共振，尽可能的远离共振点。并且，对每个过程，运用控制变量的分析法，进行比较分析。从而，尽可能全面的模拟发动机曲轴的大部分情况下的振动。

Abstract: Utilize the powerful dynamic analysis capabilities of ANSYS Workbench to perform modal analysis and harmonic response analysis on sliding bearing structures. Firstly, use the 3D mapping software UG to establish a model and import the 3D model into our analysis software. After setting the cor-responding materials, perform grid division, and then solve for the natural frequencies and vibra-tion modes of each order of the sliding bearing structure. Then, analyze the steady-state response of the sliding bearing structure under normal pressure load. Finally, analyze the strain and defor-mation of the sliding bearing structure during resonance, and draw conclusions: when using this sliding bearing, try to avoid resonance and stay as far away from the resonance point as possible. And for each process, comparative analysis is conducted using the analysis method of control varia-bles. Thus, simulate the vibration of the engine crankshaft in most cases as comprehensively as possible.
