摘　　要：机架是电动轮的重要承载部件,为保障电动轮正常运行,需对机架的强度及动态特性进行分析。在有限元软件中建立其计算模型,并对4种典型工况下的强度进行分析,结果表明,机架的强度满足设计要求;利用有限元软件对其进行模态分析,得到机架的4阶固有频率及振型,模态计算结果在合理范围。通过对机架进行强度及模态分析,为其设计及结构优化提供参考。The frame is an important bearing part of the electric wheel.In order to ensure the normal operation of the electric wheel,it is necessary to analyze the strength and dynamic characteristics of the frame.The calculation model is established in the finite element software,and the strength under four typical working conditions is analyzed.The results show that the strength of the frame meets the design requirements.The finite element software is used for modal analysis,fourth-order natural frequency and vibration mode of the frame are obtained,and the modal calculation results are within a reasonable range.Through the strength and modal analysis of the frame,it provides a reference for the design and structural optimization.
