摘要:针对发动机轮盘振动问题,以简化薄壁轮盘结构为研究对象,首先给出解析法求解结构固有频率的具体方法,同时运用有限元方法进行数值求解。实例分析表明,周边固定约束边界条件下的解析解与数值解比较接近,验证了求解方法的精确性。

Abstract:For the vibration of engine’s wheel, the simplified thin-wall wheel was chosen as the research object. Firstly, the analytical solution of natural frequency is given in detail, at the same time, the numerical solution can be obtained by the finite element method. After the case’s study, the analytical solution is close to the numerical solution, when the constraint boundary conditions are fixed edges. It is shown that the methods supplied in this paper can get accurate solution.
Key words:engine;wheel;natural frequency
