摘要
根据电机端盖结构特点,将端盖抽象为薄圆环板,应用卡门方程和伽辽金法,建立结构轴对称的电机端盖在不对称载荷作用下的强非线性动力学方程.应用MLP法得到主共振的近似解.分析了系统一次近似解析解及端盖系统的阻尼、外激励力和结构参数(板厚、半径)对振动响应曲线的影响.
According to the structural characteristics of the end-shield of motors,the end-shield can be simplified an thin annular circular plate.Applying the Von Karman equation and Galerkin's method,Creating strongly nonlinear dynamic equations for asymmetry loads end-shield of motor.Using the method of improved MLP to obtain the approximate solution of the primary resonant.Analysis of influence of damping,excitation force and structure parameters on the system is carried out.
