摘要
为研究载流梁在电磁场和温度应力共同作用下的影响机理,分析系统参数对载流梁振幅的影响规律,应用动力学方法建立载流梁的非线性热磁弹性理论模型,并求得了主共振幅频响应方程。研究结果表明:当温度、磁场强度、长度、横截面积达到特定值时,系统振幅会大幅增加,研究结果为载流电磁元器件研制中的可靠性、灵敏性设计及运行稳定性提供支持。
In order to study the action of mechanism of current-carrying beam in thermal-magneto-elasticity field and to analysis of the effect of system parameters on the amplitude, the nonlinear vibration equation of current-carrying beam was studied and the primary response equation was obtained based on dynamics method. The results show the amplitude of system will substantially increase when the system parameters reaches a certain value, such as the temperature, magnetic field intensity,length, cross-sectional area and different material. The results provide theoretical basis of the structure design of current-carrying solenoid components.
