摘　　要：多级同步感应线圈装置发射过程瞬态能量巨大,可能造成电机损坏,有必要对电机温升进行研究,但考虑到瞬态热有限元仿真时间过长;电流丝法温升计算编程过于繁琐,工作量大等问题,将一维热网络模型计算方法应用于多级同步感应线圈装置中进行算法优化,将电机发热等效成一维传热问题,推导发射电机状态方程,通过Matlab构建同步感应线圈发射装置的一维热网络模型。仿真结果表明:通过不考虑散热情况的理论计算以及对比三维有限元计算结果,对一维计算结果进行校验,一维热网络模型仿真结果与前两者计算误差保持在10%以内。相比于瞬态热有限元仿真与电流丝法计算,在减少了模型搭建难度基础上,显著降低发射电机温升计算时间,提高仿真运算效率。The transient energy of transmission of multi-stage synchronous induction coil devices is huge,which may cause damage to the motor,so it is necessary to study the temperature rise of the motor.However,considering the problems that transient thermal finite element simulation time is too long,temperature rise calculation programming of the current filament method is too cumbersome,and the workload is to large,this paper firstly applies the one-dimensional thermal network model calculation method to multi-stage synchronous induction coil devices for algorithm optimization.Besides,this paper equals motor heat generation to one-dimensional heat transfer to derive transmitter state equation.Then,the one-dimensional thermal network model of synchronous induction coil transmitters is constructed through Matlab.The simulation results show that the one-dimensional calculation results are verified through the theoretical calculation without considering heat dissipation and the comparison of the three-dimensional finite element calculation results,and the simulation error between the simulation results of the one-dimensional thermal network model and those of the previous two is kept within 10%.Compared with transient thermal finite element simulation and the current filament calculation,the one-dimensional thermal network model significantly reduces the calculation time of temperature rise of the transmitter and thus improves simulation operation efficiency on the basis of reducing the difficulty of model construction.
