摘　　要：运用ANSYS有限元分析的方法,通过建模、划分网格、施加载荷、求解分析得到PTC热敏电阻的瞬时热电耦合场。经过仿真,得到PTC热敏电阻电流—温度的关系,为以后蓄电池恒流放电装置的设计打下基础。By adopting ANSYS finite element method, the transient thermoelectric coupling field of the PTC thermistor is gotten through modeling, meshing, loading and analyzing. The relationship between the PTC thermistor current and temperature lays is gained by simulation, which lay the foundation for the design of the constant discharge of battery.
