防爆电梯安全钳制停温升是一个复杂的热机耦合问题。文章在建立钳块三维瞬态传热有限元分析模型的同时,从系统能量的角度求取瞬时热流密度的解析表达式并将所得瞬时热流密度作为边界条件,从而较为理想地构建了安全钳瞬态温度场的数据模型。实验结果验证了该数据模型能够较好地预测安全钳摩擦温升随时间变化的趋势。 Explosion-proof elevator safety clamp temperature rise is a complex heat engine coupling problem. In this paper, an analytical model of instantaneous heat flux density is established from the perspective of system energy and the instantaneous heat flux density is taken as the boundary condition, Data Model of Temperature Field. The experimental results show that the data model can predict the trend of friction temperature rise of safety gear over time.
