摘　　要：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。The temperature increase in elevator-safety clamp of explosion-proof elevator is a complex coupling of heat-mechanical. This paper develops a way to get the boundary conditions of FEA model from an analytical expression of the instantaneous heat flux in a viewpoint for system energy, while establish the three-dimensional transient heat transfer FEA model of the elevator-safety clamp, and thus reach a more desirable data model to build a elevator-safety clamp transient temperature field. Experimental study also verified that the right data model can better predict the elevator-safety clamp＇s friction temperature trends over time.
