【摘要】 提出了利用有限元方法再现电梯事故进行电梯安全设计的方法。首先,详细介绍了相关的有限元建模技术。然后,利用乘员动态响应,提出一套适应电梯事故的电梯乘员安全性评价方法。最后,在考虑电梯安全保护装置作用的情况下,将电梯、乘员、保护装置三者整合起来,用非线性显式有限元方法模拟电梯事故,并与真实事故结果比较,初步验证了该方法的可行性。更多还原

【Abstract】 The idea of elevator accident reconstruction and its modeling method were put forward.Using the response of occupants,the method of evaluating occupant safety was described according to the characteristics of elevator accident.Finally,considering the influence of the elevator protector,the accident environment and FE model of elevator system were established and calculated by the explicit finite element algorithm.Comparing the simulation results with real accident,the correctness of the method was proved.更多还原
