论文系统的分析了应急滑梯的撤离速率,给出了撤离速率的理论曲线,建立了应急滑梯的三维几何模型,并利用LS-DYNA软件建立了应急滑梯的有限元模型,成功模拟了乘员撤离过程,得到了应急撤离速度参数的变化规律。同时,为了讨论乘员撤离过程数值计算的准确性,该文对设计制造的滑梯试验样件进行了验证试验,并与数值计算结果对比,分析了滑梯不同工作内压对撤离速率的影响。
The paper systematically analyzed the evacuation rate of the emergency slide, gave the theoretical curve of the evacuation rate, established the three-dimensional geometric model of the emergency slide, established the finite element model of the emergency slide by using LS-DYNA software, successfully simulated the evacuation process , Got the evacuation rate of emergency evacuation parameters. At the same time, in order to discuss the accuracy of numerical calculation of passenger evacuation process, this paper tests the designed and manufactured slide test sample, and compares with the numerical calculation results to analyze the effect of different work internal pressure on the evacuation rate.
