摘　　要：根据出口动车组最高运行速度,采用仿真分析方法计算作用在聚碳酸酯板前窗上的风压载荷,选取作用在聚碳酸酯板上气压载荷的最大值进行最大变形挠度校核计算。参考有框玻璃抗风压许用挠度设计要求,验证了车辆在最高运行速度条件下,前窗最大变形挠度满足设计许用值要求,为类似结构前窗变形挠度校核提供了计算方法。According to the maximum speed requirements of an export EMU,the wind pressure load acting on the polycarbonate plate front window is calculated by simulation method.The maximum value of air pressure load acting on polycarbonate plate is selected to calculate the maximum deformation deflection.With reference to the design requirements for allowable wind pressure deflection of framed glass,it is verified that the maximum deformation deflection of front window meets the requirements of the design allowable value under the maximum speed of the vehicle.It provides a calculation method for the deformation and deflection check of front window with similar structure.
