Abstract At present, protective equipment for the gateway of civil air defense engineering is in short supply. According to the characteristics and protective requirements of the horizontal electric blast door, a new design of horizontal electric blast door with both manual and electric forms which can be opened inside or outside is proposed. The layout was put forward which was compatible with manual as well as electric control modes to solve the problem of larger opening force when manual opening. Based on the established finite element model of the door leaf of new horizontal electric blast door, the section and skeleton layout of the door leaf were optimized, and the corresponding load loading and constraint setting methods and suggestions were put forward, the rationality and reliability of the design were verified by simulation analysis. Based on dynamics simulation technology, the simulation model and constraint setting method of electric actuator of blast door were established, and the theoretical peak of thrust required by electric components was determined. The prototype of new horizontal electric blast door was manufactured and tested. The result showed that the blast door ran stably and could meet the civil air defense requirement of level 6 protection resistance. The design and simulation analysis of the new horizontal electric blast door can provide reference for the development of other similar protective equipment.

新型平置电动防护门设计和仿真分析
目前人防工程水平口部的防护设备非常稀缺，针对平置电动防护门的防护特点和要求，提出了一种手电两用、内外均可开启的新型平置电动防护门设计方案，设计了手动、电动两种控制模式兼容的布置方案，以解决手动开启需较大开启力的难题。基于建立的防护门门扇有限元模型，对门扇截面和骨架布置进行优化计算，提出相应的载荷加载和约束设置的方法和建议，通过仿真分析验证了设计的合理性和可靠性。基于动力学仿真技术，建立了防护门电动执行机构的仿真模型和约束设置方法，确定了电动部件所需推力的理论峰值。制作了新型平置电动防护门的样机并进行试验，结果表明该防护门运行稳定，可满足６级防护抗力的人防要求。提出的平置电动防护门设计和仿真分析技术可为其他类似防护设备的研制提供参考。
