| Summary: | At present, the research on emergency departure is mostly about the departure track or the departure system. The strength analysis of the emergency door actuator is rarely involved. Based on the idea of function conversion, the transient dynamic analysis method is used to analyze the impact strength of an emergency door actuator. The calculation results show that the impact strength of the emergency exit door actuator has a great relationship with the explosion pressure, the volume of the combustion chamber and the quality of the piston rod assembly. At the same time, the weak link and dangerous area of the actuator are also obtained. Fillet section between actuator piston rod and impact parts of outer cylinder is the weak link and dangerous area.
