A blocked integrated door-ladder mechanism,which can perform lifting,locking,and lowering movements,is adopted on a certain type of aircraft.This paper seeks to optimize and improve the ladder mechanism by simulating and analyzing its movements.Since the design optimization is a multi-round iterative process,and the ladder mechanism is complex,with long motion chains and multiple parts involved,general theoretical calculations and analysis are difficult to implement.Therefore,the DMU module of CATIA software is used to simulate the motion of the ladder mechanism,analyze the cause of the problem found during the simulation,and propose improvement measures.
