摘要:
安全压杆是安全座椅上的重要组成部分,用于保护乘客人身安全。在设计的过程中,往往缺乏极限状态的计算,且没有考虑乘客身高这一因素,容易导致乘客头部磕碰等安全隐患的发生,为此文章提出了一种基于有限元和运动分析的结构优化方法。方法:首先采用有限元方法分析了主要零部件的极限强度;然后,对压杆的运动过程进行仿真分析,获得了限制压杆抬升的主要影响因素;最后,对安全压杆从结构和机构两方面进行了优化设计。该优化方法对安全压杆的设计具有一定的指导意义。
Abstract:
Safety pressure strut is an important part of the safety seat, which is used to protect the personal safety of passengers. In the process of design, the calculation of limit state is often lacking, and the factor of passenger height is not considered, which is easy to lead to potential safety hazards such as passenger head collision. Therefore, a structural optimization method based on finite element and motion analysis is proposed. Methods: Firstly, the ultimate strength of main parts was analyzed by finite element method then, the movement process of the strut is simulated and analyzed, and the main factors restricting the lifting of the strut are obtained finally, the safety strut is optimized from two aspects of structure and mechanism. The method has certain theoretical guiding significance for the design of safety strut.
