多载荷耦合作用下飞机液压管路应力分析

在飞机液压系统高压化、轻量化的发展趋势下，研究液压管路的应力及其规律非常重要。综合考虑内部压力和机体变形载荷的作用，对某型飞机液压系统一段液压管路进行了应力数值计算、仿真分析和试验验证，通过三者的对比与分析，验证了仿真分析方法的正确性，为进行全机液压管路静强度服役性能分析奠定基础。对现代飞机中液压管路设计具有一定的工程实践和理论指导意义。

Stress Analysis of Aircraft Hydraulic Pipeline Under Multi-load Coupling

Under the development trend of the high pressure, lightweight of the aircraft hydraulic system, it is very important to study the stress and law of hydraulic pipeline. Considering the effects of pressure and body deformation load, the stress numerical calculation, simulation analysis and experimental verification are carried out on a section of the oil pipe of an aircraft hydraulic system. Through the comparison and analysis of the three, the correctness of the simulation analysis method is verified, which lays a foundation for the static strength service performance analysis of the whole aircraft hydraulic pipeline. The research content of this paper has certain engineering practice and theoretical guiding significance for the design of hydraulic pipelines in modern aircraft.
