| The paper aims to study the influence of pipeline direction and clamp position on pipeline stress. Aircraft typical hydraulic pipeline was taken as the research object to model the dynamic parameters of the pipeline system and supporting structure. MATLAB and MSC.NASTRAN were used to construct an automatic vibration reduction optimization calculation platform. This paper took minimizing the dynamic stress response of pipe wall and supporting structures as optimization calculation target, optimized and calculated the pipeline route (including turning positions and curvature radius) and clamp positions, and finally constructed the automatic optimization calculation method in design of aircraft pipeline system. Using the automatic vibration reduction optimization calculation platform built in this paper reduced the aircraft typical hydraulic pipeline system’s maximum dynamic stress value by 50%. The optimization method provided can effectively reduce the stress level by optimizing the pipeline layout parameters. |
