| Abstract: | The Ansys software was used.Based on the fatigue-cumulative-damage criterion,the reliability of Monte Carlo method was used to investigate the airplane pipeline system.Reliability optimization designs were researched under a random vibration excitation.The sensitivity between dynamic characteristic and clamp？？s locations was presented for the pipeline system.The paper submits the reliability optimization design that satisfies the system？？s assigned reliability level.The reliability of the optimized system could be guaranteed.It supplies a theoretical basis for the structural reliability and design. |
