【摘要】:The violent vibration of hydraulic pipelines in aircraft may cause faults or even an accident, especially for the large aircraft with the multi-pump system because of different vibration sources and complex pipelines system. Aiming to the vibration analysis and control of the multipump system, this paper proposed the clamps' locations optimization to minimize the system impedance at vibration frequencies. Firstly, the models of the flexible clamp and other components in multi-pump system were established, based on which, the system impedance was calculated by using Transfer Matrix Method(TMM); Secondly, the objective function is defined as weighted sum of system impedance at frequencies of different vibration sources. Then, the clamps' locations were altered to change the system impedance. Moreover, The Chaotic Swarm Particle Optimization(CPSO) algorithm was applied to obtain the optimal clamps' locations and the minimum value of objective function which decreased by 36.4% compared to the value of original clamps' locations;Finally, the experiments from vibration and pressure test with original and optimized clamps' locations verified the effectiveness of the system impedance calculation and clamps' locations optimization method.
