Abstract

In the design stage of aero-engine pipeline, it is necessary to avoid the excitation frequency of rotator as much as possible to improve the working reliability of pipeline system. Taking the spatial pipeline system supported by multiple clamps fixed at both ends through pipe fittings as an object, the dynamic modeling of the spatial pipeline system is studied according to the finite element theory, and then the vibration avoidance optimization method of the spatial pipeline system is implemented based on the sensitivity analysis of clamp position. Firstly, the finite element modeling method of pipe body with arbitrary shape based on " replacing curves with straight lines " and "coordinate transformation" is proposed. On this basis, two spring pairs are used to simulate the support of the clamp, and "variable cross-section beams" and "spring elements" are used to simulate the structure and elastic constraint of pipe fittings respectively. The finite element model of pipe system is established by assembling each element in the whole coordinate system. Then, the global and local sensitivity of clamp position is analyzed by Chebyshev polynomial, and a local sensitivity-clamp layout optimization method is proposed. Finally, the rationality of the finite element modeling method of spatial pipeline is verified by experiments taking the spatial pipeline supported by three clamps with pipe fittings at both ends as an example. Furthermore, the number of design variables is reduced by global sensitivity analysis, and the clamp layout which maximizes the fundamental frequency of pipeline system is obtained by local sensitivity-clamp layout optimization method. Compared with the initial state, the fundamental frequency obtained by optimization is increased by 50.54%, and compared with genetic algorithm, the solution efficiency of the described method is improved by 86.87 times.
