摘要：
Based on multidisciplinary design optimization (MDO) method, the rail tube MDO system was established using the optimal volume, least pressure oscillation, the smallest mass and the best inlet position as the objective functions. Taking the multidisciplinary coupling effect into full consideration, the MDO system was solved by the simulated annealing algorithm. The results show that the rail volume is decreased from 21.991 cm3 to 21.756 cm3, with 1.07% reduction ratio; the mass of rail tube is reduced from 1.250 kg to 1.165 kg, decreased by 6.8%. And the pressure fluctuation of the rail tube is dropped from 6 MPa to 5 MPa, with 16.7% fall. The global performance of the rail tube is improved largely.
