Optimization method for civil aircraft maintenance tasks with obvious operation effects of faults by LAI Tao, CAI Jing, ASSILA Achraf

“…In the maintenance planning of civil aircraft, the initial maintenance tasks based on MSG-3 standard for civil aircraft are set conservatively due to the lack of usage data support, resulting in problems such as excessive maintenance and poor economy in practice. An optimization method for civil aircraft maintenance tasks based on the guidance of IP 44 and the process of Boeing statistical analysis for scheduled maintenance optimization(SASMO)is proposed. …”

STUDY ON IMPROVEMENT FOR THE EXCITATION PERFORMANCE OF BV500 TYPE CONTROLLED SEISMIC SOURCE VIBRATOR PLATE BASED ON TOPOLOGY OPTIMIZATION METHOD by HUANG Zhiqiang, FU Mingwei, XI Yuxi, LI Gang, WANG Ruohao, PU Wei

“…During the operation of the BV500 type controlled seismic source vibrator in Sichuan and Chongqing areas, due to the improper plate design, the vibration energy down-transfer rate is low and the excitation signal distortion is serious.Therefore, the continuum topology optimization method was introduced, and a variable density method of the solid isotropic material with penalization (SIMP) model was used to optimize the design of BV500 controlled seismic source vibrator plate from two aspects — reducing mass and increasing stiffness, and an “octagonal I-steel-20a” plate was innovatively developed.After optimization, the mass of the plate was reduced by 45.29%, and the stiffness of the plate was increased by 79.92%, the vibration performance of the plate before and after optimization is studied.The simulation results show that compared with the original aluminum alloy plate, the energy down-transfer rate of the “octagonal I-steel-20a” plate increases by 15.11%，the displacement amplitude of the ground surface contact center point increases by 43.74%, and the amplitude of the interaction force increases by 40.56%.The field experiment shows that when the “octagonal I-beam-20a” plate is excited, the effective value of the average vibration velocity of the near-field signal of the detector is increased by 22.23%, and the effective value of the average vibration velocity of the far-field signal of the detector is increased by 39%, the law is consistent with the numerical simulation conclusion of controlled seismic source road excitation.The excitation performance of the “octagonal I-beam-20a” plate is better than that of the original aluminum alloy integral plate, which effectively improves the road excitation effect of BV500 type controlled seismic source in Sichuan and Chongqing areas.…”
