摘要：

A two-level vibration reduction index (VRI) allocation method is proposed to guide aircraft vibration comfort design. Firstly, using grey theory and transfer path analysis, the reduced total vibration at the target point is allocated to vibration contributions from main sources. Secondly, the VRI assigned to each dominant contribution is allocated to dampers at critical locations according to generalized costs. Finally, the method is demonstrated through cockpit vibration comfort design. The effective loads transferred from engine mounts are reduced by over 49.17%, and the effective accelerations from these loads through seat-floor dampers are decreased by over 53.95% for a discomfort-free experience.
