Effective acceleration design for solving excessive vibration in the cockpit

To address the issue of vibration discomfort caused by excessive in cockpit, a method that allocates reduction index (VRI) to different transfer paths is proposed. By combining identified contribution sources using path analysis (TPA) with evaluated relative difficulty levels design these through fuzzy analytical hierarchy process, allocation weights can be constructed, which enables VRI at target location allocated paths, and effective amplitude values acceleration transferred designed. Then, specific process illustrated study case on designed cockpit floor-seat connection. The results show achieve level cannot felt this location, amplitudes from main landing gear compartments engines need reduced least 61.55 % 77.23 %, respectively. This effectively allocate guide comfort design.
