Fluid structure interaction study of shock absorber for clicking noise refinement

Clicking noise refinement in car shock absorber is studied using fluid structure interaction (FSI) and design of experiment (DOE). FSI helps to refine clicking due to rapid deformation of orifice. Individual effects of rebound cushion hardness (H), cushion height (h), percentage change in oil pressure (Pⱼ) and their mutual interactions on rebound cushion impact noise are investigated using full factorial design. Combination of factor levels for the minimum targeted clicking noise is found as H = 70 shore A, h = 14 mm, Pⱼ = 20% from full factorial design, it is found that H and h have 72.42% and 6.25% contribution on cushion impact noise (SPL - A)f. Interaction between h and Pⱼ is found significant as 20.21% contribution. However, individual Pⱼ obtained from FSI result has shown 0.25% contribution which is insignificant. Correlation is established between FSI and experimental oil pressure (Pⱼ) during nonlinear deformation of orifice.
