Analysis of mechanical behavior and cushioning characteristics of knitted stainless steel metal wire mesh damper under cyclic loading and impact

To effectively reduce the negative impact of impact load during pyrotechnic launch, this paper proposes a new type of vibration-damping method of knitted stainless steel metal wire mesh damper (MWMD) and analyzes its mechanical behavior and cushioning performance. The effects of MWMD wire diameter d and relative density ρ on the mechanical and rebound characteristics of MWMD were studied by quasi-static cyclic compression experiments. The results show that the smaller the diameter d and the smaller the relative density ρ, the more cyclic loading times and the better the resilience of MWMD. On this basis, the finite element simulation model of MWMD is established, and the mechanical behavior of MWMD under cyclic impact load is studied by numerical simulation analysis. The simulation results show that when the wire diameter range is 0.15 mm~0.23 mm and the relative density range is 1.35 g/cm 3 ~1.79 g/cm 3, the MWMD with smaller wire diameter and larger relative density has a good buffer energy absorption capacity, and the energy absorption efficiency reaches 37.11%. With the increase in the number of cyclic impacts, the energy absorption capacity of MWMD decreases. MWMDs with smaller wire diameters and higher relative densities exhibit more stable mechanical properties under multiple impact loads and show stronger resistance to repetitive impacts.
