Sensitivity Analysis of Factors Influencing Blast-like Loading on Reinforced Concrete Slabs Based on Grey Correlation Degree

Blast simulators are capable of applying blast-like loading to components in a safe and controlled laboratory environment, overcoming the inherent shortcomings blast testing terms data acquisition, test cycle time, cost. In this paper, reasonable assumptions refinements made shape impact module, key component simulator, achieve diversity simulated loading. By designing four rubber shapes, importance ellipsoid as an elastic cushion for simulating was determined. order assess effectiveness optimization, numerical calculations based on calibrated finite element model were performed around factors: flat thickness, velocity, modulus mass. Additionally, grey correlation sensitivity analysis carried out evaluate effect these factors reinforced concrete (RC) slab. The results indicate that peak pressure impulse had opposite sensitivities velocity Changes thickness more positive than thickness. An in-depth study role influencing is important design improvement modules.
