Abstract：Objective To construct a finite element model using trinitrotoluene(TNT)equivalence method to calculate the damage distance of oil tank explosions,aiming at the problem of safety range of oil tank explosions.Methods The TNT equivalence method was used to parameterize the oil and gas in the tank and analyze the error,and obtain the equivalent TNT operating parameters of the oil and gas in the tank.A finite element model was established to simulate the distribution of shock wave and fireball heat radiation,and then the overpressure peak calculated by equivalent TNT was compared and corrected with that measured at the explosion site.A trial model with minimum error was obtained,and then the safety distance between the shock wave and thermal radiation damage was determined by the damage criterion of shock wave and thermal radiation.Results The damage distance of shock wave was 14.65 m and the damage distance of thermal radiation was 49.6 m calculated by finite element analysis and model calculation based on the peak value of shock wave overpressure collected in the experiment.Conclusion The finite element model of oil tank explosion established by using TNT equivalence method can be used as a method of explosion damage assessment.
