Explosive Shock Wave Propagation Laws in Pipes with Self-dissipative Structures
To achieve rapid attenuation of the explosion shock wave in the pipeline,this paper proposes a self-dissipative structure of the pipeline,the use of LS-DYNA finite element software for simulation of the propagation of the explosion shock wave in the pipeline,to obtain the propagation of the explosion shock wave in the long straight pipeline and the pipeline with a self-dissipative structure of the propagation of the law,analysis of the self-dissipative structure of the shock wave to achieve the role of the rapid attenuation of the mechanism,and to accelerate the self-dissipative structure of the economic and functionality of the self-dissi-pative structure to accelerate the attenuation of the shock wave is evaluated.The results show that:compared with the long straight pipeline,the peak overpressure of the shock wave in the pipeline with self-dissipative structure decreases significantly with the propagation distance,and after doubling the diameter of the pipeline,the attenuation rate of the peak overpressure is more than 95%,so that the pipeline with self-dissipative structure has a better economic benefit.
