Study On Response Of Ship Structure Under Non-contact Explosion Shock Wave

A warship involved in a battle would encounter the assault from enemy anti-warship weapons. In the light of its destructiveness,such assaults can be divided into contact explosion and non-contact explosion,and the the latter can be divided into that in the air and that under water. Non-contact explosion mainly causes destruction to a warship's structure,apparatus and equipments. The present paper,with its focus on warship dynamical response problems under non-contact explosion that in the air and that under water,researches on the some issues by virtue of theoretical analysis and numerical computation. The main researches and conclusions in the paper are as follows:1. Research on non-contact explosion shock wave problem both in air and water. The non-linear transient dynamical software MSC.DYTRAN can solve the explosion shock wave problem properly. Numerical computation and experiential results are accordant. Availability and accuracy of the software are proved. Effect of different element density and equation state of...
