Numerical Simulation of Damage Effect of KE-rod to TBM Warhead

To study the damage effect of Ke-rod to TBM warhead,according to the literature research,TBM warhead structure can be divided into four parts: nose cone,former equipment chamber,warhead compartment and control cabin. On the basis of the analysis,the equivalent structure models of the four sections were established. Therefore,through the Autodyne program to calculate the impact effect of Kerod to nose cone,former equipment chamber and warhead compartment with high speed and different angle. The results of simulation analysis show that Ke-rod can hardly intrude into TBM warhead through nose cone,but can make TBM warhead damaged by penetrating former equipment chamber,what is more,Comp. B in warhead compartment will be initialed conditionally and the detonating conditions have been got for detonating conditions.
