Stress Analysis of Torpedo Homing Transducer Under Impact Load

In the process of entering the water, the self-guided transducer array built in the head will be subjected to huge impact load. Once the self-guided transducer is damaged, the torpedo will lose the ability to track the target underwater. In this paper, the force analysis of torpedo self-guided transducer under shock state is carried out. Combined with the equivalent circuit model of the self-guided transducer, the sound field transmission model and the impact response of the self-guided transducer are given. In addition, the finite element simulation of the self-conducting transducer is carried out to analyze the transient response of the self-conducting transducer when the head of the transducer is hit by a big impact, and the displacement distribution and stress distribution of each part of the self-conducting transducer are given.
