Abstract:Based on the dynamic design method DDAM, the finite element simulation calculation model of an exhaust cooling device was established. The dynamic shock response calculation and analysis were carried out. On this basis, the structural optimization scheme was proposed. Based on the comparison of shock stress response results before and after structural optimization, the structural optimization direction to improve the anti-shock performance of exhaust cooling device was defined.
Key words:  DDAM; exhaust cooling device; structure; anti-shock
