Shock resistance of supercharged boilers through integration with ship structure

Abstract

The non-linear finite element software ABAQUS was used to simulate the dynamic response of a marine supercharged boiler when subjected to impact loading. Shock resistance was analyzed by the time-domain simulation method. After exhaustive simulations, the effect of air pressure induced by different working conditions on the shock response of a supercharged boiler was reviewed, leading to conclusions about the variability of structural response with different loading parameters. In order to simulate the real impulsive environments of supercharged boilers, the integration of equipment and ship structure was then primarily used to analyze shock response. These distinctly different equipment shock test methods, run under equivalent work conditions, were compared and the causes of discrepancy were analyzed. The main purpose of this paper is to present references for the anti-shock design of marine supercharged boilers.
