Analysis and optimization of a structural seat plate

Abstract

To solve the stress concentration problem of the seat plate when shooting on hard ground, the structural design of the mortar seat plate was redesigned. On the premise of ensuring shooting form and stability under soft soil, surface support was used to reduce the maximum stress under hard soil. For the three-dimensional modeling of the new structure's seat plate, a suitable soil constitutive model was selected to draw more accurate conclusions, and the chamber pressure curve of the internal ballistic of the mortar was calculated. The finite element analysis software was used to analyze the Stress distribution in the state. To further reduce the weight of the seat plate and improve its strength of the seat plate, a multi-objective optimization based on a genetic algorithm was carried out. The optimized seat plate significantly reduces mass with reduced maximum stress.
