Structure Design of New Airtight Blast Door Based on Topology and Shape Optimization Method

Abstract

Airtight blast door, as the critical component of underground coal mine, requires high quality. Topology and shape optimization were seldom applied in the structure design of products though they were proposed early. Based on those optimization methods and the experience of structure design, a new kind of airtight blast door was developed in this paper. The main component weight of thus kind of door is 14 % smaller than the current airtight blast door without reducing the blast and impact behavior. The typical optimization method and the example presented in this paper are useful for the original development and optimization design in other products.
