Finite Element Analysis of Engine Room Platform

Structural stress of the first type and the second type engine room platform under different loads was systemicly calculated based on finite element method，characters of stress distribution and variation rule with structural dimension and loads were detailedly discussed.Then connection scheme of platform on the left side and the right side，effects of pretightening force of bolts and tensile force of pull rod on structure deformation of the platform were calculated，and reasonable installation process flow was proposed.
