Strength study of a large suspended tower based on numerical simulations

摘要

Regarding the structure and loadings undertaken,suspended tower is a specially vessel in engineering.In this paper,finite element models for a large suspended tower were established.Stress analyses and the static as well as fatigue strength assessment under some load cases with different combination of loadings were performed.It is found that the large suspended tower subjected to the normal working conditions is satisfied to strength requirement according to the JB4732-1995 Steel Pressure Vessels-Design by Analysis.
