Structural and Thermal Analysis

Summary

It is very important in design verification and failure assessment for equipment, piping, or structures to predict their complicated structural behavior including thermal effects. TOYO has been utilizing the finite element analysis (FEA) technique for many years to solve various engineering problems and has accumulated various knowledge and experiences for successful FEA applications to such studies.

Application Example of Structural and Thermal Analysis

In a shell & tube heat exchanger, fluid temperature difference between tube inlet and outlet was very large. Such large temperature difference could cause severe thermal stress in the channel cover. Temperature distribution and resultant thermal stress were therefore evaluated by FEA. The largest temperature difference between tube inlet and outlet was considered in the channel cover modeled as shown in Fig.1. Temperature and stress distributions were computed as shown in Figs.2 and 3. Based on these results, it was verified that the maximum stress was within the design limit.
TOYO utilizes such structural and thermal analyses technologies to ensure flawless engineering executions and swift field trouble shootings.
