Analysis of Rail Buckling Due to High Temperature
Main Article Content
Abstract
The buckling of railway tracks during Thailand’s summer season occurs frequently and is a major cause of problems in rail transport, including increased track maintenance, rail replacements, and even train derailments. This research analyzes the causes of track buckling due to rising rail temperatures using the finite element method with linear buckling analysis. The results indicate that fastening devices installed between the rails and sleepers play a critical role in preventing track buckling as the rail temperatures approach critical levels. For a standard 25-meter-long rail, when at least 25 of the 30 fastening components are properly installed and securely connected to both the rail and the sleepers, the likelihood of rail buckling can be effectively reduced. Under these conditions, the critical buckling temperature of the rail increases to above 80 °C.
