This article used a combined solution of ABAQUS and FE-SAFE to evaluate the performance predict fatigue life e-clip (a widely in railway system) under cyclic loading. With proposed methods, analysis has been performed 12 working conditions. The results show that inside rear arch shortest it is therefore most critical part, which proved by field observation. Another conclusion insertion depth into cast shoulder (short depth) clip deflection are two important parameters life. mismatch may...
A breakable model of ballast particle is developed by using the Discrete Element Method (DEM). method modelling Under Sleeper Pad (USP) 'elastic rods' proposed. After integrating sleeper, USP and ballast, dynamic train load applied to analyze response bed. The following results can be drawn: (1) increases contact area between sleeper particles, effectively reduces stress. Comparing track traditional track, maximum stress in reduced 26.10%, average 3.22%. (2) breakage particles upper part bed...
In order to investigate the characteristics of lateral resistance polyurethane-mixed ballast with different bonding areas, a sleeper–ballast model was established using discrete element method. The single and combined modes analyzed. results show that increases increase depth shoulder ballast. After crib base reaches 5 cm 15 below bottom sleeper, respectively, there is no significant development resistance. cannot be improved efficiently by slope an effective method improve With gradual...
