STRUCTURAL ANALYSIS OF THE PASSENGER NT-60 BOGIE WAGON BOGIE TYPE
Rekayasa MesinThe welded bogie railway was typically exposed to very intricate fatigue loads, resulting in a significant risk of failure. However, most standards only took into account external excitations from wheel-rail system when evaluating fatigue performance. NT-
