Some crucial loads that current strength design specifications have not taken into account are also considered when assessing the strength of a bogie frame. Calculation methods of these loads come from load analysis. Finite element simulation and fatigue test rig have been used to assess static strength and fatigue strength of a bogie frame. In addition to the two methods, actual running test is also used to assess bogie frame fatigue strength. In finite element simulation method, endurance limit and modified Goodman fatigue limit diagram are two important tools to judge whether fatigue strength of a bogie frame meets requirement. In actual running test method, Miner linear cumulative damage rule is used to assess bogie frame fatigue strength.

“…The shapes of bogies as well as the load conditions, such as static load and dynamic load, are complex. Therefore, various tests including static load tests, fatigue tests, and track tests are required for the design and the strength evaluation of the bogie [1][2][3][4]. The bogie frame is required to last 25 years or longer as the main structure that supports loads of the vehicle body.…”

“…In particular, the fatigue life evaluation method for multiaxial load has not been defined. Therefore, a number of detailed studies on the fatigue life evaluation of bogie frames have been conducted [1,10,11]. However, there have been few studies on the fatigue life evaluation method and the characteristics of the stress history that occur in the fatigue test and the track test.…”

The bogie frame of a railway is an important structural member for the support of vehicle loading. In general, more than 25 years’ durability is necessary. Much study has been carried out in experimental and theoretical domains on the prediction of the structural integrity of the bogie frame. The objective of this paper is to estimate the structural integrity of the bogie frame of an electric railcar. Strength analysis has been performed by finite element analysis. From this analysis, stress concentration areas were investigated. To evaluate the loading conditions, dynamic stress was measured by strain gauge. It has been found that the stress and strain due to the applied loads were multiaxial conditions according to the location of the strain gauge. Fatigue strength evaluations of the bogie frame were performed to investigate the effect of a multiaxial load through the employment of a critical plane approach.
