This paper addresses the static strength assessment of bogie frames for PE2 (M, U) series industrial traction units used in the mining industry. Currently, a significant portion of the widely operated PE2M and PE2U traction units has been in service for 40-50 years. Given that the manufacturer-specified service life for these units is 24 years, there is a critical need to justify the feasibility of extending their operation to more than double their original design life. The objective of this research is to determine the mean stress of the bogie frame loading cycle. A 3D model of the bogie frame was developed using SolidWorks, and structural analysis was performed via the Finite Element Method (FEM) in Ansys Mechanical. The finite element analysis results indicated a mean Von Mises stress of 63 MPa, and a safety factor of 2.65. Based on the findings, relatively higher stresses were observed in the zones beneath the central pivot plate of the pivot transom. The low values of mean stress, combined with the biaxiality levels, confirm that the bogie frame possesses sufficient static strength. These research findings can be utilized to evaluate the fatigue strength and residual life of the bogie frame, as well as to justify its service life extension.
The structural reliability of a spray booth frame is a critical factor in ensuring safe and stable operation, particularly for water curtain spray booth systems that support multiple mechanical components and operational loads. This study aimed to evaluate the structural performance of a water curtain spray booth frame...

Metro serves as a core pillar of urban public transportation. As a key operating component of metro vehicles, the bogie directly determines the safety and reliability of train operation. Existing studies on railway bogies have achieved fruitful results in terms of dynamic performance, fatigue life, and other aspects. B...
Crankshaft is a critical component in an internal combustion engine, operating under cyclic bending and torsional loads, making it susceptible to fatigue failure, particularly in regions with high stress concentration and pre-existing defects. Therefore, this study aimed to investigate the effect of defect location on...

Modulus of subgrade reaction, also known as spring stiffness, is commonly referenced in engineering textbooks and routinely adopted by structural engineers in their slabs on ground design for industrial facilities (e.g., warehouse slabs). From a geotechnical perspective, the spring stiffness is not an intrinsic materia...

People spend a substantial proportion of their daily rest time in bed, making sound structural design essential for user health and safety. In this study, a wood bed was modelled and evaluated using the finite element method (FEM) to assess mechanical strength, fatigue properties, and drop-impact behavior under diffe...
It is proposed to assess the mechanical safety of key structural elements under accidental conditions using an ultimate limit surface formed by the joint consideration of local strength criteria for each type of ultimate internal force, without analyzing a single critical cross-section. Such a surface is constructed...
