Evaluation of mean stress under load cycle of PE2M(U) industrial traction unit motorized dumpcar underframe using finite element method
Year: 2025
Type: article
Abstract: This study presents an analysis of the static strength of the underframe of the motorized dumpcar used in PE2M and PE2U industrial traction units by applying the finite element method (FEM). The analysis was conducted to determine the stress–strain state of the underframe structure under the action of vertical operational static loads that continuously affect its supporting elements. A three-dimensional model of the dumpcar’s main underframe was developed in SolidWorks. A corresponding finite element computational model was then created in ANSYS Mechanical, taking into account realistic boundary conditions and material properties. To evaluate the structural safety margin, the maximum equivalent (von Mises) stress and the total deformation were determined. The results indicate that the highest stress values occur near the joints between the central beam and the transverse subframe brackets. The obtained stress levels remain below the yield strength of the material, confirming that the frame possesses sufficient static strength. The findings of this study can be applied to optimise the design of the dumpcar’s underframe, enhance its operational reliability, and extend its service life.
