Finite Element Analysis of a Slider–Crank Mechanism Using ANSYS Workbench

The slider–crank mechanism is one of the most widely used mechanical transmission systems in engines, compressors, and industrial machinery. Accurate prediction of its structural response under loading conditions is essential for improving reliability and extending service life. This study presents a finite element analysis of a three-dimensional slider–crank assembly using ANSYS Workbench. The geometric model was developed in CAD software and imported into the finite element environment through the STEP format. Appropriate material properties, contact definitions, boundary conditions, and external loading were assigned to simulate the operating condition of the mechanism. The computational procedure consisted of geometry preparation, mesh generation, static structural analysis, and post-processing of numerical results. The structural performance was evaluated through total deformation, equivalent (von Mises) stress, equivalent elastic strain, and displacement distribution. The numerical results demonstrate that the highest stress is concentrated around the pin connection regions where the load transfer occurs, whereas the maximum deformation appears near the free moving components of the mechanism. The obtained stress and deformation patterns are consistent with the expected mechanical behavior of slider–crank systems. The study confirms that ANSYS Workbench provides an efficient numerical tool for evaluating structural integrity and identifying critical locations before prototype manufacturing. The proposed simulation methodology can be applied in the design optimization and reliability assessment of mechanical transmission mechanisms.
