Topology optimization of slider-crank mechanism under dynamic loading

Parts in the mechanical system can be optimized individually regarding the static or modal analysis. However, during the motion of an assembly, parts move together and applied forces and configuration of assembly changes along with the motion. While the mechanism is in motion, situations different from those analysed and optimized in static conditions may be encountered. In addition, while the individual and statically optimized parts are in motion within the mechanism, the boundary conditions of each part in space change depending on time. Angle changes relative to the motion of the mechanism require modal analysis for each angle and static analysis again. In this case, mechanism type of structures and/or machine systems are simulated in dynamic environments and optimization processes include this type of dynamic analysis. The main purpose of this study is to test mechanism type of structures and machines in dynamic environments and to find the most suitable dimensional values according to stress and natural frequency constraints. Developing a parametric approach using Abaqus and SolidWorks in the Isight environment is the main goal of this study. The systems to be examined in this research are the simple and realistic crank-slider mechanism systems.
