Kinematic analysis of the slider-crank mechanism of an internal combustion (IC) engine using modern software

    Mechanization in agriculture & Conserving of the resources, Vol. 68 (2022), Issue 1, pg(s) 11-17

    The subject of research in this paper is the kinematic analysis of the slider-crank mechanism of an internal combustion (IC) engine. The piston, connecting rod and crankshaft are the most important moving parts of an IC engine. The performance of IC engines largely depends on the design of the mentioned parts. Special attention should be paid to the kinematic analysis of the slider-crank mechanism, when constructing IC engines. Properly performed kinematic analysis is a prerequisite for the design of an efficient IC engine. Today, there are many software packages that make it much easier for engineers to perform fast and efficient kinematic analysis of machine assemblies. This paper presents the use of kinematic analysis software on the example of a slider-crank mechanism, an IC engine.

    One of the most critical components of an engine in particular, the connecting rod, has been analyzed. Being one of the most integral parts in an engine’s design, the connecting rod must be able to withstand tremendous loads and transmit a great deal of power. This study includes general properties about the connecting rod, research about forces upon crank angle with corresponding to its working dependencies in a structural mentality, study on the stress analysis upon to this forces gained from calculations and optimization with the data that gained from the analysis. In conclusion, the connecting rod can be designed and optimized under a given load range comprising tensile load corresponding to 360o crank angle at the maximum engine speed as one extreme load, and compressive load corresponding to the peak gas pressure as the other extreme load.
