OPTIMIZATION OF CRANKSHAFT BY MODIFICATION IN DESIGN AND MATERIAL
Crankshaft is an important component of the internal combustion engine. Due to huge loading and high number of fatigue cycles, crankshaft is prone to early damage and hence reducing the engine life. In this research paper, static structural analysis is performed on crankshaft for a 4cylinder inline SI engine. A three-dimensional model of crankshaft is designed using SIEMENS NX 12.0 software. In order to study the effect of loading, Finite Element Analysis (FEA) is performed on ANSYS 18.1 software by applying load and constraints to the shaft according to engine working conditions. The analysis is performed for locating critical failure in crankshaft. The optimization includes the modification in the geometry of crankshaft which results in safe and efficient design of the crankshaft. The review of work on the crankshaft optimization and design is demonstrated. The materials, failure analysis, design parameters of the crankshaft analyzed here.
Deformation and Stress Analysis of Crankshafts for Single Cylinder and Multi Cylinder Engine
Cumhuriyet Science Journal
The crankshaft is one of the most important loaded components in the engine, as it is experiencing cyclic loads in the form of a bending and torsion. In the study, crankshaft of the single-cylinder engine and crankshaft of the four-cylinder engine were designed in the SOLID WORKS software. Then these designs were transferred to ANSYS software with finite element method. Both crankshafts were compared in terms of stress and deformation. Critical areas had been identified as a result of stress and deformation. Comparative analysis of both shafts was not found in the literature. As a result, the values of stress and deformation increased as the speed increases in both shafts. Stress and deformation increased as the pressure increases associated with the speed applied on the crankpin journal. The stress in the crankshaft of the single cylinder engine was critically occurring on main journal, and the stress in the crankshaft of the four-cylinder engine was critically occurring on the crankpin journal. This much of the stress in the single cylinder engine crankshaft reduces the working life of the shaft. The shaft material should be selected considering the working conditions in crankshaft, or the material should be improved by coating the main journal and crankpin journal.
Evaluating Design of the Automotive Crankshaft for Fatigue Life using Finite Element Method
2014
The project is about the study of static and Fatigue analysis of crankshaft. Crankshaft is most complicated and highly strained engine part, which converts the sliding motion of the piston to a rotary motion by slider crank mechanism. Crankshaft is subjected to cyclic bending and torsional loads due to gas pressure and inertial forces. Due to these forces crankshaft is subjected to bending and torsional stresses with high stress concentration at crankpin fillet and journal bearing fillet. There for it is necessary to study the crankshaft for static and Fatigue analysis. The crankshaft Fatigue and Static analyzed is carried out using commercial FEA software.
A fatigue analysis and life estimation of crankshaft–A review
The main objective of writing review on fatigue life of crankshaft is to investigate the behavior of crankshaft under complex loading conditions. Automobile industries are always interested to develop a new product which will be innovative and fulfill market expectations. All the engine components are subjected to constant to varying load which also varies in direction and due to these, components may fail. Bending and shear stress due to twisting are common stresses acting on crankshaft. Due to the repeated bending and twisting, crankshaft fails, as cracks form in fillet area. Hence, fatigue plays an important role in crankshaft development. Accurate prediction of fatigue life is very important to insure safety of components and its reliability. This review paper considers crankshaft as an important part of engine components, as forces which are acting on crankshaft are many and variable in nature. This paper presents an idea about research undertaken or completed on fatigue life o...

Crankshaft is large volume production component with a complex geometry in internal combustion Engine (ICE), which converts the reciprocating displacement of the piston into a rotary motion of the crank. An effort was done in this paper to improve fatigue life for single cylinder engine crankshaft with geometric optimization. The modeling of the original and optimized crankshaft is created using SOLIDWORK Software and imported to ANSYS software for analysis. Finite element analysis (FEA) was performed to obtain maximum stress point or concentrated stress, to optimize the life of crank shaft by applying the boundary conditions. The maximum stress appears at the fillet areas between the crankshaft journal and crank web. The FE model of the crankshaft geometry is meshed with tetrahedral elements. Mesh refinement are done on the crank pin fillet and journal fillet, so that fine mesh is obtained on fillet areas, which are generally critical locations on crankshaft. The failure in the cra...
Crankshaft Design Optimality and Failure Analysis: A Review
International Journal of Science and Research (IJSR), 2017
The crankshaft in an internal combustion engine converts the linear reciprocating motion of the piston into a rotary motion with a four link mechanism. A crankshaft works in variably complicated conditions, and is subjected to torsional loads due to inertia of rotating components and bending loads due to gas pressure in internal combustion engines. Its behavior is affected by the fatigue phenomenon due to the reversible cyclic loadings. When repetitive tensile and compressive stresses are developed due to reversible cyclic loadings it leads to fatigue phenomenon which can cause dangerous ruptures and damages. Since a crankshaft is a highly stressed component in an engine, fatigue performance and durability of this component has to be considered in the design process Fatigue is the primary cause of failure of crankshafts in internal combustion engines. In this review paper, the design and forces analysis is carried out and fatigue phenomenon in crankshaft and optimal design is studied.
Stress and Fatigue Analysis of a Single Cylinder Engine Crankshaft
DAAAM Proceedings, 2020
To perform a stress analysis of a crankshaft over the entire cycle of an IC engine, one has to possess a loading history, i.e. the magnitude of the load should be available for every position of the crankshaft during the cycle. This loading history has been obtained through a dynamic analysis done in MATLAB and used in the finite element based stress analysis performed in SolidWorks Simulation 2019. After finding the optimal mesh using the manual h-convergence method, the FE analysis yielded the results neccessary for the fatigue life predictions at previously chosen critical locations. Fatigue performance of the crankshaft was evaluated both analytically and numerically.
