  • Fracture failure analysis of left Steering Knuckle arm
    Ordnance Material Science and Engineering, 2006
    Co-Authors: Chen Yun
    Abstract:

    Left Steering Knuckle arm made of 40Cr steel was used after being quenched and high temperature tempered,but early failure occurred in service.The parts were analyzed by metallographic examination.The results show that the reasons of failure are forging flaws on the surface and the microstructure of the material also doesn't meet the service conditions.

  • Fatigue Analysis of Steering Knuckle using Finite Element Simulation: Technical Note
    International Journal of Vehicle Structures and Systems, 2017
    Co-Authors: S. Madhusudhanan, I Rajendran, B. Raguganeshkumar
    Abstract:

    Steering Knuckle is a prominent component of an automobile Steering system. It is subjected cyclic loads from the suspension system during its service life. The Spheroid Graphite (SG) iron is the most commonly used material for manufacturing the Steering Knuckle. Fatigue behaviour is therefore a key consideration in its design and performance evaluation. Geometric modelling and stress analysis of such Steering Knuckle using finite element analysis software is carried out. Then the fatigue life of Steering Knuckle made from SG iron has been evaluated under the different load conditions and the results have been compared.

  • An investigation on the fatigue performance of austempered ductile iron Steering Knuckle
    International Journal of Heavy Vehicle Systems, 2017
    Co-Authors: S. Madhusudhanan, I Rajendran
    Abstract:

    Steering Knuckles are the important components that connect the wheel in a car to the Steering system subjected to time varying load during their life leading to fatigue failure. The study reports on the fatigue performance of the austempered ductile iron (ADI). SG iron can be made up of three compositions: without alloying elements (X), SG + 0.22% (X1) and SG + 0.34% (X2) of nickel. Three sets of Knuckles were heat treated and specimens were cut from Steering arm and converted into test sample (tensile and fatigue) form. The tensile test and fatigue test were done using 250 kN universal testing machine (UTM) and axial fatigue machine at constant load condition for different loads, respectively. The corresponding cycle stresses were recorded and S-N curve drawn. The same composition of Steering Knuckle was used for component level fatigue test at a load of ±4.7 kN constant amplitude mode up to 1 × 107 cycles, but no damage was found.

  • Static Analysis of Automotive Steering Knuckle
    Applied Mechanics and Materials, 2014
    Co-Authors: S. Madhusudhanan, I Rajendran, K. Prabu
    Abstract:

    Steering Knuckle is one of the critical components for a four wheel vehicle which links suspension, Steering system, wheel hub and brake to the chassis. While undergoing varying loads subjected to different conditions, it doesn’t affect vehicle Steering performance and other desired vehicle characteristics. The static strength test for Steering Knuckle is necessary to validate the component according to the application. Here, the Steering arm static analysis of Steering Knuckle was done by using finite element analysis (FEA software) and experimental testing by using hydraulic actuators and fixtures. The result from the virtual Analysis and Experimental analysis has been compared and validated for the SG Iron Steering Knuckle.

  • analysis of Steering Knuckle of all terrain vehicles atv using finite element analysis
    IOP Conference Series: Materials Science and Engineering, 2016
    Co-Authors: S V Dusane, M K Dipke, M A Kumbhalkar
    Abstract:

    Steering Knuckle is the most stress sustaining and critical component of All Terrain Vehicle (ATV). Steering Knuckle is the pivot point of the Steering and suspension system, which allows the front wheels to turn and also allow the movement of suspension arms motion. The light weight and high strength component is always in demanding for racecar application. Lightweight and optimized design of Steering Knuckle is proposed to use for a BAJA SAE INDIA off road racecar. Due to the failure in Knuckle in terrain vehicle after some instances, it has to be modified for better performance. The 3D CAD model created by using CATIA V5 and static as well as model analysis carried out in ANSYS 12 to understand its behavior under operating conditions. All test for frame was carried out on aluminum alloys 6061-T6 & for spindle EN8. The paper discusses the FE analysis of existing and modified Steering Knuckle.

  • Stress Analysis Of Automobile Steering Knuckle Using Finite Element Method
    International Journal of Engineering & Technology, 2018
    Co-Authors: F H. Ad Suhadak, Kamarul Ariffin Zakaria, Mohd Basri Ali, M A. Yusuff
    Abstract:

    This paper aims in identifying effect of constraint point against critical area of 1300 cc national car Steering Knuckle using finite element method. The material of this Steering Knuckle is cast iron ASTM A536. The Steering Knuckle is modeled using a computer aided design software and the dimensions is assigned according to 3D scanning files. Meanwhile, Steering Knuckle is simulate using commercial finite element software where the load is assigned based on three conditions of constraints. The three conditions are fixed at hub, fixed hub and brake clamp and fixed at hub, brake clamp and Steering arm of Steering Knuckle. Result shows that the positions of constraint points are significantly effect on stress value of Steering Knuckle. By acknowledging the presence or absent the effect of constraint on Steering Knuckle will aid in detecting critical area on this Steering Knuckle. Thus, approach could be conducted to optimize and enhance the life cycle of a Steering Knuckle. The data will be further utilized in testing the Steering Knuckle under variable amplitude strain signal.

  • Fatigue Damage Simulation Of Automobile Steering Knuckle Subjected To Variable Amplitude Loading
    2017
    Co-Authors: F H. Ad Suhadak, Kamarul Ariffin Zakaria, Mohd Basri Ali, M A. Yusuff
    Abstract:

    Fatigue damage assessment is essential in determining the durability of automobile components. Several studies have been conducted on fatigue durability of Steering Knuckle using constant amplitude loading. However, most of the engineering structural and components are subjected to Variable Amplitude Loadings (VALs) in service. Therefore, this study aims to present a fatigue damage simulation of automobile Steering Knuckle of a 1300 cc national automobile using finite element analysis. In this study, the Steering Knuckle is modeled using computer-aided design software, in which the dimensions are assigned according to 3D scanning files. The critical area on the Steering Knuckle is determined using commercial finite element software. The strain gauge is then mounted on the Steering Knuckle and connected to a data acquisition system to capture the actual fatigue strain signal while driving on a residential road. The fatigue strain signal is then used as the VAL in the fatigue damage simulation of automobile Steering Knuckle. Forged steel, cast aluminum, and cast iron are used and analyzed in the simulation. Results indicate that the different types of material used significantly influenced the fatigue damage of the automobile Steering Knuckle.
