A new appraisal of the thermomechanical behaviour of a hybrid composite brake disc in a formula vehicle Research Objective This paper presents a hybrid composite brake disc with reduced Un Sprung Weight clearing thermal and structural analysis in a formula vehicle.Main purpose of this study is to analyse thermomechanical behaviour of composite brake disc for a formula vehicle under severe braking conditions. Methodology In the disk brake system, the disc is a major part of a device used for slowing or stopping the rotation of a wheel. Repetitive braking of the vehicle leads to heat generation during each braking condition. Based on the practical understanding the brake disc was remodelled with unique slotting patterns and grooves, using the selected aluminium alloy of (AA8081) with reinforcement particle of Silicon carbide (SiC) and Graphite (Gr) as a hybrid composite material for this proposed work. In First Phase of this Project work, By varying slotting pattern and groove angles the transient thermal and structural analysis using ANSYS workbench ,the hybrid composite disc plate of disk brake is done.The…

Published 2019-10-11 by SAE International in United States
The Cardinal goal of this research work is to fabricate hybrid composites of AA8011 with reinforcement particles of Zr2O3 and Al2O3 which was taken in equal (5wt%) weight percentage. The hybrid composites were cast in a square shape (50x50x50 mm size) under the optimal stir casted process parametric condition, further, it was taken for the forging process. The prepared specimens were induced for uni-direction (x), bi-direction (x and y) and multi-direction (x,y, and z) forging route and the response of microhardness of 53, 68, 81 and 96 VHN were obtained respectively due to microstructural phase changes with an even distribution of particles in the matrix. Thus, the tribological properties of prepared specimens were tested using pin-on-disc Tribometer at room temperature under dry sliding condition of load 5,10,15,20 N and by adjusting the sliding speed as 266 and 531 rpm respectively. The outcomes uncovered all the specimens that the wear rate increments with an increase in load and coefficient of friction show an increase at most extreme load conditions. Wear rate increments with increment in the…

Published 2019-10-11 by SAE International in United States
The connecting rod was manufactured by forging process for enhancing high tensile and compressive load so that it was followed by the machining process and suite the IC engine as a part of the component. The main intern of our proposed work is to manufacture a two set of composites specimen of A356 alloy with reinforcement of 5 wt.% silicon carbide and 10 wt.% flyash processed through two different techniques like stir casting and stir cum squeeze casting route and obtain better mechanical properties. Further, the same properties were taken for modeling and analysing of the developed connecting rod model. Due to the commercial demand, the hybrid composite materials take a vigorous role in the analysis part of the connecting rod model. The FEA analysis is done on the connecting rod for a180cc engine by using Ansys 18.1. The static analysis is done by considering four different cases by altering material library property. The output parameter such as total deformation, Von Mises stress, and maximum equivalent elastic strain are taken in each condition. The analysed…

Modeling and Analysis of Helical and Wave Spring Behavior for Automobile Suspension

Sri Krishna College of Engg. and Tech.-Soundararajan Ranganathan, Sathishkumar Kuppuraj, Girish Vishnu Rajaram Ganesan, Jayasuriya Nandhagopal
Published 2019-10-11 by SAE International in United States
The suspension is an indispensable element of automobiles which plays a crucial role in maintaining stability and the ride comfort. Helical springs are used in automobile suspension for many decades. The stiffness of the spring and presence of shock absorber plays a major role while negotiating a huge amount of load. Therefore, the cost of the suspension increases proportionally in commercial vehicles. In this present work, a helical and wave spring is designed and static cum dynamic analysis is done by using ANSYS 18.1 for comparing their performance and to eliminate the downside of the suspension. The geometry of the helical spring is designed using the helix curve and wave spring is designed using Sinusoidal equation. Modeling of both the springs is done using Solid works 2018. Chrome silicon and music wire are chosen as a spring material. The responses like stress and deflection of helical spring and wave spring for both the materials under static loads of 3000 N, 3500 N, 4000 N is obtained. Further, the dynamic analysis is conducted on both the…

Design and Analysis of De-Lavel Restrictor with Throttle Body for Formula Vehicle

The restrictor is a component which controls the mass flow of air passing to the engine. The proposed work focuses on design and analysis of air intake restrictor of Duke 390cc engine which is used in formula vehicles. As an constrain of this system, the air flows through a single circular throat of diameter 20mm. In past decades conventional venture nozzles were used as a restrictor but it leads to nominal press drop. A de lavel nozzle is a tube pinched in the middle, making an asymmetric hourglass shape. It is used to accelerate a higher supersonic speed in the axial direction. The main objective is to utilize De-Laval Nozzle for the minimal pressure drop. The change in pressure will increases the engine power output. The analysis is done by varying design conditions such as three levels of convergent (12,14 and 16 degrees) and three levels of divergent angles (4, 6 and 8 degrees) are taken into consideration. After numerous CFD Simulations, it is inferred that the optimal angles of 14 and 4 degrees for…
