Abstract: The present paper proposes comparative study between Double Wish-Bone and Macpherson Suspension system. The objective is achieved by using ANSYS simulation package. Dynamic and static loads are applied on the suspension systems. Various analysis such as Structural analysis with static as well as dynamic loading, Modal analysis and Transient analysis are carried out in order to study deflection, stress, frequency and strain of both the suspension systems and a thorough comparative study is accomplished.

TL;DR: In this paper , the dynamic performance of composite face sheets and core materials is investigated with various configurations of a honeycomb core material to enhance the stiffness and damping properties of composite faces.
Abstract: In the present study, the numerical and experimental investigations on the dynamic performance of tapered composite sandwich plates with various configurations of a honeycomb core material are presented. The tapered composite sandwich plates are considered with the tapered composite plates as face sheets and honeycomb structure with and without strip reinforcements as core materials. Various tapered composite face sheets are formulated by dropping the plies longitudinally at various locations. Further, the various honeycomb core materials are designed such that stiffeners are reinforced at various locations longitudinally and transversely within the honeycomb patterns to enhance the stiffness and damping properties. Higher order Shear Deformation Theory (HSDT) is used to derive the governing differential equations of motion of the various honeycomb tapered composite sandwich plate and solved numerically. Experimental tests are performed to identify the various mechanical properties of composite face sheets and core materials. Various composite sandwich plates are also fabricated to perform the modal analysis and identify the dynamic properties. The effectiveness of the developed numerical model is demonstrated by comparing the natural frequencies and loss factors identified through experimental tests on the prototype sandwich plates. Various parametric studies are also performed to investigate the effect of strip reinforcement in the honey comb patterns, ply drop off and taper angle of face sheets, aspect ratio of sandwich plates, ply orientation of face sheets and boundary conditions on the free vibration characteristics of the tapered composite sandwich plates. In addition, the transverse vibration responses of tapered composite sandwich plates under harmonic force excitation are examined at different types of the honeycomb core design and the performances are compared with those obtained without the addition of composite strips to demonstrate the effectiveness of strip reinforcement in optimizing the stiffness and damping characteristics of the structures. • Tapered sandwich plates are considered with the tapered composite plates as face sheets and honeycomb as core materials. • Various tapered composite face sheets are formulated by dropping off the plies longitudinally at various locations. • Stiffeners are reinforced at honeycomb core materials longitudinally and transversely within the honeycomb patterns. • Higher order Shear Deformation Theory (HSDT) is used to derive the governing differential equations and solved numerically. • Experimental tests are performed to identify the dynamic and mechanical properties of composite materials.

TL;DR: In this article, the authors highlighted the development and analysis path undertaken in the construction of rear suspension system befitting a Formula SAE vehicle and evaluated the structural and functional performance of the proposed system for the 2019 competition.
Abstract: The purpose of this report is to investigate the design development and evaluate the structural and functional performance of the proposed system for the 2019 competition. With the review of the literature surrounding rear suspension systems, FSAE standards, analysis techniques and important design parameters, the foundation for the proposed James Cook University (JCU) 2019 rear suspension system is established. This paper is highlighted the development and analysis path undertaken in the construction of rear suspension system befitting a Formula SAE vehicle. Formula SAE is an international student competition centered on the design, construction and racing of an internal combustion vehicle. All parts are designed via SolidWorks and FEA testing is incorporated using ANSYS to test out various loads under different scenarios in racing. Main components including beam axle, trailing arms, brackets, spring and damper are covered in this paper. The design is focused on providing a low cost and easy to manufacture design which operate for infinite life cycles.
