TL;DR: In this paper, a comparative study between Double WishBone and Macpherson suspension system is performed using ANSYS simulation package. The objective is achieved by using ANsYS simulation packages and dynamic and static loads are applied on the suspension systems.
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 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.

TL;DR: In this paper, a detailed multi-body dynamics model for the suspension system is built to simulate forces exerted on the damper and the minimization of its lateral component is selected as the design target for the spring.
Abstract: Undesired lateral force inevitably exists in a MacPherson suspension system, which is liable to damper rod’s side wear and promotes the damper’s inner friction decreasing the ride performance from the suspension system. Substituting a new side load spring with curved centerline for the conventional coil spring has been proven able to solve these problems and Multi-body Dynamics combining with Finite Elements Analysis may be an efficient method in optimizing its design. Therefore, taking a passenger car as example, a detailed multi-body dynamics model for the suspension system is built to simulate forces exerted on the damper and the minimization of its lateral component is selected as the design target for the spring. When the structure optimization of the side load spring is performed using FEA software ANSYS, its vertical and lateral elastic characteristics, supported by test data, are analyzed. After importing FEA results back to the suspension system, the dynamics simulation can be performed to validate the optimization result.

TL;DR: In this article, a two-dimensional mathematical model of a McPherson strut setup is proposed, which considers not only the vertical motion of the chassis but also rotation and translation for unsprung mass (wheel assembly).
Abstract: Most of automobiles these days are using two suspension systems namely: double wishbone suspension system and McPherson suspension due to their good dynamic performance and higher passenger comfort. The MacPherson strut setup is still being used on high performance cars such as the Porsche 911, several Mercedes-Benz models and lower BMW models due to its light weight, design simplicity and low manufacturing cost. This paper proposes a systematic and comprehensive development of a two-dimensional mathematical model of a McPherson suspension. The model considers not only the vertical motion of the chassis (sprung mass) but also rotation and translation for unsprung mass (wheel assembly). Furthermore, this model includes wheel mass and its moment of inertia about the longitudinal axis. The paper offers an implementation of the model using Matlab- Simulink, whose dynamics have been validated against a realistic two dimensional model developed with the Ansys software.
