“…It is very simple, flexible, inexpensive, suitable for mass production and uniform distribution of reinforcement particles can be achieved by stirring action (Saravanan et al , 2017a, 2017b). Lata et al (2018) investigated that the mechanical properties of AA5051-TiO 2 metal matrix composite (MMC) produced by stir casting route and reported that the strength and hardness of the composites increases with the incorporation of TiO 2 particles. Roussos (2014) produced aluminium alloy Al6061 hybrid composites reinforced with TiO 2 and graphite particles through the stir casting route and concluded that the hardness and tensile strength of composites were gradually improved with increasing the reinforcements in the base alloy.…”

Purpose Aluminium and its alloys are the most preferred material in aerospace and automotive industries because of their high strength-to-weight ratio. However, these alloys are found to be low wear resistance. Hence, the incorporation of ceramic particles with the aluminium alloy may be enhanced the mechanical and tribological properties. The purpose of this study is to optimize the specific wear rate and friction coefficient of titanium dioxide (TiO2) reinforced AA7075 matrix composites. The four wear control factors are considered, i.e. reinforcement (Wt.%), applied load (N), sliding velocity (m/s) and sliding distance (m). Design/methodology/approach The composites were fabricated through stir casting route with varying weight percentages (0, 5, 10 and 15 Wt.%) of TiO2 particulates. The mechanical properties of the composites were studied. The specific wear rate and friction coefficient of the newly prepared composites was determined by using a pin-on-disc apparatus under dry sliding conditions. Experiments were planned as per Taguchi’s L16 orthogonal design. Signal-to-noise ratio analysis was used to find the optimal combination of parameters. Findings The mechanical properties such as yield strength, tensile strength and hardness of the composites significantly improved with the addition of TiO2 particles. The analysis of variance result shows that the applied load and reinforcement Wt.% are the most influencing parameters on specific wear rate and friction coefficient during dry sliding conditions. The scanning electron microscope morphology of the worn surface shows that TiO2 particles protect the matrix from more removal of material at all conditions. Originality/value This paper provides a solution for optimal parameters on specific wear rate and friction coefficient of aluminium matrix composites (AMCs) using Taguchi methodology. The obtained results are useful in improving the wear resistance of the AA7075-TiO2 composites.

“…The tensile strength of 238 MPa had been achieved, which was 11% higher than pure Al alloy as shown in the Figure 5. Lata et al [44] also opted stir casting route for the fabrication of Al7075-TiC (5, 10 and 15 wt. %) MMC and determined its tensile strength which had increased due to the uniform dispersion of TiC particles.…”

In this 21st century, various materials like metals, alloys, and composites are available for different industrial applications. Composite materials are gaining popularity due to their enhanced mechanical properties over other materials. However, for continuous improvement in the properties of these materials, different research groups are constantly inVolved in it. In this research paper, the focus is to review the mechanical properties like hardness, tensile strength, flexural strength, impact strength along with surface characteristics like wear resistance of AMMC's. As per the available literature, liquid state processing is more popular than solid-state processing due to the better dispersion of the reinforcement particles in the matrix materials. Stir casting is mostly used liquid state processing method because of its ease and the overall low cost of production. It has been noticed that the mechanical and surface characteristics of AMMC's can be improved by adding different reinforcement particles in small percentages (usually 0.5-20%). It has been observed that hardness, tensile strength, and flexural strength for mostly used AMMC's ranges from MPa respectively. This research paper also included the influence of various working parameters on the wear rate of AMMC's. It is noticed that wear loss for AMMC's generally varies from 0.0050-0.004 g. The impact resistance is a crucial parameter in the study of AMMC's used for aerospace and automotive applications and it has been noticed that its value for popular AMMC's varies from 3.6-38 J.

“…The front suspension system consists of a system of short-long arm directly actuated double wishbone suspension. This type of suspension is used because of the length of the upper and lower arms, vertical suspension movement results in an increase in negative camber [3]. This means that the tires on the outside of a turn stay in better contact with the road, because the negative camber gain that occurs as the body roll helps make sure that the contact patch of the tire is as large as possible.…”

Suspension is a system of tires, springs, shock absorbers, and linkages that connects a vehicle’s chassis to its wheels and allows relative motion between the two. Steering is a mechanism that provides a direction to the vehicle, it basically consists of gears, shaft, joints, steering column, steering wheel, and furthermore. The main objective of this paper is to design a system of suspension and steering for a three-wheeled human-electric hybrid trike. A system of directly actuated double wishbone suspension system is chosen for the front and a pushrod actuated 2-link trailing arm suspension system for the rear. The steering system used is a type of Single tie rod and drag link system. A knuckle-to-knuckle drag link provides continuity to the wheels and a tie rod to the bell crank provides steering rotation. This paper also talks about the single nut hub-shaft system which is being used in the front suspension system. Based on the research using various input parameters, the inboard and outboard suspension hardpoints are decided to maximize the tire contact patch at every vehicular motion (mainly during body roll). Forces and stresses are calculated with the help of Free Body Diagrams (FBD) and Multi-Body Dynamics (MBD) software LOTUS Shark. The paper discusses the calculations regarding the roll and ride rates and for the custom springs of specific stiffness used in front and rear shock absorbers and the variation of roll steer and bump steer on changing various parameters of the steering system. Key points also include the procedure of selections of various types of bearings, rod ends, and bolts. This paper also talks about laser-cut jigsaw uprights that are used in the front wheel assembly. The finite element method was used to analyze the designs using DS Solidworks and Ansys Workbench. Static structural and explicit dynamics analysis was performed on the wheel assembly components both individually and assembled
