“…Disc surface was prepared by the first surface grinding and then lapping (R.C. Singh et al,2016). Surface roughness was checked by a stylus surface roughness tester at a radius of 20,30,40,50,60 and 70 mm in the circumferential direction and 60 degrees in radial directions from a reference line.…”

Scientists are working on the development of materials and lubricants to reduce friction as well as wear at metalto- metal interfaces having relative motion. Aluminum is a widely used metal due to its high strength to weight ratio and availability in nature as compared to other metals that are manufactured by the rolling process. The output of the product quality and quantity from the rolling process requires less energy as compared to other manufacturing processes. A tribological study has been carried at the in-situ condition for the interface of Al6061 and steel EN31 on the pin on disc setup. To analyze the effectiveness of lubricant with mating surfaces, the effect of rolling lubricant was analyzed for tribological behavior and compared with the dry condition. The coefficient of friction was reduced up to 80% and the specific wear rate was reduced up to 96% by using rolling lubricant compared to dry conditions at the interface of metals that had relative motion.

Purpose In this study, the tri-bological behaviour of the un-coated and diamond coated tungsten carbide was evaluated using the pin-on-disc test rig. The same was also tested on a lathe machine tool. This paper aims to compare the tri-bological behaviour of coated tungsten carbide pin with un-coated tungsten carbide pin it also correlates the wear obtained from the two machines used. Design/methodology/approach Experiments were performed using L8 orthogonal array and results obtained on a pin-on-disc test rig under dry sliding process were optimized through a modern optimization technique i.e. genetic algorithm (GA). The response surface methodology model (L8 orthogonal array) formed the basis for the development of the GA model, which defines the conditions of minimum wear, minimum coefficient of friction and minimum surface roughness for the sliding process of the pin-on-disc test rig. Findings Implementation of the heuristic approach for optimization of input parameters for the combination of tool material used for the turning process. The initial approach involves tri-bological testing considering the same combination. The set of experiments further performed, inferred that the results were similar and that the diamond coating enhances the life of the tool. Originality/value Successfully synthesized the diamond coating on tungsten carbide tool material. Implantation of the heuristic approach, i.e. GA to tri-bological tests to identify the optimized level of input variables. Experimentation involves the tri-bological testing whose results were confirmed through performing experiments on the lathe machine tool.

“…Spindle experiences maximum force during cornering, due to lateral acceleration. The following calculations have been performed considering this case [20][21][22][23]. The minimum diameter of the designed spindle would be 14.2mm and with respect to bearing selection and availability is taken as 15mm.…”

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
