Modelling, FEA analysis and Optimization of Mono Composite Leaf Spring Using ANSYS

Conventional leaf spring made up of conventional materials like plain carbon steel are heavy and add weight to vehicle which reduces mileage. This necessitates new material which is light in weight and could provide adequate strength to leaf spring along with higher strain energy absorption to absorb shocks. The current research is intended to study the structural and vibrational characteristics of leaf spring made of P100/6061 Al, P100/AZ 91C Mg and structural steel materials. The investigation is carried out using ANSYS FEA software. The FEA results have shown that P100/AZ/ 91C generated lower stresses as compared to P100/6061 Al and structural steel material. The modal analysis of leaf spring aided to determine mass participation factor and mode shapes corresponding to each frequency.

SHIFTER MECHANISM DESIGN FOR FSAE MOTOR SPORTS VEHICLE JCU

This report provides a design analysis of a replacement’s shifter mechanism for the 2014 model JCU Motorsports FSAE vehicle. Common FSAE shifter mechanisms were researched and reviewed to provide a better understanding of the needs required. A design approach was constructed to ultimately design a mechanism that conformed to all existing constraints and FSAE rules. Realistic load cases were identified and employed in the FEA analysis of the design. Supporting hand calculations were developed, proving the analysis to be accurate. Results showed the shifter mechanism does not fail under infinite life, with some parts of the design having a reasonably high safety factor, ensuring stability.

Design, Analysis and Development of Digging and Roller Chain Conveying System for Self-Propelled Onion Harvester

The history of Agriculture in India dates back to Indus Valley Civilisation. India ranks second worldwide in farm outputs. As of 2018, agriculture employed more than 50% of the Indian workforce and contributed 17–18% to the country's GDP. India has the largest net cropped area, followed by the US and China, yet mechanization in farming is comparatively low compared to developed countries. The lack of technological development and unaffordability of new and competent machines for the average farmer are the few of the reasons for this encumbrance. The development of the onion harvester intends that it will provide a reliable and affordable alternative to traditional farming practices. The digging and conveying systems are the integrated part of the onion harvester. The design of the blade and conveyor is made by using CATIA V5 and analysis of the parts are done using ANSYS Workbench. During design and analysis, severe factors are considered such as preventing the damage to onion bulbs, size of bulbs, soil condition, onion leaves at a predetermined height and roots of the crops to penetrate. This paper is intended to discuss the results of the design and analysis of the digging and conveying systems under the guidelines of the SAE TIFAN rulebook [1]. Keywords: Onion Harvester, Blade Design, Conveyor Design, FEA Analysis.

Product Re-Engineering by Topology Optimization for Forged Component

Optimization tools are used when a set of objectives is used to find the best alternative proposed design. Topology optimization adds a whole new level of process of developing creative design space. The objective of topology design is to obtain a material distribution inside a given design space that is optimum in this aspect. Material is rearranged and elements that are not necessary from an objective point of view are eliminated throughout the optimization process. For Topology optimization of the forged component which is selected from industry which is steering knuckle assembly is optimized and presented in this study. For topology optimization, platform such as 3D experience is used to simulate the part. A number of modules from 3D experience is used for FEA analysis, mesh-smoothening techniques and creating parametric geometry in terms of shape and explored in way to produce the topology geometry more functional. Functional Generative Design module is used for topology optimization. From this study overall weight reduction is achieved after using the finite element method to analyze a steering knuckle assembly and performing topology optimization. And the part is optimized in terms of shape and for further suitable manufacturing process. According to the result of this research, 64% relative weight reduction is achieved in respect to a given target is 50%. The original weight of the knuckle was 843 gm. however it has since been reduced to 513 gm. As a result, the cost of knuckle is lowered.

Failure Analysis and Optimization of the Tie Rod Using FEA

A car’s steering wheel is used to connect the steering gear which is connect to the wheels via the tie rod ends. The main use of the tie rod end is to ensure the wheels are aligned. Hence the functioning of tie rod is crucial for steering as well as suspension performance of vehicle. Today’s world is competitive with respective to efficiency as well as economical in price, every organization striving for cost effective product at a lower price and within minimum period for ‘time to market. In this work, an attempt is made on optimization of the tier rod through changing materials and to reducing the weight.
