It discusses previous research on ATV chassis design that focused on structural optimization, weight reduction, and stress analysis using finite element analysis. The document then outlines the objectives, methodology, and literature review of the project to modify an existing ATV chassis design. The goals are to reduce weight, increase strength, and modify the old design. CAD software will be used to model and simulate the new design, which aims to improve handling, maneuverability, and cost-effectiveness while meeting competition requirements.
IRJET- Design and Analysis of Suspension System, Brakes and Wheel Assembl...IRJET Journal
This document describes the design and analysis of the suspension system, brakes, and wheel assembly for an all-terrain vehicle (ATV). Key aspects of the design included improving vehicle handling, increasing ride height and wheel travel, and improving component durability. Suspension and brake systems were analyzed using Solidworks and Lotus simulation software. Design objectives such as performance, safety, manufacturability, and cost were prioritized. The suspension utilized double wishbone design with parameters like camber and castor optimized. Brake calculations were performed to select the master cylinder and calipers. The wheel assembly was designed to reduce unsprung mass while maintaining performance.
The document discusses the design and optimization of a B pillar trim component for automobiles using nonlinear finite element analysis (FEA) and dent testing. It provides background on pillar trims and B pillar trims specifically. The objectives are to computationally design and experimentally test different B pillar trim designs with varying stiffener patterns and materials to improve strength-to-weight ratio. The methodology involves CAD modeling, nonlinear FEA, design iteration, 3D printing fabrication, and dent testing validation. Progress includes understanding rib features, initial CAD modeling, material selection, and reverse engineering of an existing design.
IRJET- Review of Optimization Aspects for Weight ReductionIRJET Journal
This document summarizes a review paper on optimization methods for weight reduction. It discusses how topology optimization and composite optimization are two important processes used for weight optimization. Topology optimization uses finite element analysis and other simulation methods to optimize the layout of material within a design space to reduce weight. Composite optimization focuses on optimizing composite materials to reduce weight. The review discusses various studies that have applied topology optimization techniques to automotive, aircraft, and mechanical component designs to reduce weight and improve performance. It also outlines some challenges with optimization methods and how computational tools are helping to optimize designs.
1) The document presents the design and analysis of a brake component for a vehicle. It aims to optimize the design to reduce weight while maintaining strength.
2) The brake disc is modeled in SOLIDWORKS and analyzed in ANSYS for static and thermal loads. Calculations are presented for deceleration, stopping time, weight distribution, and required braking forces.
3) A hexagonal lattice structure is used to optimize the CAD model of the brake pedal to reduce weight, inspired by honeycomb structures. Static structural analysis is performed and stresses are evaluated.
Static Analysis of the Roll Cage of an All-Terrain Vehicle (SAE BAJA)IRJET Journal
This document summarizes the static structural analysis of the roll cage for an all-terrain vehicle conducted by Shivam Mishra. The analysis was performed using ANSYS Workbench to simulate various collision scenarios, including front, rear, side impacts and rollovers. The roll cage was designed and modeled in Solidworks considering factors like safety, manufacturability, and weight. A finite element analysis was then conducted in ANSYS to analyze von Mises stresses and deformations. The results showed safety factors above 1 in all tests, confirming the roll cage design can withstand impacts while remaining lightweight.
Development of a Model for the Simulation of ROPS Tests on Agricultural Tract...IJERA Editor
It is here proposed a methodology for simulation of ROPS tests (ROPS = Roll Over Protective Structure) of
agricultural tractor cabins. The work is based on the resolution of this problem through the use of the finite
element method. In order to limit the number of nodes of the model and thus to speed up the resolution,a twodimensional
finite elements model has been chosen. The method presented here solves with relative ease, even
very complex structures. There are also simplest methods in literature where specially made software is based
on the finite element method for simulating approval tests on ROPS structures. In this case,codes developed just
for this purposeare available, and therefore very simple to use and characterized by a high speed of preparation
of the model following the definition of a small number of parameters. On the other side these are codes
designed for structures having a specific geometric shape and in which the user is not free to set all the
parameters existing in commercial software for the structural calculation, and are not very suitable in case of
complex or not conventional structures. The methodology proposed by the authors instead, although not
automated, allows simulating any type of structure in acceptable times. The results were validated by full scale
experimental tests. Through the interpretation of the results it is possible to identify which areais the most
critical for the structure and evaluate any change, something which is not easy to do through expensive tests.
IRJET- Design and Frontal Crash Analysis of FSAE BAJA Roll CageIRJET Journal
1. The document discusses the design and analysis of a roll cage for a Formula Student race car. Computer-aided engineering tools like SOLIDWORKS and Autodesk were used.
2. A space frame chassis made of 4130 alloy steel was designed and analyzed. Load cases like horizontal loading, longitudinal torsion, vertical bending, and lateral bending were considered.
3. The design requirements focused on meeting competition rules as well as providing adequate structural strength, stiffness, crashworthiness, and ease of manufacture. Computer simulations were performed to analyze the torsional stiffness of the design.

Topology Optimization of Student Car Steering KnuckleIRJET Journal
This document describes topology optimization work carried out to reduce the weight of a student car's front steering knuckle. The researchers performed CAD modeling and finite element analysis of the original knuckle design. They then applied topology optimization techniques in ANSYS Discovery to iteratively reduce the knuckle's weight without exceeding stress or deformation limits. This resulted in a weight reduction of up to 8% (344.2 grams) from the original 4,302.51 gram design, with the optimized knuckle weighing 3,958.31 grams while still meeting all structural requirements under simulated loading conditions. The researchers concluded that topology optimization is an effective method for designing lightweight parts like steering knuckles without compromising performance.

CONCLUSIONS
The implementation of assembly fixture in a car engine assembly line has significantly reduced
the injury possibility during assembly tasks
The implementation of assembly fixture has reduced the posture score assessed using OWAS
method by 31%, while RULA method shows that the posture performed are cut down by 42%
Performing car engine assembly processes without the use of an assembly fixture have several
negative outcomes, especially to the trunk, arms, and neck of the worker
Unfortunately, the assembly fixture in PT. XYZ has not yet fully resolve the ergonomic of the
upper limb (the scores are still marked yellow, which means that it needs to be evaluated)
Implementation of an assembly fixture can reduce the complexity and increase accuracy by
optimizing PC speaker assembly process
