Fatigue Life Analysis

This paper presents fatigue life analysis of high performance motorcycle disc brake. The design parameter such as stress, deformation and safety factory that influences the disk brake on a high performance motorcycle were investigated. The simulation of static structural analysis of high performance motorcycle is successfully presented on 3 proposed materials by using ANSYS software. The static structural analysis is performed on the disc brake rotor with these candidate materials. From the analysis, Martensitic stainless steel, Wrought AISI 410 has the lowest value in Von-Mises stress which is 766.9MPa. Furthermore, it is less deformed which is 0.3429mm and has the factor of safety more than 1. Thus, this project proposes Martensitic Wrought AISI 410 stainless steel as the suitable material for disc brake rotor on HONDA GL1500 VALKYRIE motorcycle.

Brakes are the most important component of any automobile. Brakes provide the ability to reduce or bring automobile to a complete stop. The process of braking is usually achieved by applying pressure to the brake discs. The main objective of this research paper is to propose an appropriate design and to perform analysis of a suitable brake rotor to enhance the performance of the high-speed car. The design of the brake disc is modelled using Solid works and the analysis is carried out using Ansys software. The analysis has been conducted by considering stainless steel and grey cast iron using same brake rotor design so that optimal choice of brake disc can be considered. The analysis considered involves static structural analysis and steady state thermal analysis considering specific parameters on brake rotor to increase the life of brake rotor. From the analysis it is found that the performance and life of disc brake depends upon heat dissipation. From the analysis results it can be concluded that grey cast iron has performed better as compared to stainless steel as this material has anti-fade properties which improves the life of the brake rotor.

The last decade has seen the rapid advancement of nanofluid in several ways. Nanofluid based on the refrigerant have been introduced as nanorefrigerant in recent years due to their significant effects on the efficiency of heat transfer. Previous studies showed some limitation in ways of dispersing nanoparticles into refrigerant. Hence, a new idea of adding nanoparticles into refrigerant has been presented. A mixing chamber has been designed to mix nanoparticles into high pressure refrigerant. The mixing chamber design is drawn with five different wall thickness which are 2 mm, 4 mm, 6 mm, 8 mm and 10 mm to investigate the sturdiest design that can withstand high pressure. Static structural analysis is performed to all designs with different wall thickness on SolidWorks Simulation. The maximum values of von Misses stress and displacement has been presented in this paper. Validation of the results are made by comparing the maximum values of von Mises stress with yield strength of the material. Mixing chamber with wall thickness of 10 mm showed the best results.

Deep soil loosening machine MAS 65 is destined to work soil at depths exceeding 45 cm, thus the machine’s frame is subjected to loads which could affect its structural integrity. Within this paper a static structural analysis was performed on the machine’s 3D model using finite element method and strain and stress distribution maps were created. Using the Von Mises stress map there were identified several critical points which could fail during normal exploitation conditions and which should be monitored by strain gages during field tests in order to prevent structural failure.

In this work, numerical simulations of the transient thermal and the static structural analysis were performed here sequentially, with the coupled thermo-structural method. Numerical procedure of calculation relies on important steps such that the CFD thermal analysis has been well illustrated in 3D, showing the effects of heat distribution over the brake disc. Three different brake disc materials were selected in this simulation and a comparative analysis of the results was conducted in order to derive the one with the best thermal behavior. Finally, the resolution of the coupled thermomechanical model allows us to visualize other important results of this research such as; the deformations, and the equivalent Von Mises stress of the disc, as well as the contact pressure of the brake pads. Following our analysis and the results we draw from it, we derive several conclusions. The choice allowed us to deliver the best suitable of the brake rotor to ensure and guarantee the good braking performance of vehicles.

Background:The femur bone is an essential part of human activity, providing stability and support in carrying out our day to day activities. The inter-human anatomical variation and load bearing ability of humans of different heights will provide the necessary understanding of their functional ability.Objective:In this study, femur bone of two humans of different lengths (tall femur and short femur) were subjected to static structural loading conditions to evaluate their load-bearing abilities using Finite Element Analysis.Methods:The 3D models of femur bones were developed using MIMICS from the CT scans which were then subjected to static structural analysis by varying the load from 1000N to 8000N. The von Mises stress and deformation were captured to compare the performance of each of the femur bones.Results:The tall femur resulted in reduced Von-Mises stress and total deformation when compared to the short femur. However, the maximum principle stresses showed an increase with an increase in the bone length. In both the femurs, the maximum stresses were observed in the medullary region.Conclusion:When the applied load exceeds 10 times the body weight of the person, the tall femur model exceeded 134 MPa stress value. The short femur model failed at 9 times the body weight, indicating that the tall femur had higher load-bearing abilities.
