Abstract: Vehicle passive suspension systems require an investigation to determine the spring, mass and damper settings that assure optimal Ride Comfort (RC). In this paper, Ride comfort has been maximized by optimizing various suspension parameters using a quarter-car test rig and implementing full factorial methodology of Design of Experiments (DOE). As per ISO 2631-1:1997 standard, the ride comfort has been measured in terms of the R.M.S.....

DOI	:	10.9790/1684-1500809-14

Abstract: In this following work, distribution of stresses along the implant-bone interface is computed by performing 3D finite element analysis on commercially available dental implant system. The analysis of stresses is mainly focused at the implant-bone interface specifically at the neck region i.e. proximal zone. The effect of various thread parameters like thread pitch, and depth were studied on the stress distribution along the implant-bone interface

Abstract: At micro-level operations, to make precise microscopic movements, there is need of aalternative mechanism other than conventional mechanism like compliant mechanism. It is rapidly increasing field where a device that uses the compliance of its structure to achieve mechanical tasks such as force and motion transmission.Due to lack of available space, the new mechanisms should be compact without compromise in their accurate & precise performance. Unlike conventional mechanisms, compliant mechanism is monolithic, joint-free & elastic continua.This paper chiefly focuses on the results of variation of parameters within the design of a compliant micro-gripper that uses semi-circular hinge to transmit motion. According to the requirement of an application, the various dimensions of a micro-gripper can be varied. PRBM (Pseudo Rigid Body Model) approach is used to design the micro-gripper. This paper contains analysis work using FEA software (ANSYS).

Title	:	Experimental Stress Analysis of Hip Joint Implant for Fracture Analysis
Country	:	India
Authors	:	S. L. Gavali1, S. H. Gawande2, S. R. Patil2, R. N. Yerrawar

Abstract:Hip Joint is one of the important body parts of the human body, which transmits the body forces to the legs. Different materials like stainless steel, zirconium and titanium are used in the design of hip joint. Still the perfect material on basis of strength, cost and weight are not specified. Literature survey and expert opinion in this field state that, it is very difficult to give the exact design of implant and investigate the selection of materials, shapes, effect of vibration, and prediction of failure of implant. Hip fracture is a major cause for disability in human being.....

Title	:	Photoelastic Stress Analysis: A Review
Country	:	India
Authors	:	S.B. Shinde || Prof. S.S. Hirmukhe || Prof. P.N. Dhatrak

Abstract: Photo elasticity is whole field technique which works on the property "birefringence" of transparent material. Birefringence means transparent material shows two refractive indices before and after loading. Combined with other optical elements and with white or monochromatic light source, a loaded photo elastic specimen (or photo elastic coating applied to an ordinary specimen) exhibits different fringe patterns which are related to the principal stress difference perpendicular to plane of propagation of light. This technique is widely used in various areas including dentistry, automotive, civil and electrical field also. This review paper provides information regarding the photoelasticity technique used by the various researchers in various fields. The objective of this paper is to provide guidelines regarding use of photoelasticity for several applications in automotive, bio-engineering, electrical fields. A literature search was conducted by using keywords such as photoelasticity, stress analysis, and fringes. Among several articles and research papers, most of the articles related to photoelasticity and stress distribution were shortlisted for complete reading and data extraction. Thus, various applications of photoelasticity are viewed.

DOI	:	10.9790/1684-1500838-43

Abstract: Present trend is to design vehicles to provide maximum comfort to the driver and passenger in spite of the different road conditions. Suspension system is one of the part of vehicle which gives ride comfort. Suspension system plays major role in absorbing road vibrations and provides effective comfort to the diver as well as passenger. This paper presents performance comparison of passive and semi-active suspension system of a quarter car model for different vehicle velocities for half sine wave bump and then for different road profiles using MATLAB SIMULINK. In semi-active suspension system with Proportional-Derivative-Integrator (PID) controller is developed which gives optimal and robust system by withstanding different road conditions and vehicle speeds to increase ride comfort.
