Title : Performance Evaluation of Active Suspension for Passenger Cars Using MATLAB
Country : India
Authors : K. S. Patil, Vaibhav Jagtap, Shrikant Jadhav, Amit Bhosale, Bhagwat Kedar

Abstract: The aim of this study are to obtain a mathematical model for the passive and active suspension systems for quarter car model and construct an active suspension control for a quarter car model subject to excitation from a road profile using PID controller. Current automobile suspension systems using passive components only by utilizing spring and damping coefficient with fixed rates. The purpose of the suspension system is to improve passenger comfort while providing good road handling characteristics subject to different road profile. Passive suspensions only offer compromise between these two conflicting criteria. Active suspensions possess the ability to reduce the traditional design as a compromise between handling and comfort by directly controlling the suspensions force actuators. In this study, the active suspension system is proposed based on the Proportional Integral Derivative (PID) control technique for a quarter car model for the enhancement of its road handling and comfort. Comparison between passive and active suspensions system are performed by using road profile as an input. The performance of the active suspension system is evaluated by comparing it with passive suspension system. The performance of these will be determined by performing computer simulations using the MATLAB and SIMULINK toolbox. The simulation is enhanced with 3-D animation of car going on bump created in VRML. Keywords - Active suspension system, PID Controller, Simulink, Quarter car model, Virtual reality animation

Title : LCD based Micro – Stereolithography: A Novel Technique for Rapid Prototyping
Country : India
Authors : B. K. Suryatal, S. P. Deshmukh

Abstract: The LCD based Micro stereolithography (μSLA) can be developed to produce highly precise, three-dimensional (3D) microstructures from broad selection of functional materials, especially bio-compatible materials. In principle, μSLA utilizes focused light to scan over the surface of a photo-curable resin, which undergoes photo-polymerization and forms solid microstructures. It provides an engineering platform for various applications, such as Microelectromechanical Systems (MEMS), integrated photonics, tissue engineering, and Tetra hertz (THz) metamaterial synthesis. The μSLA fabricated devices, containing complex engineered microstructures which are covered with self-assembled functional groups, can work as a unique interface between the nanometer scale functional group and macro-scale bio-medical samples, therefore can find applications in Bio-MEMS. The basic concepts of LCD based Micro stereolithography and a case study of manufacturing a bevel gear using photosensitive resins reinforced with ceramic nanoparticles is presented in this paper.

Country : India
Authors : S. J. Pal, P. Muthu, A. D. Muhuri

Abstract: CT scan is a basic and very important tool for medical diagnosis. But if we can build a physical model from CT scan data then it can be a very useful tool for medical diagnosis and several medical simulations. This article surveys a promising approach to computer assisted image medical image analysis technique. This analysis combined with extracting the data from CT scan, segmentation and building a 3D physical model from the virtual CT scan data. We have priority knowledge about the size, shape and the location of biological structures. But there is a significant variability of biological structures over time and across different individuals. So these patient specific models will help medical physicians to interpret with the disease more prominently. These CAD model also can be simulated with any fluid-structure interaction analysis and the behaviour of fluid flow san be estimated through this diseased biological organ. In this study a complete methodology, from acquisition of medical images to building the three dimensional model with a particular emphasis on image segmentation was studied. In this study we have developed a 3D CAD model of female Lower Urinary Tract (LUT.

Title : Design and Analysis of Barrel Coupling
Country : India
Authors : S. S. Bari, D. H. Burande, M.R. Birajdar

Abstract: The A Barrel coupling system is the method of choice in transferring torque between rotating parts. The torque load is acting axially along the centreline of the shaft. The challenge in coupling design lies in Finite element structural analysis which leads to better results than current classical practices, because it permits a more accurate representation of the true structure. In this paper factors affecting on barrel coupling size like the Nominal transmission torque and Radial load are discussed. The methodology employed in this work will subsequently used to carry structural rigidity under load conditions. The emphasis in the work will be placed mostly to use a finite element method. Barrel Coupling was modeled in Catia V5 CAD software and analysis of this was done by using ANSYS work bench. The analysis of barrel coupling has been done by fixing different components of assembly, with application of radial force and transmission torque. We have found out stresses and deflection occurred in the barrel coupling.

Country :  
Authors : M. A. Nalawade, S. H. Dwivedi, K. R. Kapadni, A.V.Waikar, S. H. Gawande, R. N. Yerrawar, U.B. Ubarhande

Abstract: Conventionally heat exchangers are designed using either ASME code or TEMA standards for the given design conditions. This design ensure the safety, however the stresses at typical locations, such as a Kettle type conical shell and in the vicinity of nozzle reinforcement pads, are not easy to locate and evaluate. Hence, in this work a simplified approach to locate the position of nozzle opening for kettle type STHE is presented. This paper focuses on the analysis of eccentric cone which is welded with the shell on both sides with the nozzle. During analysis it is observed that stress peak is lying in the close vicinity of the nozzle opening. The detailed design, analysis, fabrication and testing work was carried out at Alfa Laval (India) Pvt. Ltd., Pune-12.

Title : Optimization of an Error due to Non-Perpendicularity of optical axis of Digital Microscope with the plane of Micro machine Base
Country : India
Authors : G. K. Jain, A. A. Agarwal, A. M. Dalavi

Abstract: Errors are introduced in Micro machining processes due to various types of External physical effects. One of the major effects often taken into consideration is known as Non-Perpendicularity. When we need to find offset between two or more movable attachments or tools on the machine, error may occur due to non-perpendicularity of the respective planes of tool and base and as a result we get approximated value of offset. This paper is made on the work of optimization of this error by developing a Mathematical Model so as to obtain precise results. The perpendicularity of the camera's optical axis to the surface being observed is one of the basic conditions for the validity of the measurement. Small magnitudes of camera misalignment angles, up to two or three degrees can go easily unnoticed during the initial setting of the experimental setup especially when the stand-off-distance between the camera and the surface is not small.

Title : Efficient Wall Thickness Analysis Methods for Optimal Design of Casting Parts
Country : India
Authors : N. A. Patil, A. P. Deshmukh

Abstract: Wall thickness is an important parameter for casting design. Thin wall sections cause breakage of parts during manufacturing or during usage of the part. Thick wall sections cause problems in castings and increase weight, needs more material thus increasing the cost. Optimal wall thickness is also important for adequate and sufficient strength of parts. The current process of wall thickness measurement involves taking sections of the design along standard axis and then measuring those sections using tools available in Computer Aided Design (CAD) Software. Designers use these methods to measure wall thickness. It takes couple of week's time to analyze a complete casting for power train parts. Moreover, the process is not accurate and error prone. Most of these errors may be detected during simulation and analysis phase. This phase is a complex and time consuming process. Also it requires specialized knowledge to use these software's. In this paper, we describe an easy and efficient process related to wall thickness check for power train design, where design checks are performed in an automated fashion by the designer. This helps to correct many of the defects arising out of the wall thickness of the model. By providing this process right at the design stage, valuable time and effort is saved. Also high quality of the part guaranteed right at the design stage.
