Abstract: In this paper, a brief introduction to vehicle primary suspension system is presented along with analysis of a semiactive suspension system with Bingham model for MR damper.Isolation from the forces transmitted by external excitation is the fundamental task of any suspension system. The heart of a semiactive suspension system is the controllable damper. In this paper, the ride and handling performance of a specific vehicle with passive suspension system is compared to semiactive suspension system. The body suspension wheel system is modeled as a two degree of freedom quarter car model. Simulation is carried out using MATLAB/Simulink. The developed design allows the suspension system to behave differently in different operating conditions, without compromising on road-holding ability. Controller has been developed for semi active suspension. The result shows improvement over passive suspension method.

Title	:	Application of Value Stream Mapping Tools For Process Improvement a Case Study in Foundry
Country	:	India
Authors	:	Mr.Girish.C.Pude1, Prof.G.R.Naik2, Dr.P.G.Naik

Abstract: A value stream is all the actions (both value added and non-value added) required to bring a product through the main flows essential to every product for the production flow from raw material into the arms of the customer and to design the flow from concept to launch as a lean manufacturing tool. Taking a value stream perspective means working on the big picture, not just individual processes and improving the whole not just optimizing the parts. In this paper three case studies in xyz foundry with results are considered with current state maps and future state maps after following the different steps starting from the detailed time study for mapping the processes from raw material to final product. According to VALSAT (Peter Hines & Nick Rich) three tools namely Process activity mapping, Quality filter mapping and Production variety funnel have shown greater effectiveness to reduce the wastes in foundry. Process activity mapping is a Value stream mapping tool has its origins in industrial engineering. Production Variety Funnel is a Value stream mapping tool has its origins in Operations management. Quality Filter Mapping is a new Value stream mapping tool specially used to focus on the defects produced relating to the physical products.

Keywords- Current State map, Future State Map, Process activity mapping, Production variety funnel, Quality Filter Mapping.

Abstract: There are several categories of CVTs in existence today, including traction, belt, and ratcheting types. Drives of these types, their attributes, and associated design challenges are discussed to frame the development of the Cam-based IVT. The operation of this transmission is kinematically similar to a planetary gear set, and therefore, its operation is described with that in mind including a description of the six major components of the transmission, those being the cam, followers, carriers, planet gears, sun gears, and one way clutches. The kinematic equation describing its motion is derived based on the similarities it shares with a planetary gear set. Additionally, the equations for the cam design are developed here as the operation of the CVT is highly dependent on the shape of the cam. There are six simple inversions of this device and each inversion has special characteristics and limitations, for example, the available gear range. A method was developed to select the most suitable inversion, gearing, and follower velocity for a given application.

Country	:	India
Authors	:	Mr. KARTIKA S.B1, Mr. ARAHANTH

Abstract: Potato chips and other snack foods. It accounts for Overall turnover: $ 2.2 billion dollars from 70 manufacturing and technology research centers on the world. For the year 2010-2011.Problems with current Indian chip manufacturers are the wastage of vegetables and uneven thickness of the slices resulting in the low quality and there is a productivity loss in the manufacturing of chips in the Indian market due to non availability of the proper tools. The chips makers are at the risk of injuring their fingers and having difficulty in producing the type of slices they wanted. In hotels cucumber, onions and carrots all are sliced in a different thickness and also it requires a skilled worker to slice them evenly. The present work focuses on design and development of an improved version of a portable potato slicer that takes care of the problems mentioned above.

Title	:	Experimental Verification of Passive Quarter Car Vehicle Dynamic System Subjected to Harmonic Road Excitation with Nonlinear Parameters.
Country	:	India
Authors	:	Prof. S. P. Chavan1, Prof. S. H. Sawant2, Dr. J. A. Tamboli

Abstract: Vehicle dynamic analysis has been a hot research topic due to its important role in ride comfort, vehicle safety and overall vehicle performance.. For proper designing of suspension system, nonlinearities in suspension parameters must be considered. In this paper, nonlinearities of spring and damper are considered while preparing quarter car model. For this a simplified model and experimental set up for the same is developed. The deterministic impulses due to road profile are given by harmonic shaker which gives input motion to shock absorber. The sprung mass acceleration response obtained by FFT analyzer at sprung mass of quarter car model is compared with the results obtained by linear and nonlinear MATLAB Simulink models.

Title	:	Microchannel heat sink fabrication techniques
Country	:	India
Authors	:	Prof.V.P.Gaikwad

Abstract: Heat fluxes in IC chips and other electronics equipment have reached the current limits of air cooling technology. Some of the applications require heat fluxes well beyond the limit of 100 W/cm2, requiring advanced cooling solutions. This paper provides a roadmap of development in the thermal and fabrication aspects of microchannels as applied in microelectronics and other high heat flux cooling application. The formation of a monolithic microchannel heat sink and its performance is also discussed.

Title	:	NUMERICAL SIMULATION OF MULTI-CHAMBER PISTON C.I ENGINE
Country	:	India
Authors	:	Mr. ARAHANTH 1, Mr. KARTIKA S.B

Abstract: Due to increase in the demand and the scarcity in the availability of the fossil fuels, it is essential to search for the effective burning of fuel in the existing system. In diesel engines the fluid motion within the engine cylinder is one of the major factors that controls the fuel-air mixing, combustion processes and also has a significant effect on heat transfer. Both the bulk gas motion and the turbulence characteristics of the flow are important for the performance of C.I engine. The present work relates to the modification of the C.I engine design for inducing turbulence by squish and tumble flows to improve the combustibility of the combustible mixture. This modification includes the formation of multi-chambers on the piston crown. It consists of three small chambers at 120º apart. The C.I engine with multi-chamber piston at motoring condition has been analyzed through C.F.D using fluent software and the results obtained are compared with the base C.I engine.

Keywords: piston crown, performance, squish, turbulence, tumble.
