Title: Design and Development of Novel Configuration of Steering Knuckle for an All Terrain Vehicle (ATV) Authors: Patil, A. S.; Kushare, P. B.; Modi, S.; Lad, V. Abstract: Steering knuckle or suspension upright is one of the most critical loaded parts in an automobile and especially in all terrain vehicle (ATV) as it has to sustain the forces arising from the braking torque, road bump and the steering pull. Also, in the commercial vehicles, the left knuckle cannot be interchanged with the right knuckle. Therefore there is a need of design and development of a steering knuckle which may be interchangeable and manufactured as a one piece product. Also to reduce the overall weight of an automobile a light weight steering knuckle should be designed. Thus the design and development of a low weight knuckle which is structurally rigid and has the ability to withstand all the forces arising due to bump, cornering, cyclic loading during steering and braking while being interchangeable between front wheels of an Off-Road vehicle is discussed in this article.

Title: EXPERIMENTAL INVESTIGATION AND VALIDATION OF NATURAL FREQUENCY OF RECTANGULAR PLATES AND LAP JOINTS Authors: Sonawane, A. R.; Nichit, V. D. Abstract: This paper deals with experimental investigation and validation of rectangular plates and lap joint using modal analysis. The purpose of the study is to analyze the dynamic behavior of structures like a rectangular plate, bolted lap joint, and single lap epoxy adhesive joint subjected to impact or shock loads using Finite Element Analysis (FEA) and experimental modal analysis. The various factors that affect the response of single rectangular plate, bolted and adhesive joint structures are studied, such as, mode shapes, damping ratio, natural frequencies etc. The purpose of this paper is to deliver effective techniques using software analysis for the calculation of the vibrant reply of single rectangular plate with rectangular plate lap joints and to validate the predictions by experimental modal analysis and FEA. The FEA method is used to validate the mode shapes, natural frequencies, and frequency response roles of the beams. The three different specimens are used which consist of aluminum material. The initial case study is focused on a simple rectangular plate of cantilever beam subjected to impact force. The second case study is focused on bolted lap joint and single lap adhesive joint. The core objective of this work is to determine the natural frequency and mode shape of all three specimens at cantilever beam condition and first to compare the result of all joints with the single rectangular plate and then compare it with experimental modal analysis. In practical application this kind of modal analysis can be used to analyze various structures to find natural frequency & mode shapes such as cantilever bridge, frame of bicycle, automobile product, Industrial robots (manipulator), building structures, heavy machineries and aircraft industry etc.

Title: A Review on Effect of Cryogenic Treatment on Tool Steel Authors: Dixit, N. S.; Khond, V. V.; Kavale, P. K. Abstract: Cryogenic treatment is used nowadays commonly in manufacturing various tools and instrument like forging dies. It is the type of material processing technology. Cryogenic treatment not only affects the surface of the component but it affects whole structure of component.Cryogenic treatment has been recognised that they can reduce the retained austenite and improve the performance of materials by improving its martensite structure also increase the formation of very small carbides, improving the general mechanical properties of the steels. This paper reviews cryogenic treatments involved in treating tool steel, effect of process parameters and their effect on properties.

Title: Local heat transfer for jet impingement onto a concave surface including injection nozzle length to diameter and curvature ratio effects Authors: patil, V. S. Abstract: The effect of jet nozzle length to diameter ratio on local heat transfer coefficient measurements for a row of circular jets impinging onto a concave surface for varying target spacing are reported here. The nozzle length to diameter ratio (L/d) and the nozzle to target spacing (H/d) were varied from 0.2 to 6 and 0.67 to 8 respectively. Three curvature ratios, defined as the ratio of jet diameter to target surface diameter (d/D), equal to 0.1, 0.2 and 0.3 were studied and the jet to jet pitch to diameter ratio (P/d) was kept constant at 4.0. The Reynolds number was varied between 10,000 and 50,000 and wall static pressures for some cases were measured for obtaining a better understanding of the heat transfer coefficient variations. Higher stagnation zone Nusselt numbers were observed for the jet nozzles with small L/d at small H/d values whereas at larger H/d values nozzle length was observed to affect the data only marginally. The difference between Nusselt number values, between H/d = 2 and H/d =8, was observed to progressively reduce with increasing L/d ratio and this was true for both the local stagnation point as well as the spanwise averaged stagnation line values. The maximum local Nusselt number values were observed to shift from the geometric impingement location to nearby locations for very small nozzle diameter to target distance ratios (H/d≤ 1) for larger curvature ratios. A constant heat transfer impingement area with constant pumping power criterion is presented to compare the performance of the different configurations studied. The longer nozzle lengths and smaller curvature ratios are observed to perform better based on this criterion. A correlation is presented for the overall averaged Nusselt number, with a validity within the parameter range studied, with a±10% error band
