Air quenching is a common manufacturing process in automotive industry to produce high strength metal component by cooling heated parts rapidly in a short period of time. With the advancement of finite element analysis (FEA) methods, it has been possible to predict thermal residual stress by computer simulation. In Part I of the research, it was shown that heat transfer coefficient (HTC) for steady air quenching process is time and temperature independent but strongly flow and geometry dependent. These findings lead to the development of enhanced HTC method by performing CFD simulation and extracting HTC information from flow field. The HTC obtained in this fashion is a continuous function over the entire surface. In this part of research, two patching algorithms are developed to divide entire surface into patches by HTC profile and each patch is assigned a discrete HTC value. Performance comparison of patching algorithms is also studied.

Due to its unique physical properties (high thermal and electric conductivity) copper is one of the most interesting materials in point of view of additive manufacturing in particular of Selective Laser Melting (SLM). But because of the low laser radiation absorption, low melting point and high thermal conductivity it is difficult to fabricate of copper components without pores. Results of many research have been shown that for successful Selective Laser Melting of copper powder is needed high laser power (more than 300 W) and high laser scanning speed (more than 600 mm/s). However now most SLM machines are equipped with laser plants with output power up to 200 W. In this research, SLM machine with 200 W maximum power CO2 laser has been used. For determination of the influence of SLM process parameters on quality of copper parts rectangle specimens have been fabricated.

The diesel-powered vehicles are used widely and longer in the transportation, especially the common rail injection system. Its technology can improve the weakness of the old diesel injection system in case of emission, fuel economy and engine noise. Thus, precise fuel injection is important that manufacturer needs to consider, because inaccurate production might directly affects on the fuel injection quantity in combustion process. In the design of nozzle injector, cone angle and roughness surface of nozzle body and needle seat areas are the key that will affect to the amount of fuel. The seat dimensions of the nozzle piezoelectric injector are studied with reference to cone angle difference and roughness surface both of the nozzle body and needle seat areas under the four injection pressure test points; 1600, 1500, 900 and 400 bar for understanding about the effect on fuel injection quantity based on current production by using statistic tool.

Abstract Automotive textile is an integral aspect of technical textile. Seating fabric plays an important part in defining the interior theme in a car cabin which is being perceived by a customer. Aesthetic appeal in a fabric is achieved by interlacing/interlooping of yarns. Monofilament yarns are used to enhance the aesthetic appearance of the fabric for creating high low effect. This study involves the importance of monofilament yarn at fabric and seat trim levels in automotive seating application. Monofilament in fabric imparts aesthetic and strength to the seat trim. Apart from design & engineering evaluation, manufacturing feasibility for evaluation of fabric during stitching process is critical when evaluating fabrics with monofilaments. Main parameters considered are: 1 Importance of monofilament yarn.2 Evaluation criteria for monofilament yarn.3 Performance of monofilament yarn at fabric level & seat trim level.

Abstract Chrome plated plastic parts are extensively used across the automobile industry. Being exterior parts they are subjected to harsh environmental condition. Washing of vehicle will also make these parts more prone to corrosion. Thus the main aim while deciding chemical composition is to decelerate the process of corrosion. This paper describes the process of corrosion and general chemical composition of the overall layers to inhibit and delay the process of corrosion. An experimental study is done to establish the effect of variation in composition of plating layers.

Abstract The hybrid robot, will be a battery operated four wheel drive vehicle with a rigid chassis for all terrain operation. The vehicle will be suited for various payloads based on applications with geological, atmospheric sensors such as oxygen measurement, glacier thickness measurement, CO2 measurement, thermal properties measurement, salinity, buried object identification at a depth of 8 to 100 m., etc . The vehicle will be remotely controlled through a RF signal which allows it to maneuver up to 5 km. The novelty of the design, is its capability for all terrain and ease of trafficability based on skid steering, self alignment of sensors and vehicle traction in spite of possible inverted conditions and the vehicle can travel from land, snow, water and vice versa. The vehicle can be used in survey at coastline of water bodies, borderlines and can also be extensively used in polar region for studying glacier aging and as advance vehicle for the convoys and polar mapping.

Abstract The paper talks about machining techniques and solution approaches while machining Aluminium grade gearbox housings. Mahindra’s next generation gearbox housings are made totally of Aluminium; along with the higher strength to weight ratio that comes with using Aluminium come highly optimized ribbed structures that aid in achieving the said strength. While machining such Aluminium structures, it is imperative that the clamping forces do not load the component in ways it is not intended to. The paper talks about finish machining and proving out a semi-finished gearbox housing set (front, intermediate plate and rear) on a conventional Horizontal Machining Center (HMC). The input to the machine is the semi-finish housing that is already machined before with stock for finish operations.
