Designing vehicles with good ergonomics is one of the many factors needed to achieve high customer satisfaction. A basic source for comfort (or discomfort) lies in the vehicle’s seats. To design for seat comfort requires knowledge of the size of the driver, the structure of the seat, the position of the seat in the vehicle and the trip duration. Papers offers in this session could include topics such as seat back angle, vehicle packaging and trip duration.

Heat transfer affects the performance, emissions and durability of the engine as well as the design, packaging, material choice and fatigue life of vehicle components. This course covers the broad range of heat transfer considerations that arise during the design and development of the engine and the vehicle with a primary focus on computational models and experimental validation covering the flow of heat from its origin in the engine cylinders and its transfer via multiple paths through engine components.

Context- In order to enhance fuel efficiency in buses an energy efficient air conditioning system should be deployed. This will lead to reduced parasitic load on the engine and translate into direct fuel saving. Fuel prices are increasing day by day; along with rapid depletion of fuel sources. Alternate fuels like CNG need investments in infrastructure, which is not available easily everywhere. Therefore fuel saving is vital. In case of air conditioned vehicles, the parasitic load mainly consists of power consumed by air conditioning compressor to pump the refrigerant and by blower motors and condenser fans for movement of conditioned air and heat removal respectively. Furthermore roof mounted bus air conditioning systems weigh in the range of 150-220kg (approx.) adding to the payload Necessity- Now days, most mid-size air conditioned buses are equipped with aftermarket solutions.

LCV AC buses market is rapidly growing up in India; major requirement is for staff pick-up and drop, school applications and private fleet owners. The air-conditioning system is typically mounted on bus roof top and located laterally and longitudinally at center. It is an easiest and most feasible way to package air conditioning system to cater the large passenger space (32 to 40seats) with the conditioned air. This makes air conditioning duct design simple and commercially viable. Most of the LCV buses are with front engine configuration which adds more heat and noise to Driver and passenger compartment, this demands for isolation of Driver’s area from passenger area by means of partition in between. Without partition engine noise is more dominant in passenger area, but in case of with partition, blower noise of roof mounted AC system is more perceivable in passenger area.

The main emphasis for a Commercial vehicle design which was focused on fuel-economy and durability does not fulfill the increasing customer expectations anymore. Commercial vehicle designers need to focus on other vehicle aspects such as steering, ride comfort, NVH, braking, ergonomics and aesthetics in order to provide car like perception to truck, bus drivers and passengers during long distance drives. Powertrain mounting system must perform many functions. First and foremost, the mounting system must maintain & control the overall motion of the powertrain, to restrict its envelope reasonably, thereby avoiding damage to any vehicle component from the potential impact. This requires the mount to be stiff. Second the mount must provide good vibration isolation to have a comfortable ride to the vehicle occupant. This requires the mount to be soft.

Gear noise and vibration in automobile transmissions is a phenomenon of great concern. Noise generated at the gearbox, due to gear meshing, also known as gear whine, gets transferred from the engine cabin to the passenger cabin via various transfer paths and is perceived as air borne noise to the passengers in the vehicle. This noise due to its tonal nature can be very uncomfortable to the passengers. Optimizing micro-geometry of a gear pair can help in improving the stress distribution on tooth flank and reducing the sound level of the tonal noise generated during the running of the gearbox when that gear pair is engaged. This technical paper contains the study of variation in noise level in passenger cabin and contact on tooth flank with change in micro-geometry parameters (involute slope and lead slope) of a particular gear pair. Further scope of study has been discussed at the end of the paper.

Certification of vehicle noise emissions for passenger vehicles, motorcycles and light trucks is achieved by measuring external sound levels according to procedures defined by international standards such as ISO362. The current procedure based on a pass-by test during wide-open throttle acceleration is believed to be far from actual urban traffic conditions. Hence a new standard pass-by noise certification is the new ISO 362:2007 is being evaluated for implementation that puts testing departments through their paces with requirements for additional testing under multiple ‘real world’ conditions. The new ISO standard, together with the fact that most governments are imposing lower noise emission levels, makes that most of the current models don’t meet the new levels which will be imposed in the future. Therefore automotive manufacturers are looking for new tools which are giving them a better insight in the Pass-by Noise contributors.

Pass – by testing is increasingly done In-door in a hemi-anechoic environment. Advantages of this method are high repeatability and independence of weather conditions. Often rooms smaller than the standardized size will provide accurate results. Product optimisation work often requires information about the noise contribution from the different vehicle noise sources. In this presentation different room sizes are discussed and an accurate time - based contribution analysis method is explained and documented with results from a practical example. Time domain has a number of advantages. The calculations are simple and hence the data are available for processing in other domains. It is possible to directly listen to the individual component contributions when working on exterior brand sound.

Use of Combined CAE and Experimental Testing Approach for Engine Noise Reduction Y. V. Surkutwar, A. A. Gaikwad, M.A. Patwardhan, N.V. Karanth, ARAI Pune Abstract The work presented in this paper deals with the use of combined CAE and experimental testing approach for reducing engine noise. The paper describes a systematic approach for giving solutions to structure borne engine noise related problems. Noise Source Identification (NSI) was carried out on diesel engine to identify noise radiating sources, ranking of noise sources was carried out and contribution of individual engine component in radiated Sound Level (SWL) was computed. Detailed Finite Element model of Engine assembly was developed and model was correlated in terms of natural frequencies and transfer functions by performing modal testing. Correlated FE model was used for predicting surface vibration velocities under various engine speeds and loading conditions in frequency domain.

An interior sound quality is one of the major performance attribute, as consumer envisage this as class and luxury of the vehicle. With increasing demand of quietness inside the cabin, car manufactures started focusing on noise refinement and source separation. This demand enforces hydraulic power steering pump to reduce noise like Moan and Whine, especially in silent gasoline engine. To meet these requirements, extensive testing and in-depth analysis of noise data is performed. Structured process is established to isolate noises and feasible solutions are provided considering following analysis. a) Overall airborne noise measurement at driver ear level (DEL) inside the cabin using vehicle interior microphone. b) Airborne and Pressure pulsation test by sweeping pump speed and pressure at test bench. c) Waterfall analysis of pump at hemi anechoic chamber for order tracking and noise determination.
