Characterization of the Automotive Interior Cabin Noise Research Proposal

Characterization of the Automotive Interior Cabin Noise - Research Proposal Example Consequently, interior trims such as the car-seats and roof covering play a very vital role in the observation of interior noise and vibrations specifically in relatively heightened frequencies (>400Hz). This therefore means that the automotive industry has had to focus on the redesigning the interior of this personal cars to make the cars as quiet as possible. The automotive industry has been compelled to enhance their interior trim products with better designs due to eco-friendly factors such as whether these products are recyclable, the fact that the noise and vibrating levels have the possibility of resulting to serious health issues and price of products. However, there is still a lot of research that need to be done in order to get a more profound understanding of the consequences of the interior trim design on the noise and vibrating levels. Once this improved and refined trim designs and concepts are recommended for the automotive industry, this need to enhance their interior trim products with better designs will become even more obligatory. Hence, this research paper is anticipated to deliver a practicable process which can estimate and optimize the interior cabin noise level for dissimilar interior trims and seating arrangement. In carrying out this research we first have to understand the effects of vehicle interior trims in minimizing interior cabin noise. In doing so, we will begin by establishing the noise characteristics. In establishing the noise characteristics of interior design, I will peg my research on a paper published by Jha and Priede which investigated the simplest mechanism of understanding how noise is generated in a car. This noise is majorly caused by the vibration of the cabin walls. While this research was carried out over 30 years ago the findings from this research are still applicable with the design and features of an ordinary modern day vehicle. Jha and Priede carried out experiments of internal noise spectra of a number of vehicles. The internal noise spectra of the vehicles were also done at contrasting speeds. The internal noise spectra was seen to elevate to an all-out level of 20 Hz and later decrease at a constant rate of averagely 25 Db per decade to a level exceeding 1 kHz. Although, the frequency at which the highest level of noise is experienced normally depends on the size of the car, the corresponding interior noise spectra for all personal vehicles as investigated by Jha and Priede are all alike. The rotation of the wheels are one of the major contributors of interior noise and vibrations whereby they result to noise peaks of about 20 Hz which in combination with various harmonics result to a lot of noise and vibrations within the car. The engine is also a major contributor of these noise and vibrations within the car whereby when an engine fires it produces harmonics of a low order that account for a frequency of about 100Hz. The second part of this research will be identifying the role of different trims in absorbing noise and vibrations produced within the cabin. The most commonly used trims are Acoustic Insulation materials. These materials that are applied in the reduction of noise and vibration levels within a personal car have the following mechanism; they first absorb the energy produced which is then transformed into heat energy. This transformed sound energy is reflected away from the vehicle. The acoustic insulation

Effectiveness of Strategy at Subsidiary Level Essay

Effectiveness of Strategy at Subsidiary Level - Essay Example It is the method of aligning all the activities being undertaken in the organisation such as management, marketing, research and development and Computer information system in a prescribed way to achieve the goals of the organisation. The first step namely the strategy formulation involves the development of the business mission, evaluation of the opportunities and threats faced by the business organisation in the business, by using tools such as SWOT analysis, examining the strengths and weaknesses of the business, determining the long term objectives of the business and designing the new strategies to eke in the process of achieving the new targets. It also include the processes to determine the investment direction, the business markets to be addressed, extension of the operations of the business, limitations faced by the business in order to undertake the business activities. Strategy formulation also helps the business in deciding about the matters to be addressed on priority basis. There is not any organisation in the world which has unlimited resources. Therefore the business organisations need to evaluate which projects are important and need investment. The future of a business organisation is very much effected by the strategic decision of the management of the organisation. With the globalisation of the economy the concept of Multinational Enterprises is prevailing all over the world. An MNE is a differentiated network of internationally dispersed units, which are simultaneously embedded in two business contexts: the internal MNE and the external (host country) environment. Thus, the roles and/or strategies of subsidiaries are both shaped by and affecting these two contexts. A subsidiary has a dual role to play: it interacts with the rest of the MNE internally and with local partners externally. Firstly, while subsidiaries can benefit from knowledge flows from the rest of the MNE, they can also do so from the local partners in the host country, to enhance their level of competence and hence contribute to the overall competitive advantage of the MNE. Secondly, subsidiaries may also help or hurt their local partners during their external interactions in the host country business environment. It has been argued that the state of the economy of the host country has significant implications for the operation of the subsidiaries, and consequently for its strategy (Hunt and Morgan, 1995). Because of this the main macroeconomic concepts relating to the determination of economic activity, and related issues such as the inflation rate and the exchange rate, have been discussed in some detail. The various factors affecting the company should
