Description: Bei der Konstruktion neuer Produkte bestehen viele Anforderungen, deren Einhaltung der Konstrukteur sicherzustellen hat. Wesentlich sind dabei neben der Erfüllung der Gesamtfunktion auch die Kostendeckung und die Zuverlässigkeit des Systems. Maschinenakustische Anforderungen gewinnen durch verschärfte gesetzliche Bestimmungen und durch steigenden Wettbewerbsdruck an Bedeutung. Im Rahmen des Projektes wurde ein computergestütztes Beratungssystem für den Konstrukteur entwickelt, dessen Aufgabe es ist, auch in frühen Phasen der Konstruktion maschinenakustisches Wissen bereitzustellen. Damit soll der Konstrukteur in die Lage versetzt werden, bei allen Konstruktionsentscheidungen auch akustische Belange zu berücksichtigen, so das aufwendige und zeitraubende Nachbesserungen an der fertigen Maschine vermieden werden können.

Title: Work Methodology for Development of Quiet Products (EQUIP)
Description: General Information: To achieve the low noise levels imposed by the evolving European and national regulations, current practice in traditional industries consists of searching for ad hoc solutions at the prototype stage of product development. This trouble-shooting and search for solutions is mainly achieved by specialists in acoutics. Quiet products often are associated with high quality, increasing consumer confidences and thereby market potential. The main objective of this project is to provide the designer with a 'consulting system' based on the designer's perspective of his work methodology, to obtain low noise products from well conducted design. The project consist of four principal research tasks: 1. Product specific acoustics: Analysis and application of the acoustic design methodology during the real design process of earthmoving machines, municipal vehicles, refrigeration equipment, heating and airconditioning systems. 2. (Low noise) Design methodology: Development of a broadly applicable methodology for designing quiet products. 3. Software and knowledgebases: Development of a consulting system based on low noise design methodology. 4. Measurement methods: Development of missing measurement methods needed to acquire essential data for the low noise design process. Successful completion of the project should enable the industries involved to develop quieter products, increasing market share by about 10 percent and reducing time-to-market by 10 percent. Potential noise reductions of between 3-10 dB (A) are envisaged, effecting both noise at the workplace and community noise. Achievements: A methodology and a knowledge-based system for low noise design have been developed that provide the designer with new tools to assist in designing low noise machinery and equipment. The methodology was based on an analysis of the design process, identifying the main activities and the flow of information relevant for noise control, and an inquiry in industry providing requirements from design engineers. An approach for component-based noise path modelling has been developed, enabling the designer to describe and model a machine or a structure in terms of acoustics. A limited set of components and noise generation mechanisms has been defined, which covers most machinery noise situations. The computer tool consists of a noise path modeller with help facilities, datbase browsers, calculation facilities and a macro facility. Depending on the design phase, eihter a qualitative or a quantitative approach can be taken. The designer can set requirements, identify low noise design principles and components, perform noise level calculations and spectral ranking, and assess combinations of noise measures. In parallel to the methodology development noise control work was carried out on 3 different types of machine: excavators, municipal vehicles and water chillers. Noise reductions of 5-11 dB(A) were achieved by ....
