DESIGN AND CONSTRUCTION CONSIDERATIONS FOR AUTOMOTIVE AND AUTOMOTIVE COMPONENT ACOUSTIC TEST FACILITIES

摘要

The topic of this paper is the complete system design consideration necessary to meet the testingrnrequirements for automotive NVH applications including engineering data for Anechoic and Hemi-rnAnechoic Chambers.rnDifferent design criteria must be established so that the facility design takes into account all elements ofrnthe client's testing needs. A detailed checklist is compiled that contains all issues that must be addressedrnto ensure the highest levels of performance and accuracy.rnEngineering and design considerations will focus on the following areas: attenuating structuresrn(enclosures), anechoic wedges, doors, windows, working floors, vibration isolation systems, ventilation,rnsilencers, lighting and electrical systems, instrumentation hangers and penetration sleeves.
