The Model 4900 provides the capability to evaluate a wide range of vehicles and a full set of tools for control and measurement. Typical applications include powertrain, brake, tire, and interior trim evaluations. Teamed with the Brüel & Kjær LAN-XI analyzer the Model 4900 provides a state-of-the-art system for facilitating vehicle measurements and analysis. With an automated system for wheelbase adjustment, the Model 4900 can accommodate vehicles from the smallest passenger car to the largest light truck. Typical configurations range from wheelbases of 2.16 to 4.45 m (85 to 175 inches). The result is a very versatile test apparatus with many applications. A key criterion in the Model 4900 is keeping the background noise levels as low as possible to assure high quality noise and vibration measurements. To this end, the rolls are completely enclosed except for the running surface in the room above. The drive motors and other related power equipment are isolated in a separate room or placed in high transmission loss noise enclosures. The result is a background level that is low enough to permit the most sensitive noise measurements. Included with the Model 4900 is a complete control and measurement system. The core of this system is the ProLink™ software package that integrates all control, measurement, analysis, and reporting functions. ProLink has been cited as one of the most versatile and easy to use test software packages in the industry. By integrating all the major control and data acquisition functions, ProLink makes automated test programs easy to program and deploy.
