Product catalog summary
Overview
The document provides detailed information about the 4-Roll NVH Chassis Dynamometer Model 4900 by Link Engineering Company. It highlights the specifications, applications, and customization options available for this testing equipment.

Specifications
The Model 4900 features an isolated sub-frame foundation, a 6-channel noise acquisition system, and supports a maximum axle load of 5443 kg (12,000 lbs) and a minimum axle load of 907 kg (2,000 lbs). The roadwheel diameter is 1829 mm (72 inches) with a width of 711 mm (28 inches), and it can achieve a maximum road speed of 225 kph (140 mph). The drive motor size is 224 kW (300 HP) per axle, and it accommodates vehicle wheelbases from 2.16 to 4.45 meters (85 to 175 inches).

Applications
The dynamometer is designed for diagnosing and resolving vehicle noise, vibration, and harshness (NVH) issues. It is suitable for evaluating powertrain, brake, tire, and interior trim. The system is equipped with the Brüel & Kjær LAN-XI analyzer for advanced vehicle measurements and analysis.

Features
The Model 4900 includes an automated system for wheelbase adjustment, allowing it to test a wide range of vehicles from small passenger cars to large light trucks. It ensures low background noise levels by enclosing the rolls and isolating drive motors in separate rooms or noise enclosures.

Control and Measurement System
The ProLink™ software package integrates control, measurement, analysis, and reporting functions, making automated test programs easy to program and deploy. It supports over 200 data acquisition channels and facilitates data analysis using Excel macros, Matlab, and other Windows tools.

Customization Options
The Model 4900 can be customized with options such as a hemi-anechoic chamber, environmental conditioning system, individual drive motors for each road wheel, road surface castings on rolls, pop-up engine cooler, and vehicle tie-down and safety systems.

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.
