The Model 4950 Two-Roll Chassis Dynamometer provides an excellent platform for single axle vehicle and vehicle corner NVH testing. The corner fixtures provide the capability to test one or two full-suspension corners with full instrumentation for performance monitoring, along with NVH data.
Typical applications include brake, tire, powertrain, and suspension tests. A wide range of rolls sizes and surfaces can be specified to meet particular test requirements. All test operations are controlled by the ProLink software package that runs under Microsoft Windows®, and integrates dynamometer control, data acquisition, data analysis, and reporting in one easy to use package. ProLink provides inertia simulation capabilities so that no inertia discs are required.
For NVH measurements the Brüel and Kjær PULSE system provides excellent data acquisition and analysis capabilities that are controlled by the ProLink software. The end result is a powerful combination of test, data acquisition, and analysis capabilities that can be incorporated in a test program without the need for an NVH expert. ProLink also provides the ability to easily access all performance and NVH data from other Microsoft Windows compliant packages such as Excel and Matlab.
