AB Dynamics launches improved NVH analysis test tool

0

AB Dynamics has updated its Plato NVH test system, which is used to test a range of products including automotive transmissions; axles; 4×4 transfer cases; power take-off units; cold, crank and hot engines; and power steering systems, as well as complete vehicles and component parts.

This latest version, Plato 7.25, now contains enhanced dynamic backlash measurement capabilities with additional methods for backlash calculation, such as reversal of rotational direction and load direction (torque ‘flip). Backlash can be calculated by measuring pulse durations from high pulse rate encoders, and with this latest version, backlash can also be measured using encoder edge-counting.

Plato supports numerous National Instruments data acquisition hardware options and the latest software now supports the PCIe-6612 plug-in card with up to eight high pulse-rate encoder channels being measured simultaneously in pulse duration or edge-counting modes for analysis of complex drivelines and gear systems.

Plato also includes functionality for test machine health monitoring in parallel with product testing and the latest software provides additional information when trend data is reviewed.
