Summary

Description

The PMBS is used to conduct durability and performance tests on lunette trailers. It provides motion and force inputs to the test trailer's tires and lunette to reproduce dynamic conditions experienced at proving grounds. The PMBS fatigues the trailer the way a field test would, but under controlled laboratory conditions. Capabilities: The PMBS is designed to impart motion to an attached lunette trailer with the ability to conduct durability and performance tests on whole trailer systems. It moves the trailer lunette in three independent directions (vertical, longitudinal and lateral) while simultaneously providing vertical input to the trailer tires. The PMBS can accommodate trailers up to a gross vehicle weight of 20,000 lbs. and impart forces to the testing specimen via a bellcrank and strut arrangement. Benefits: •  Laboratory trailer testing offers the repeatability of dynamic events, and can eliminate performance variables such as weather conditions, driver variability and course maintenance. •  Extensive range of application design to integrate early stage development with flexibility to provide meaningful information that will minimize costs, accelerate development and compress test schedules. •  Provides a high-fidelity, multiaxial simulator that provides experimental test conditions for finite element analysis.
