Apply vertical forces through vehicle tires to replicate the effects of real-world road loads on a wide range of vehicles. The original laboratory-based road simulator, today’s Model 320 combines linear electric or servohydrualic actuation, FlexTest controls and RPC or First Road Interact software to support applications ranging from end-of-line production quality to vibration transmissibility to durability.
Test Standards C
Model 320 systems can perform in high duty cycle and high capacity testing for decades without a breakdown, requiring only limited routine maintenance and service.
High-performance MTS servohydraulic or electric actuation delivers precise, high fidelity road load reproductions.
Versatile 793 controller software, renowned RPC software and easy-to-use First Road Interact software enhance the operational efficiency of both novice and expert lab personnel.
The Model 320 product line can test all types of ground vehicles, including motorcycles, scooters and ATVs; passenger cars, light and heavy trucks; as well as train cars and off highway vehicles.
