Model 320 Tire-coupled Road Simulators

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.

Applications

  • Durability
  • Noise and Vibration Transmissibility
  • NVH
  • BSR
  • Ride / Comfort Assessment
  • Road Holding
  • Production End-of-Line - Quality Control

Test Specimens

  • Passenger Cars and SUVs
  • Light Trucks
  • Heavy Trucks
  • Motorcycles
  • All-Terrain Vehicles
  • Off-highway Vehicles
  • Motorsport Vehicles

Key Product Features

Durable / Reliable

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.

Accurate / Repeatable Results

High-performance MTS servohydraulic or electric actuation delivers precise, high fidelity road load reproductions.

Efficient Operation

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.

Versatile

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.
