Model 329 Spindle-Coupled Road Simulators

Apply force and motion in six degrees of freedom through vehicle spindles to replicate the effects of real-world road loads on vehicle and subsystem durability. The latest iteration of this industry standard test system, the new Model 329i, combines a refined kinematic design, versatile FlexTest controls and renowned RPC software to achieve new levels of test productivity and accuracy.


  • Durability

Test Specimens

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

Key Product Features

Accurate / Repeatable Results

Refined kinematic design supports higher dynamic inputs (up to 80 Hz) and delivers superior closed loop control with minimal latency (0.35 ms)

Integrated / Synchronized

FlexTest digital controls enable reliable and seamless connectivity between the test rig and the specimen, including specimens with active systems

Accelerated Testing

Combining the test rig with market-leading RPC software allows engineers to replicate real damage from road events up to 10x faster than on the proving ground

Unmatched Expertise

Global experts on road simulation support users to design tests and methods, including implementation of MTS’ ground-breaking HSRC technology that reduces reliance on traditional RLDA
