Since the mid-1960s, tire-coupled road simulators (4-Posters) have been deployed worldwide for Buzz, Squeak & Rattle, NVH and Durability test applications. While traditionally servohydraulic, increasing demands for improved performance and greener, lower-cost operation have prompted MTS to pursue electrically actuated 4-poster systems. The introduction of an all-electric, durability-capable Model 320 marks the culmination of this pursuit, warranting a new look at the factors to weigh when comparing servohydraulic and electric 4-posters.
Join Richard Meyers, Senior Application Engineer, as he conducts a detailed exploration of 4-poster technology and its numerous applications, including an examination and comparison of conventional servohydraulic and recently introduced MTS iron-core linear electric solutions.

The new Model 320 ePost combines MTS iron-core linear electric actuation, FlexTest controls and RPC or First Road Interact software to provide a full range of passenger car and light truck testing, including Durability; Noise, Vibration and Harshness (NVH); Buzz, Squeak and Rattle (BSR); and Inline Production Quality.
