Change visitor typeROTOTEST VPA-RX Chassis Dynamometer - Engineering aspects
Although the basic principle of operation of the ROTOTEST® VPA-RX™ dynamometer is simple, its control and measurement system is far from simple. The highly advanced control and measurement system is the result of more than 20 years of development of hydraulic chassis dynamometers. The ROTOTEST® VPA-RX™ incorporates distributed intelligence technology with parallel multi-processor architecture and an autonomonous operation of each individual dynamometer unit. This combined with the adoption of the latest control algorithms, provides a solution which is incomparable, it simply must be experienced.

  • Slip-free - Patented designed dynamometer with direct coupling to the wheel hubs (drive shafts).
  • Outstanding performance - The ROTOTEST® VPA-RX™ series of dynamometers offers a wide range of performance (power, speed and torque).
  • Patented torque system - Patented torque measurement system with exceptional torque accuracy.
  • Synchronous measurement - A dynamometer with high-speed synchronous measurement of torque and speed resulting in state of the art dynamometer control and measurement accuracy.
  • Calibrateable - Any professional grade dynamometer needs to be calibrateable. The ROTOTEST® VPA-RX™ dynamometer is torque calibrated using dead weights.
  • Zero inertia - The detection of minimal load changes is ensured by Rototest's dynamometers, which by design have a negligible inertia.
  • Portable & Space saving - Easily movable wheel hub units (less than 200 kg per wheels) between rear- and front wheel drive (Saves space compared to a roller installation). And also between different test sites.
  • User friendly - A user-friendly dynamometer with an intuitive designed software interface.
  • Multi purpose - A multi purpose dynamometer system with a wide range of accessories; designed for different test purposes (Data acquisition system, NVH-, low temperature- and differential testing etc).
  • No tyre noise - With the tires removed, there will be no tyre noise.
  • Normal suspension handling - The professional car set up (installation) of the ROTOTEST® VPA-RX™ dynamometer system enables a natural movement of the suspension during testing with only negligible influence.
  • Centre nut - A wheel hub connection system that will allow installation to any type of wheel hub.
