Mileage Accumulation & Performance

Endurance Testing

Our Endurance & Performance (Mileage Accumulation) systems utilise the same range of chassis dynamometers as for the emissions application. This provides not only the reliability expected from a machine that will operate 24/7 but also the accuracy to provide meaningful results.

As Standard a range of machine configurations and powers are available from 150kW 2WD for Light Duty passenger vehicle applications to high power fully independent 8 or 16WD units for high capacity commercial or special application vehicles.

By integrating a Robot Driver, automatic re-fuelling, air speed simulation fans, data acquisition and safety devices, we provide a fully automated test cell, enabling unsupervised, 24-hour testing of the vehicle over its expected lifespan, (typically 100,000 miles or more) in an accelerated time period.

Main Features

  • Automatic control for fully unattended testing
  • Meets US EPA and European cycle requirements
  • Low maintenance, high accuracy, and efficiency
  • Data acquisition and monitoring

We have been involved in the supply of Mileage Accumulation Chassis Dynamometer test systems from the earliest requirements for the regulatory U.S.E.P.A. 50, 000 miles, exhaust system endurance testing. With the development of our product capability and the increasing demands for more sophisticated test requirements from our customers, this application has evolved into a fully flexible Automated Test solution. These systems now include a Chassis Dynamometer, an integrated Robot Driver, automated fuel filling units, comprehensive Data Acquisition, airspeed simulation fans, automated safety guards and security systems for unattended operation 24hrs a day / 7 days a week – collectively providing a highly effective, advanced endurance or rapid development test facility.

As the capability of the systems has increased, the Test Engineers have been able to produce more intricate simulations of real world situations under controlled conditions. What used to be called a “Mileage Accumulation Facility” now also provides a variety of dedicated and sophisticated tests for powertrain development.

Our unique ability to engineer and integrate all the devices into one complete test automation system realises many features and benefits for the test engineer, including; reduced interfaces and controllers, fully integrated control and data acquisition, synchronisation of test cell sub systems (robot driver, automated fuel filling systems, airspeed simulation fan), automated drive cycle control and monitoring and effective integration of all the safety systems.

Specification

We supply a range of Vehicle Test System products to the automotive and commercial vehicle markets which are specifically designed for testing passenger cars, light to heavy-duty trucks, motor cycles, buses, agricultural vehicles, and specific component subassemblies.

Applications are as varied as follows:

  • Climatic test, simulating extreme hot and cold operating conditions
  • Low noise (<45dBA)
  • Gale force winds
  • Prolonged high speed operation (>250 km/hour)
  • Condensed vehicle life tests (>100,000 miles)


Various AC motor and roll configurations are available, either in-line, or centre mounted (M.I.M.). Inertia simulation ranges cover motorcycles to heavy-duty commercial vehicles.
