Mileage Accumulation / Performance

Overview

  • The Froude TeSys Endurance (mileage accumulation) systems utilise the same range of chassis dynamometers as for the emissions application.
  • 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.

Description

Main Features:
  • Automatic control for fully unattended testing
  • Powerful schedule generator
  • Meets US EPA and European cycle requirements
  • Low maintenance, high accuracy, and efficiency
  • Data acquisition and monitoring
  • Host file server and networking facility
Endurance Testing Systems provide full 24 hour unattended vehicle testing under automatic control. Vehicle and component ageing can be analysed within a controlled environment, or exposed to prevailing weather conditions.
Froude TeSys's Automatic Fuel Supply System is a common addition to this facility to support continuous testing and a safe working environment.
Quality Validation
  • Vehicles are taken from the production line at random or in a planned sequence for quality validation checks.
Specialist Testing
  • High performance Froude TeSys application software controls the dydnamometer so that it simulates a full spectrum of road load scenarios. This enables specific tests to be performed under laboratory conditions. Typical system configurations include 4x2, 4x4, and "independent" roller dynamometers.
  • The unique ability of Froude TeSys to engineer and integrate all of 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.
  • The core of the system is a comprehensive schedule generator function for creating, editing and executing the automated drive cycles. This utility in conjunction with the Robot Driver system provides a highly capable "real world" or regulatory simulation package with human driving capability and fully automatic operation of all the vehicle function.
  • Standard mileage accumulation cycles are pre-programmed and special and/or complex cycles are easily generated using the schedule generator or road gathered data functions.

Applications

  • Froude TeSys 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.
