Mileage Accumulation & Performance

TeSys Endurance (Mileage accumulation and Performance)

chassis systems utilize the same range of chassis dynamometers as for the emissions application.  

By integrating a robot driver, automatic re-fueling device, 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.

• High performance TeSys application software controls the dynamometer 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 TeSys to engineer and integrate all of the devices into one complete test automation system realizes many features and benefits for the test engineer including: reduced interfaces and controllers, fully integrated control and data acquisition, synchronization of test cell subsystems (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.

TeSys supplies a wide range of vehicle test benches which are specifically designed for testing motorcycles, passenger cars, light to heavy-duty trucks, buses, agricultural vehicles, military vehicles and specific component sub-assemblies.

Applications are as varied as follows:

• Climatic test simulating extreme hot and cold operating conditions
• Low noise and vibration
• Gale force winds
• Prolonged high speed operation (> 300 km/hr)
• Condensed vehicle life tests(> 100,000 miles)

Various AC motor and roll configurations are available, either in-line, or center-mounted (MIM:Motor-in-middle) and independent. Inertia simulation ranges cover motorcycles to heavy-duty commercial up to military vehicles.
