Full Vehicle Testing

Overview

Testing for automotive, truck, and agricultural testing needs. Can quantify long term effects of extended operation under cold soak conditions, freeze/thaw testing, deep freeze cold storage. Also can provide testing for vehicle corrosion, emissions, solar load, and integration with chassis dynamometer test equipment. Single vehicle to multi-Class 8 configuration.

Features

  • Multiple performance packages are available depending on low end temperature requirements, transition rates, live load values, humidity requirements and total mass of test article

  • Water or air cooled condenser refrigeration systems available

  • Direct expansion refrigeration system standard, options available for secondary “brine” conditioning for added control capabilities

  • Chamber can be integrated with external testing equipment systems including servo actuated and electro-dynamic shakers

  • Optional wall mounted sound attenuation panels available, for semi-anechoic sound testing

  • Available in Class 1 Div 1 construction

Solar array for testing in a drive-in vehicle chamber.

Infrared Solar Array

Ideal for simulating a directed radiant “heat load” environment.  Reproduce and simulate daily cycle of solar conditioning and heat intensity from sunrise to sunset. Ideal for climate control testing.  Perform “body” or “exterior” test studies at varying loads and qualify effects of long term heat exposure under varying conditions.

Features

  • Multiple zones of control. Vary solar heat load intensity based upon a specific location or UUT profile.

  • Optional “side” and “frontal” profile adjustment enables pinpoint directional placement of heat load on body test structure.

  • Manual or automated vertical adjustment of solar bank enables an unlimited selection of height placement per vehicle standing profile.  Fixed placement arrays are also available.

  • “Portable” or “Moveable” systems available. Caster mounted fixtures designed for ease of transport into and out of test environment.

  • Customized bulb placement, spatial orientation and zones of control available per customer requirement.

Emissions and Cold Start/Soak Testing

Full vehicle emissions testing programs, including Federal Testing Procedures (FTP), Supplemental Federal Testing Procedures (SFTP), light to medium duty truck testing. 48” or 72” integrated chassis dynamometer, with velocity road speed fan simulation. Fixed or movable wheel base, front, rear or four (4) wheel drive and Up to 450 Hp per Roll. Optional connecting soak room maximizes run time and test schedule. Full solar spectrum simulation with programmable zone. Fuel Tank Temperature management (FTTM) and “Hot Road” simulation available.

Can quantify long term effects of extended operation under cold soak conditions. Performs vehicle “defrost” and “climate control” testing.
