The Engineering Test Tools Division offers custom applications development (LabVIEW Software Development, and LabVIEW systems integration).   We have  LabVIEW developers (certified LabVIEW developers on staff), Engineers, and a diverse support staff available to produce custom advanced software/hardware applications.  In addition to LabVIEW programming we provide development services for embedded and PC based applications using several other low level programming languages or analysis tools such as, Test Stand, DIAdem, Matlab, Simulink, Mototron, LabWindows/CVI, C, C++ ,.net, and Visual Basic depending on the requirements of the application.   Some of the applications (software and/or hardware) are listed below.  To contact Roush regarding Custom Application Development, or full system integration please contact ettsales@roush.com, or call 734-779-7877.

End of Line - Seat Tester
This system performs a seat track functionality check on every end of line production part at a customers’ facility. Utilizing National Instruments PXI hardware, LabVIEW programming language and industry standard communication protocol (J1850), this system controls seat track movement, and tests communication, lumbar adjustment, heater control, recliner adjustment, and all wiring. Each seat track is assigned a barcode via a printer, and each test result is logged into a central database.

 

Automotive Hybrid Vehicle Component Testing - Electric Motor Dynamometer
The Electric Motor Dynamometer is used for the testing of electric motors. The Dyno bench is meant to run stand-alone and includes a coolant circuit with an on-board heat exchanger and an optional oil lubrication circuit for motors that require lubrication. The regenerative drive allows for bidirectional rotation and torque. The on-board embedded controller continuously monitors dozens of safety limits and can safely shutdown the entire system to protect personnel and equipment.



Engine Development -  Engine Dynamometer
The Engine Dynamometer is used for the testing of alternative fuel engines that require an extremely robust safety/limits system to prevent damage during testing. The Engine Dynamometer was developed using LabVIEW software and cDAQ hardware.  The Engine Dynamometer software application has the ability to sample and log data as well as control engine speed and torque (via an external controller).  The software has a user configurable safety/limit system as well as an integrated watchdog timer to validate program integrity.





Manufacturing - Alternator Housing Tester
The Automated Alternator Housing Inspection system inspects for alternator surface defects utilizing National Instruments LabVIEW software, PCI hardware and IMAQ vision equipment. An internal housing structure vibration analysis is carried out using Dynamic Resonance Systems (DRS) hardware utilizing ultrasonic spectroscopy. Each part is inspected in less than five (5) seconds and results are logged into as MS Access database. Images are saved from all part angles for later analysis and results can be viewed via LAN, WAN and the Internet.




Automotive - Turbo Control System
This system provides control of an aftermarket variable geometry turbine (VGT) turbo charger for use on a 150,000 mile on-road durability test. The National Instruments Compact Fieldpoint based system intercepts CAN messages on the vehicle’s CAN bus for use as turbocharger control inputs (engine speed, backpressure, oil temperature and torque). The system enables high speed real time control of the turbocharger. The system is equipped on two separate light duty Diesel test trucks undergoing 150,000 mile durability in extreme environments, one with a heavy towing load.




Automotive - DTV Test System
This LabVIEW based test station performs on-vehicle disc thickness variation (DTV) measurements and simultaneously report residual brake drag by measuring variations in brake torque. DTV measurements are calculated by measuring inner and outer run outs at three prescribed locations on the face of the rotor using six proximity probes and similarly the brake torque is measured by using an on line torque transducer. The purpose of performing a Disk Thickness Variation (DTV) measurement is to quantify the accumulation of contamination (friction material, road grime, dust, salt etc) on the brake rotor (disk). Contamination buildup on brake rotors that increase the thickness variation can contribute to vehicle roughness during high speed off-brake conditions.
