Electromechanica, Inc. designed and constructed a custom Highly Accelerated Stress Screen (HASS) system as part of a quality assurance program for a major door systems company. This fully automated, LabVIEW® based test system applies a matrix of stressors to the device under test including:
- Thermal
- Line voltage
- Drive torque
- Release cable force
- Transmit and Receive RF levels
Environmental variables and all relevant device operating parameters are recorded during the test for predictive failure analysis.
Design elements for this project included:
- Design & fabrication of a custom RF shielding enclosure capable of withstanding the HASS environment
- Custom RF test system for Minimum Detectable Signal (MDS) determination and DUT control
- National Instruments LabVIEW® based test control and data acquisition program
- Fully instrumented mechanical load simulator for torque and linear force application
