Project Description

 

Door Operator HASS

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
