US Air Force Landing Gear Test Facility (LGTF) – Aircraft Tire Dynamometer

Posted in Aerospace, Defense Contracting, Test and Measurement, Test and Measurement Automation

The Landing Gear Test Facility (LGTF) at Wright Patterson AFB's mission is to provide Research Development Test and Evaluation for aircraft safety and sustainment through world-class full scale test and evaluation of aircraft launch & alighting hardware (struts, wheels, brakes, tires, anti-skid, etc.). LGTF operates a large-scale, one-of-a-kind dynamometer for testing a range of commercial and military aircraft tires. The dynamometer evaluates tire performance and wear characteristics...

NASA Battery Simulation System

Posted in Aerospace, Automated Test Stand Design, Battery Pack and BMS Test Systems, Green Technology, LabVIEW Programming, Test and Measurement, Test and Measurement Automation

DMC leveraged our established Battery Management System (BMS) Testing Platform to deliver an automated Battery Simulator System to a NASA research group. NASA needed this system to facilitate development of highly specialized battery devices. These battery systems were designed to provide mobile power for advanced electromechanical systems such as Robonaut 2, a dexterous humanoid robot created to perform a wide range of tasks to assist astronauts on the International Space Station. The Battery Simulator...

High-Speed Motion Control for Aerospace with LabVIEW FPGA

Posted in Aerospace, LabVIEW Programming for Real-Time and FPGA, Manufacturing Automation and Intelligence, Motion Control Engineering and Servo Systems, Test and Measurement

DMC has worked closely with an Aerospace machine manufacturer to develop a high-speed control application for a highly coordinated process. Due to the nature of the process, an extremely complex and high-speed control strategy is required to ensure final product quality. The client recognized a proficiency gap in the processing technologies best suited to manage the controls application and reached out to DMC in order to supplement their development and design teams. DMC applied technology-specific...

Quality Assurance Test Lab for Aerospace

Posted in Aerospace, LabVIEW Programming, Test and Measurement, Test and Measurement Automation

DMC's client runs tension and torsion tests for a series of parts that it manufactures. The company requires 100% inspection, which had formerly been conducted manually with significant operator involvement. The test stands utilized for inspection use an MTS 407 servo-hydraulic controller, and the customer wanted a fully automated system where a LabVIEW PC application could send commands to and control the MTS 407 controller. Previously, an obsolete MTS function generator was used to send a control...

High Channel Count Thermistor Simulation

Posted in Aerospace, Automotive, Battery Pack and BMS Test Systems, Embedded Systems, Energy and Utilities, Green Technology, Test and Measurement, Test and Measurement Automation

As one component of a Client's complete test system solution, DMC was required to design and assemble a 50 channel temperature sensor simulator.  The resulting system is capable of simulating a collection of thermistor-based temperature sensors with 8-bit precision and 1% accuracy with 600V isolation between channels.

SAE J1939 Controller Area Network (CAN) Drivers for LabVIEW Applications

Posted in Aerospace, Automotive, Battery Pack and BMS Test Systems, Embedded Systems, Energy and Utilities, Green Technology, LabVIEW Programming, Manufacturing Automation and Intelligence, Test and Measurement, Test and Measurement Automation

DMC developed a set of J1939 protocol drivers for LabVIEW which are based on the NI-CAN channel API provided by National Instruments (NI).  DMC needed to interface to a customer's automotive ECU over CAN using the SAE J1939 protocol as part of an automated test application.  Since the application was written in LabVIEW and the test station used NI-CAN hardware, the drivers were entirely written in NI LabVIEW.  The drivers provide functions at a layer above...

3D Vision Inspection with LabVIEW

Posted in Aerospace, LabVIEW Programming, LabVIEW Vision Application Development, Manufacturing Automation and Intelligence, Test and Measurement, Test and Measurement Automation, Vision Inspection

DMC's client has a large aerospace component with chemically etched 3D geometry on the surface.  Due to the nature of the etching process and the tolerances required, the part must be inspected to ensure that all tolerances are met.  DMC created a 3D inspection that the customer has been able to integrate into their existing CNC based positioning system.  By using a 3D vision inspection for a part that contains thousands of inspection points the client is able to dramatically improve...
