Quartus Engineering

Still planning your agenda at Spacecraft and Launch Vehicle Dynamic Workshop 2024 next week? Be sure to be in the room on Wednesday, June 5th when Joshua Gorfain from Quartus Engineering talks about Insights into the Shock Response of the NASA ShockSat from Explicit Dynamics FEA. Shock is a persistent technical challenge for spacecraft and launch vehicle systems. The modeling and simulation of shock events has been an active area of interest for many years. Shock testing has its own challenges, primarily related to good experiment design, acquisition of quality data, and proper physical interpretation. Explicit dynamics finite element analysis (FEA) has been previously shown to successfully predict and interpret the shock response of various systems. Here, this technique is applied to NASA’s ShockSat as a case study of a spacecraft-like system. Shock tests from the original ShockSat experimental program are directly simulated and compared to the measured data. Analysis of both data sets present useful insights into the shock propagation through such a system, emphasizing placed on the underlying physics. Merits and limits of the simulations are discussed, as is their relation to current, industry-standard practices.  

Are you going to be at Spacecraft and Launch Vehicle Dynamic Workshop 2024 next week? Be sure to be in the room on Wednesday, June 5th when Adam Johnson from Quartus Engineering talks about Improved Vibration Test Predictions Leveraging a Pre-vibe Modal Screening. Finite Element Models (FEM) play a critical role in planning small satellite vibration tests and making flight predictions. Not only are they critical in predicting key margins and failure modes, but they also help understand and control load that enters the structure. In lieu of interface force measurement hardware, accelerometer response limiting is common in both random and sine vibration testing. This method offers a cost-effective approach however, it relies on a correlated FEM. In this presentation, Quartus explores the feasibility of leveraging a pre-vibe modal screening to improve predictions ahead of a vibration test under practical constraints of a small satellite program. The proposed procedure utilizes a pre-vibe modal screening along with previously established techniques for handling common boundary condition challenges for fixed-base testing.

From all of us at Quartus Engineering, we wish you a happy and safe Memorial Day. Before you celebrate your day, please take a moment to remember them.

Look what just showed up at Quartus!   We are excited with our new TVAC chamber. Quartus is investing in our client’s needs by bringing TVAC testing in house focused on optical systems development support and analysis capabilities.   The TVAC chamber will be equipped with optical window to enable active thermal-vacuum testing over temperature.   Do you need help testing and characterizing your optical systems for harsh environments? Reach out to find out what you can have access to on your programs!   Where you can find this capability: National Labs Government Primes AND NOW… Quartus Engineering!   Enclosure dimensions: 48” diameter x 60” long #EngineeringForward #Testing #TVAC #Optics #Space

The doors are open for the last day of Automate Show! Don’t miss two opportunities to talk to our team! At booth #5018, learn about #PixelTraq, our traceable camera calibration. In Edmund Optics booth #1413, talk with our engineers about our binocular depth mapping capabilities. #EngineeringForward

The Automate Show doors are open! Stop by Booth #5018 to chat with our team about our patent-pending products! #OptiQuiver and #PixelTraq

Are you planning to be at the Automate Show in Chicago, IL? Stop by Booth #5018 to chat with our engineers about our new technologies available for your next project!   PixelTraq is a patent-pending camera calibration architecture that produces accurate, robust and fully traceable calibrations for single cameras and multi-sensor instruments. PixelTraq is configurable for a wide variety of camera parameters including field-of-view, working distance, wavelength, target density, chart design, electronic interface and camera model. Quartus Engineering offers PixelTraq as a calibration service, as the foundation of custom machine vision solution, or as a turn-key calibration station. Quartus will have a PixelTraq Calibration Station at the Automate Show for live demonstration.   OptiQuiver is a patent-pending optical instrument that combines precise wavefront sensing and tilt measurement across a large dynamic range. OptiQuiver contains an internal reference light source for measuring figure of reflective surfaces and double-pass transmitted wavefront, but can also accept external light sources for flexible integration with customer applications. Quartus will have OptiQuiver and an automated optical alignment live demonstration at the Automate Show.
