Resilient and Corrosion-Proof Rolling Element Bearings Made from Superelastic Ni-Ti Alloys for Mechanical Applications

Mechanical components (bearings, gears, mechanisms) typically utilize hardened construction materials to minimize wear and attain long life. In such components, loaded contact points (e.g., meshing gear teeth, bearing balls-raceway contacts) experience high contact stresses. The combination of high hardness and high elastic modulus often leads to damaging contact stress and denting, particularly during transient overload events such as shock impacts that occur during the launching of space vehicles or the landing of aircraft.

Particle Tracing Simulations with COMSOL Multiphysics

The Particle Tracing Module extends the functionality of the COMSOL Multiphysics environment for computing the trajectory of particles in fluids and electromagnetic fields, including particle-particle interactions. A variety of different forces are allowed to act on the particles including electric, magnetic and collisional for electromagnetic applications, and drag, gravity, dielectrophoretic, thermophoretic etc. for fluid applications.

Real-Time Fiber Optic Strain and Shape Sensing (FOSS) Technology

Researchers at NASA’s Dryden Flight Research Center have patented a lightweight, fiber optics interrogation algorithm that can be used for real-time wing shape sensing, temperature, and strain measurements. The virtually weightless fiber Bragg grating sensors, along with NASA’s efficient algorithms, provide strain data that enable precise calculations of shape, stress, stiffness (bending and torsion), temperature, pressure, strength, and operational loads in real time. Unlike conventional strain gauges which are heavy, bulky, and spaced at distant intervals, NASA’s fiber optic sensors are small, non-intrusive, easy to install, and provide high-resolution (0.5-inch) strain measurements that are much more precise than ever before. This critical, real-time monitoring capability detects changes during operation without affecting the intrinsic properties of the structure and without the need for structural modifications.

Eliminating Errors and Improving Accuracy in Motion Control and Machine Systems

Presenters will cover how to identify and eliminate contributors to and causes of positioning errors in motion control and machine systems. Mechanical, electronic, position feedback, and thermal issues will be addressed. The Webinar will also present strategies for elevating accuracy, including encoder influences on the motion control loop to get precise position and part accuracy, and how to design absolute position feedback systems using encoders and optimizing data interfaces.

Promote Interfacial Adhesion and Solve Delamination - An Engineer's Guide

Bonding high performance materials presents engineers with unique challenges to ensure immediate and long term interfacial adhesion success. Economic, environmental and productivity goals raise the stakes on the importance of finding the best solution when working with metals, polymers, adhesives, paints, coatings and other materials. In addition, more manufacturing materials are coming from the polymer composite world, which then must be adhered to metals and other substrates.

Designing Graphics for Safety Critical Systems Using OpenGL SC

Some implementations for graphics in embedded systems don’t fly in safety-critical uses. For an application to be DO-178B/C certified, all its components must be certifiable. Requirements such as determinism, SWaP, radiation hardening, and others make the situation even more challenging for designers, limiting possibilities.
