During the month of April, Crystal Instruments was proud to host two installments of our new webinar series. The first installment took place March 31st to April 2nd and focused on vibration basics, as well as vibration control testing for random vibration profiles. The second installment, which took place April 14th to April 16th, focused on modal analysis concepts and carrying out a modal test using Crystal Instruments Experimental Modal Analysis software.
Read MoreWhen designing and testing materials and products it is essential to understand its material properties and how it reacts to the forces and loads applied to it. The deformation a DUT experiences when a force is applied is called strain. Strain is the ratio of the change in length of a material to the original length. Strain can be positive (tensile) or negative (compressive).
Read MoreMultiple input multiple output (MIMO) testing has many advantages when compared to data collected from single input single output (SISO) testing. The energy from multiple shakers allows the structure to be more uniformly excited throughout the entire structure and thus allows for the development of better frequency response functions (FRF).
Read MoreThe International Safe Transit Association (ISTA) partnered with Amazon.com to develop the 6-Amazon.com testing series to challenge the capability of packages and products to withstand transportation standards while utilizing the general simulation of actual transport hazards. Please note that these tests may not comply with carrier packaging regulations and are designed only to address transportation hazards.
Read MoreDuring the first week of March, Crystal Instruments hosted an International Sales Meeting for our European distributors in Barcelona, Spain. Guests representing our distributors in Europe attended the meeting: Scanditest, Alphatech Ltd, dB Vib, Kistler Eastern, Kvalitest, Alava Ingenieros, Akron, Balkanlar, ADM, Viaxys, Disynet, Sensing, VibroAkustik, Ecspdm and emTEST.
Read MoreI expected that eventually you would get around to asking me that question. Its another one that I get asked all the time. Basically the simplest answer is that you need to measure a sufficient number of points so that you can uniquely describe the mode shape. This answer may not be completely obvious. We need to talk about this a little more. Let's start with a simple structure that we have discussed before. The simple plate structure.
Read MoreThe 5th annual SmallSat Symposium returned to the Silicon Valley Computer History Museum for 2020, where leaders gathered to discuss the latest technologies and market dynamics. Crystal Instruments and Sentek Dynamics had the privilege of exhibiting products and solutions for the small satellites industry.
Read MoreMultiple-Input Multiple Output (MIMO) Testing has gained a huge momentum in the past decade with the development of multiple shaker table systems, the availability of MIMO vibration control systems, and the readiness of standards (e.g., MIL-STD 810G Method 527, IEST DTE 022 Working Group Recommendation).
Read MoreCrystal Instruments attended the IMAC XXXVIII conference and exposition in Houston, Texas last week. The IMAC conference focuses strongly on structural dynamics and has evolved to encompass the latest technologies supporting this field. Every year, IMAC welcomes many first-time attendees from post graduate schools all over the world.
Read MoreA socket client can send messages to EDM and may receive data or an acknowledgment message as a reply. Users can configure the event-action rules of a vibration control system (VCS) test to send socket messages to a socket client when certain system events occur.
Read MoreIntroducing EDM Time Data Acquisition (TDA), an intuitive easy-to-use software interface for acquiring, viewing, and recording raw time data received from the input channels of any of Spider front-end system.
Read MoreVibration testing of automotive components helps manufacturers ensure both a sound design and improved reliability. The current growing demand for electric vehicles has placed battery testing into the spotlight and as a result, attention for vibration tests of electric vehicle batteries has increased.
Read MoreCrystal Instruments and Sentek Dynamics attended the 90th Shock and Vibration Symposium in Atlanta, GA. Topics covered at the symposium included shock-ship testing, water shock, weapons effects (air blast, ground shock, cratering, penetration) shock physics, earthquake engineering, structural dynamics, and shock and vibration instrumentation and experiment techniques.
Read MoreThe latest 8.1 release of the Crystal Instrument’s EDM Modal software features multi-Resolution spectrum technology implemented into the MIMO FRF testing suite. Multiple passes of FFT yield a much finer resolution in the lower frequency region. This provides the advantage of a better estimation of the quality factor (or damping) and the amplitude of the frequency response functions at the resonant frequencies.
Read MoreCrystal Instruments is pleased to announce the release of EDM 8.1, the most advanced featured version of Engineering Data Management software. With this new release, advanced new products have been added to the Crystal Instruments’ family of products along with exciting new features across all EDM modules. Improvements to existing features and bug fixes make this release more user-friendly and robust.
