Multiple-Input Multiple-Output (MIMO) vibration testing has increased in popularity as a result of the development of multiple shaker table systems and the availability of MIMO vibration controllers. The readiness of standards such as Mil-STD 810G Method 527 and the IEST DTE 022 Working Group Recommendation have also contributed to the huge momentum MIMO testing has gained in the past decade.
Read MoreAnalyzing the modal parameters of a structure is crucial in optimizing the mechanical properties of the test object. The natural frequencies, damping and mode shapes of the unit under test help in adjusting the design of the test structure which ultimately improves the structural behavior of the test unit.
Read MoreDuring 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 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.
