It is difficult to imagine the actual vibration level and distribution from the numerical display or signals, which are basically a mathematical representation of the vibration experienced by the structure under test. Animating the structure’s deformation provides users with a clearer representation of the intensity from vibration.
Read MoreCrystal Instruments is committed to the continuous innovation of our solutions and providing the best user experience possible. By adopting the latest developments in software technology, our team has developed a convenient modern aesthetic in addition to a feature-rich experience for Engineering Data Management (EDM) software, which serves the entire product line.
Read MoreCrystal Instruments is excited to announce the addition of Strain Rate feedback to its arsenal of non-acceleration vibrational control strategies. The Spider-80SG/SGi system now supports the use of strain gauges as the primary control transducers. This feature allows users to define test profiles as a function of strain and frequency.
Read MoreResearch into new-technology batteries has accelerated over the last decade with the promise of energy density being significantly improved. This research has led to more lithium-ion battery applications in aircraft, electric and hybrid vehicles (EVs and HEVs), 2 and 4-wheel light electric vehicles (LEVs) and personal items such as laptops and wearable devices.
Read MoreLithium-ion batteries are gaining popularity as the most common battery type used for electric vehicles. During their lifespan, these batteries undergo a variety of vibrations and temperature changes. Several common test standards have developed to simulate the long-term environmental effects on these batteries across different size levels (e.g. cell, module, pack).
Read MoreBattery packs are one of the two main components relied on by Electric Vehicles (EV) for vital parameters such as speed, mileage, and torque. Hundreds or thousands of battery cells must be combined to provide the demanded voltage and current required to drive electric vehicles (EV).
Read MoreEDM’s Account Management program controls the accessibility of features from different users. This provides a structure for managing the privileges for different groups of users. The Account Manager can be used to prevent lower-level users from adjusting parameters or display settings. It also allows users to customize the toolbars for a simplified user interface. By hiding certain features, the UI can be made much easier to use.
Read MoreCombined vibration testing is gaining prominence due to the advancement of test equipment technology driven by the need to accomplish simultaneous testing of multiple measurement quantities. Vibration testing combined with temperature, humidity or a combination of other quantities has enabled the creation of test environments closely resembling typical scenarios in which DUTs operate.
Read MoreCrystal Instruments recently released version of EDM 8.0 software allows users to view the selected characteristics (e.g., Peak, RMS or Peak to Peak) of a channel versus time for the entire duration of the test. This feature is included in all vibration control tests and allows users to track user-defined characteristics of any channel (including the control signal) for the duration of a test.
Read MoreThe EDM Vibration Visualization feature is available in all modules of EDM software (VCS, DSA and Modal). This option provides fast and efficient structural model generation and full 3D visualization of the online vibration pattern on the structure under test
Read MoreThe Ethernet connection interface is one of the most important features of the 4th generation Spider series vibration controller. It provides the flexibility of location, reduces noise and electrical interference, and uses one PC to monitor multiple controllers.
Read MoreFatigue Damage Spectrum (FDS) allows users to compare the potential damage caused by different Random profiles, swept Sine profiles or a combination of both.
Read MoreIt is not easy for human eyes to see the modal shape at various frequencies. If we can freeze the motion at the desired frequency, we can capture the modal shape created. A stroboscope is a device which flashes light at a resonance frequency of an object to make the object appear stationary.
Read MoreThe new Engineering Data Management software release from Crystal Instruments, EDM 5.1, improves ease of use, performance, and scalability of the associated hardware. The updated software version, introduced approximately 7 months from the previous 5.0 release, features enhancements to the high channel count configuration, as well as Multi-Sine control, Multi-exciter single-control for Sine, Fatigue Damage Spectrum (FDS) in Random, and Transient Random control. The release also supports the brand-new handheld dynamic signal analyzer, Spider-20.
Read MoreCrystal Instruments continued to achieve relevance in wider global markets when the Spider-80X dynamic measurement system received certification from the Russian State Register of Measuring Instruments. The certification was obtained in partnership with Dipaul, Crystal Instruments' Spider-80X Russian distributor, and allows the highly scalable vibration controller and dynamic signal analyzer to be sold in Russia.
