This paper argues the necessity of rigorous environmental testing of downhole drilling equipment, particularly focusing on vibration resistance and transportation durability, to ensure high performance and longevity in the field.

Measurements with MIMO shakers will be demonstrated; participant data will be performed using impact testing strategies. Dr. Pete Avitabile, Professor Emeritus at the University of Massachusetts Lowell, will lead the seminar discussions.

We used the Crystal Instruments Spider-80X in conjunction with a Sentek Dynamics M3240A shaker to excite and characterize the mode shapes of a steel plate measuring 24” x 24” x 3/16”.

Sentek Dynamics and Crystal Instruments returned to the 93rd Shock and Vibration Symposium in Atlanta, Georgia. The 2023 Shock and Vibration Symposium attracted an international audience with attendees from the academic, private, and public sectors.

Sentek Dynamics and Crystal Instruments will be attending the 93rd Shock and Vibration Symposium in Atlanta, Georgia from September 25th – 27th, 2023. The Shock and Vibration Symposium brings together an international audience with attendees from the aerospace, nautical, defense, and academic sectors as well as commercial exhibitors.

This article is to list best practices and common mistakes during the operation of an electrodynamic shaker; however, it is not inclusive of all possible situations.

Sentek Dynamics offers comprehensive services and solutions for planning and designing vibration test labs. Our team of engineers has the knowledge and expertise to collaborate with customers and facility managers to ensure successful implementation.

The Canadian Space Agency recently performed the Modal Analysis of a RADARSAT Satellite using five modal shakers. It is important to obtain the modal analysis of the unit-under-test because information about the natural frequencies, damping coefficients and mode shapes can be used to optimize its design and improve its structural behavior.

This article discusses the concept and implementation of a unique safety feature for environmental testing with a focus on Multiple Exciter Single Axis (MESA) vibration testing.

Sentek Dynamics and Crystal Instruments returned to the 69th ESTECH conference hosted by the Institute of Environmental Sciences and Technology (IEST) in St. Paul, Minnesota. The 2023 ESTECH conference attracted attendees from across the vibration testing and controlled environment sectors.

Sentek Dynamics recently shipped its first “Assembled in the USA” vibration testing system. The 32 kN system was assembled with components sourced from foreign and domestic suppliers at our Kannapolis, North Carolina facility. Once the system was assembled, our in-house team put the system through a Factory Acceptance Test (FAT) to ensure compliance with published specifications for a shaker in that size category. This effort confirmed Sentek Dynamics’ capabilities to create parts kits in addition to assembling and testing a final product in North Carolina.

Sentek Dynamics will be attending the Institute of Environmental Sciences and Technology’s (IEST) 69th ESTECH conference in Minneapolis/St. Paul, Minnesota. The annual ESTECH conference serves as a meeting place for professionals in the environmental testing, contamination control, and nanotechnology facilities industries to share insights on emerging technology, developments in best practices, and network with peers across fields.

Sentek Dynamics maintains an extensive inventory of vibration testing systems available for immediate shipment. These systems include various configurations and options for general or specific applications.

Engineering teams can utilize finite element analysis (FEA) to simulate mode shapes, resonant frequencies, stiffness, and strength visualizations to help optimize the structural design and minimize costs. The accuracy of the estimated predictions from FEA is dependent on the assumptions made during modeling and analysis and might vary from real-world test data. This article will cover how to set up an FEA frequency study of a simple flat plate fastened at its center.

Sentek Dynamics returned to the 41st IMAC conference in Austin, Texas. The 2023 IMAC XLI conference attracted an international audience with attendees from the aerospace, defense, and academic sectors as well as 38 commercial exhibitors.

Finite Element Analysis (FEA) frequency simulation allows the user to perform predictive analysis in the design phase and make alterations to the design if any major issues in the design are encountered in the simulation. However, it should be noted that real-world test data of the device should always be used to verify FEA results. A device’s resonant frequencies and mode shapes at those frequencies can be predicted using FEA. In this article, the resonant frequencies of a flat plate will be analyzed.

Rodents find vibration testing system amplifiers an attractive home. Stuart Little and Remy (Ratatouille) were appealing characters in great movies for the family but finding one of their relatives has made a home in your amplifier is not a good situation. Rodents and electrical equipment do not mix. If they do, it typically makes for expensive repairs.

As the leaves begin to change across the Charlotte metro area, Sentek Dynamic’s testing and demonstration facility is looking forward to the arrival of our next advancement in amplifier technology. In the coming months, Sentek Dynamics will be commissioning the largest capacity vibration testing system we have installed at our East Coast facility, and it will be powered by one of our new high-powered amplifiers.
