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 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.

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.

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.

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.

Developing a new product for commercial or defense application may require a wide range of tests to prove the strength and durability of a design. Shock testing is often required to ensure a product can endure the wear and tear it will experience when it is used in the real world.
