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.

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.

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.
