Sensors for Modal and Structural Analysis

Analyze and define the dynamic properties of structures with Dytran modal analysis sensors. Dytran offers high-quality uniaxial and triaxial accelerometers for monitoring small, medium or large structures.

Applications

  • Small Structures: Since smaller structures resonate at higher frequencies, it is important to use accelerometers with low mass to avoid mass loading the structure. Dytran offers a variety of low-mass accelerometers that are ideal for modal and structural analysis of small structures.
  • Medium Structures: These structures require accelerometers with a wide frequency response and high sensitivity. Dytran offers a variety of single-axis and triaxial accelerometers that are well-suited for modal and structural analysis of medium structures.
  • Large Structures: Since larger structures resonate at lower frequencies and lower amplitudes, it is important to use accelerometers with high sensitivity and low noise. Dytran offers a variety of high-sensitivity accelerometers that are ideal for modal and structural analysis of large structures.
  • Forcing Function/Impulse Hammers: Dytran dynamic force sensors and impedance heads are important tools for determining the input force parameters at the driving point when exciting a structure with a modal shaker. These rugged and reliable sensors are ideal for both lab and industrial environments. Dytran also offers the industry's broadest range of impulse hammers to cover almost any size test article, from small structures like turbine blades and castings to large structures like ships and bridges. The hammers are designed with interchangeable impact tips of various durometers, allowing structural engineers and dynamicists to determine the correct combination of pulse width and frequency content of the forcing function to efficiently excite all the modes of a test article or structure.
