Structural Dynamics Testing and Analysis
We offer a one-stop solution for structural dynamics testing to analyze the dynamic behavior of structures subjected to dynamic (high acceleration) loading. The solution is ideal for optimizing your products' dynamic properties and behavior – from initial concept to final certification and beyond, including troubleshooting and structural health monitoring.
Our solution covers various applications such as the modal test (OMA, ODS and MIMO), FFT - Frequency Response Function, fatigue test analysis, SRS - Shock Response Spectrum, sine reduction (COLA), and structural and bridge health monitoring.
To understand a structure’s behavior, we need to analyze the way it reacts to loads and forces. By exciting the structure with an impact hammer or vibration shaker and measuring its response with accelerometers, you can characterize its modes and natural resonant frequencies.
Our solution combines very flexible data acquisition hardware and award-winning Dewesoft X DAQ software. Both fully integrated offer the most precise vibration measurement with an unmatched signal to noise ratio - more than 130 dB, and dynamic range up to 160 dB. Our engineers go the extra mile to make the structural dynamics software easy to use.
Sine Reduction Test - Sine Processing With COLA Signal
Integrate and synchronize the data acquisition system seamlessly with your vibration shaker COLA signal and perform a powerful evaluation of structural properties on unlimited channels in real-time. The Dewesoft sine processing solution is easy to set up and will get you measuring right away.
Modal test is indispensable tool to determine natural frequencies and mode shapes of any structure. Dewesoft offers easy to use operation with short time for setup while offering rich visualization and animation of results.
Shock Response Spectrum - SRS
Mechanical shock pulses are often analyzed in terms of the shock response spectrum. The shock response spectrum assumes that the shock pulse is applied as a base input to an array of independent single-degree-of-freedom systems.
Dewesoft data acquisition systems are used in structural health and seismic bridge monitoring projects ranging from structural mechanics to continuous monitoring of large, complex structures. The systems provide distributed, high-channel-count and remote monitoring for highway overpasses, roads, buildings, and bridges.
