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 (FRF - frequency response function, OMA, ODS, SIMO, and MIMO), FFT - Spectrum Analyzer, 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. Dewesoft since processing solution offers a simple setup and real-time calculation of any channel count desirable. All measured and calculation results are visible in real-time. Free award-winning data acquisition software included with lifetime updates.
and FATIGUE Analysis
Fatigue is the progressive and localized structural damage that occurs when a material is subjected to cyclic loading. Continued cycling of high-stress concentrations may eventually cause a crack that propagates and results in leakages.Safety is an important aspect in designing automotive and other components. Dewesoft fatigue analysis solution is used for predicting fatigue damages based on measured strain and stress.
Modal Testing and Modal Analysis
Solution for Structural Testing
Dewesoft modal test and analysis suite is a solution that offers SISO, SIMO, MISO, and MIMO Experimental modal testing (EMA), and Operational Deflection Shapes (ODS) testing, and offers advanced modal analysis features for both EMA and Operational Modal Analysis (OMA) used to estimate modal models. The modal test and analysis are indispensable tools to determine natural frequencies, damping ratios, and mode shapes of any structure. With Dewesoft’s Modal Test, you can excite a structure with an impact hammer or multiple modal shakers and easily measure the responses. Import or draw your geometry with rich visualization and animation of your structures. Dewesoft Modal Analysis extension provides the right tools for you to estimate modal parameters of more complex structures having many closely coupled modes. The system comes with lifetime FREE software updates.
Shock Response Spectrum
SRS Analysis Solution
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. SDOF system assumes that each system hat its own natural frequency.
Structural Health Monitoring of Bridges
Dewesoft data acquisition systems are used in structural health and seismic bridge monitoring projects ranging from structural mechanics to continuous monitoring of large, complex bridge structures. The monitoring systems provide distributed, high-channel-count and remote monitoring for highway overpasses, roads, buildings, and bridges. We provide a total solution from DAQ systems and data loggers to sensors and monitoring software.
