Structural Dynamics Analysis and Testing

Modal Testing and Modal Analysis​​​​​​​

Structural dynamics testing and analysis solution

The modal test and modal analysis are indispensable tools to determine natural frequencies, damping ratios, and mode shapes of any structure. With Dewesoft’s modal test solution, you can excite a structure with an impact hammer or multiple modal shakers and easily measure the responses. SISO, SIMO, MISO, and MIMO test configurations are supported. You can import or draw geometry and perform rich visualization and animations. The modal analysis extension provides the tools to estimate modal parameters. 

Dewesoft is an out-of-the-box modal solution for Experimental Modal Testing (EMA), Operational Deflection Shapes (ODS), and Operational Modal Analysis (OMA). The system also comes with lifetime FREE software updates and support.

Flexible averaging. Advanced functions for in-depth frequency analysis. As always, simple configuration and intuitive user interface round up the feature set.

In addition to top performance, the Dewesoft FFT analyzers come with lifetime free software updates, free technical support, and an industry-leading 7-year warranty.

Fatigue Testing

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.

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

Bridge monitoring 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 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.
