Universal Modal Test System

• Applicable for modal test excited by hammer and exciter.

• Convenient on the storage management of experimental data named automatically according to modal test and test point Number.

• Obtain signal data easily and effectively with variety trigger modes and different adjustable windows.

• To obtain the best FRF estimation results under excitation, this system provides customers not only a variety of waveform sources including swept sine, narrow-band random and shaped random, but also many kinds of frequency response estimation methods.

• Convenient for the further structure modal analysis, as a result of obtained FRF file supporting varies modal analysis software.

Multi-exciter Modal Test System

• Faced with the increasing complexity of engineering structures. e.g., just based on experience, the design of vehicles and other large complex system isn’t sufficient to meet strict requirements in vibration and noise.

• Accurately getting the structural dynamic characteristics is essential in large and complex structures’ prototype design. Although using finite element analysis software is an economical and practical way. However, in case that one structure is composed of thousand components with various materials and different function, modal test would be the best choice.

• Perfect MISO/MIMO modal test solutions, along with modal analysis software will greatly simplify your work.

Controllable Excitation (pure modal test and step sine test)

• With the unique force control and force limited technology, the vibration controller could not only perform the ordinary multi-degree of freedom vibration test, but also competent in large-scale structure’s modal test, especially the large flexible structure.

• Based on the controllable exciter movement, force control and force limited technology can assure a better balanced energy to structure, and can effectively control the anti-resonance and resonance, thus avoid lack-test and over-test.

• In the modal test, the balanced vibration energy in addition with the amplitude control can reduce the non-linear factors of the structure to the maximum extent, and realize a minimum test result error, eventually obtain the precise modal parameters to be used to build the optimal linear system model.

• This system provides you not only various drive signal of general exciter including a swept sine, white noise, shaped random, etc., but also step sine, dwell and other flexible customized shaker control function.

Online Modal Test System

• UCON is a high performance vibration controller, with real-time DSP processing.

• The perfect combination of vibration control and DAQ and analysis, makes the structural modal test more integrated and efficient.

• UCON vibration controller could control the exciter and acquire responses simultaneously on structure at the same time, and obtain structural FRF synchronously; meanwhile, it could fit the structural frequency response function curve, complete modal testing and analysis.
