What is a modal test system?
Modal analysis is an analysis that determines the frequency at which the object itself is likely to vibrate and its vibration shape. Also called eigenvalue analysis. Modal Test combines data collection and analysis. The entire process is sometimes referred to as modal Test and analysis, or experimental modal analysis (EMA).

Modal Exciter
VE-M seriesFrequency up to 10,000Hz, excitation force up to 1,000N Ideal for modal excitation
The VE-M series exciter is a broadband Modal Exciter, with an excitation force range of 100 to 1,000N and a frequency range of DC to 10,000Hz. Due to the small lateral vibration and large axial vibration stress, multi-directional vibration in the vertical and horizontal directions can be realized, and it is stable and reliable, making it ideal for modal analysis.
Modal analysis is primarily used to determine the structural properties of a target product, such as natural frequencies, damping ratios, and modal shapes. The ultimate goal is to provide a reference and basis for the analysis of vibration characteristics, system fault diagnosis and prediction, and optimization of structural dynamic properties.
This modal analysis system consists of a Modal Exciter or force hammer, test instruments, acceleration pickup and power amplifier, analysis software, etc., and has charac teristics such as high efficiency and good portability.
Features-Exciter
・ Wide frequency band, small size, large excitation force, strong rigidity
・ The length of the vibration rod can be adjusted through the movable part through-hole, and the clamp position can also be adjusted, making it easy to connect to the test sample.
・ Electronic zero position control allows for adjustable axial stiffness, with little need for additional stiffness to the test sample
・ Stroke length can reach 25.4mm, making it ideal for structural tests that require suspension of various rigid structures and Modal Exciters at low frequencies.
