Sine & Random Vibration Test System With 700kgf Force & 600mm Table

What Application Challenges Do Customers Commonly Encounter During Vibration Testing?

The core challenge of vibration testing is how to realistically simulate the complex environments that products may experience during transportation, flight, or actual operation, such as sine sweep, random vibration, and shock conditions, while ensuring compliance with international standards including GB, GJB, MIL, IEC, and others.

At the same time, many customers are unsure how to select suitable equipment according to their specific test conditions, such as frequency range, acceleration level, and payload requirements.

This solution is based on the core combination of the A07S23 electrodynamic vibration shaker, LA07K digital switching power amplifier, and VCSusb-2 controller, together with the VT60 vertical expansion table and HG60 horizontal slip table. It can fully cover your required 1–4500 Hz sine sweep, random vibration, and shock testing requirements, while providing 700 kgf sine force and a 600 × 600 mm table.

All designs comply with major international standards such as GB, MIL, and IEC, and are equipped with efficient cooling, multiple safety protection functions, and automated report generation features.
