KRD70 hydraulic vibration table is mainly composed of table supporting mechanism, electro-hydraulic servo valve, actuator, working table, guide mechanism, oil filter, cooling system, etc.
When the hydraulic vibration test table vibrates vertically, it is driven by the vertical hydrostatic servo cylinder. When the horizontal vibration test is required, the hydrostatic servo cylinder can be turned over 90° and connected to the horizontal slip table to provide the drive. The hydraulic system and control system are controlled remotely by computer.
Hydraulic Station of KRD70 Hydraulic Vibration Shaker
Hydraulic station is a mechanical device that provides power for electro-hydraulic servo test system. It has the characteristics of simple structure, stable working pressure, energy saving and environmental protection, and is widely used in various types of electro-hydraulic servo testing machine.
Control System of KRD70 Hydraulic Vibration Shaker
KRD70 hydraulic vibration shake control system is mainly composed of computer, display, acceleration sensor and digital random vibration controller.
EHC-2000 electro-hydraulic servo control system, integrated motor remote start, automatic oil pressure adjustment, servo control, vibration control, can comprehensively and intuitively display real-time oil pressure, voltage, current, and other alarm information.

FAQ
What Is Vibration Test?
Vibration testing is simulating the vibration environment by the shaker in laboratory, introducing force function into the UUT to test the response of the UUT to a defined vibration environment. Vibration testing is performed to test the product durability, integrity, fatigue life, resonant frequencies.
How to choose different types of vibration shakers?
There are three types of shaker systems-electrodynamic (ED) shaker, servo-hydraulic (hydraulic) shaker and mechanical shaker. The major specifications to consider are frequency range, displacement, acceleration, tested axes, payload and vibration/shock levels, and force rating. Since mechanical shaker can only test sine and was out of date, we discuss the other two types.
For relatively low-frequency vibration (typically less than 200 Hz), servo hydraulic shaker is adopted. Electrodynamic shaker is used for higher frequencies (typically 5 Hz to 2500 Hz). ED shaker's displacement is under 51mm (P-P), while hydraulic shaker can be up to 100mm (P-P). Moreover, if it's a significant force test, the hydraulic shaker will be the cost-effective choice.
How many types of vibration testing waveforms?
- Sine
- Random
- Resonant search & dwell
- Sine on Random
- Random on Random
- Sine & Random on Random
- SRS (Shock Response Spectrum) Analysis
What are the main parameters to determine a vibration test?
To select a suitable shaker to do a vibration test, we should know following parameters: - UUT Size & Weight (including fixture)
- Frequency Range and Waveforms
- Displacement and Acceleration
- Test Direction
- Target Vibration Test Profile
Can a vibration table do shock test?
Yes, if it's the low level (acceleration) and wide pulse duration shock test, e.g.: 4g@50ms, using vibration shaker is the best choice. What's the lowest frequency hydraulic vibration shaker can achieve?
0.1HzHow do I choose vibration test equipment according to ISTA procedure?
Vibration test using the 1-inch fixed displacement method, peak-to-peak, at a predetermined frequency for the ISTA 1A and 1B procedures.
The 1C, 1D and 1E procedures require a vibration test using two alternative methods: fixed linear vertical displacement or random vibration.
Instead, for procedures 1G and 1H, the testing sequence requires a random vibration test. For the 2A and 2B procedures, the testing sequence outlines two testing procedures: the fixed-displacement vibration test and the random vibration test. However, the ISTA 2C procedures require a random vibration test under dynamic load. The ISTA 3A procedure is composed of different types of tests depending on the package to be tested (standard, small, flat or elongated) and its characteristics. In the case of vibration tests, the performance of a random vibration test with or without top load is required for all types of packages. Optionally, a random vibration test at low pressure may be performed.
The ISTA 3B procedure requires the performance of a random vibration test with top load. However, protocols ISTA 3E and 3H also require the performance of a random vibration test, but without top load in this case.
Project 3K requires a random vibration test. A random vibration test with or without top load.
