Product description

The KRD70 series hydraulic vibration shaker converts the energy of high-pressure fluid into reciprocating motion of the cylinder via an electro-hydraulic servo valve. It is especially suitable for low-frequency, high-force vibration tests. The system supports sine, random, and multi-point excitation, as well as shock and mixed-mode tests, including sine-on-random, random-on-random, and resonant search & dwell. It is used to replicate real-world vibration environments experienced by transportation vehicles, bulk-packaged products, mechanical equipment, and electrical and electronic products. This allows users to optimize product structures and reduce costs.

The KRD70 series hydraulic vibration shaker converts high-pressure fluid energy into reciprocating cylinder motion via an electro-hydraulic servo valve. It is especially suitable for low-frequency, high-force vibration tests. The system supports sine, random, and multi-point excitation, as well as mixed-mode tests including sine-on-random, random-on-random, and resonant search & dwell. Vibration testing is essential in transportation engineering, packaging integrity validation, and electromechanical reliability testing to identify structural weaknesses and prevent fatigue failures. The KRD70 series is widely used in automotive, aerospace, rail transit, heavy machinery, large electrical apparatus, and bulk logistics. It replicates real-world vibration environments for transportation vehicles, bulk-packaged products, mechanical equipment, and electrical products, helping optimize product structures and reduce costs. This equipment meets the requirements of ISTA 1/2/3/6 Series, MIL-STD-810H, IEC 60068-2 and ASTM D4728.

To achieve sine vibration, random vibration, multi-point excitation, and shock tests;

It can be used to simulate seismic excitation with low frequency and high force features.

The high-strength cast aluminum or cast magnesium table ensures uniform and consistent vibration, high reproducibility, and avoids deformation of the table.
