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.
