KRD70 Hydraulic Vibration Shaker

Name: KRD70 Hydraulic Vibration Shaker
Brand: CME Technology Co., Ltd.

KRD70 series hydraulic vibration shaker is an electronic hydraulic servo vibration test machine with the advantages of fast response speed, high anti-load rigidity, flexible control mode, high performance, and high reliability.

The hydraulic vibration shaker is a device that converts and amplifies the energy of the electro-hydraulic servo valve and converts the energy of the high-pressure liquid into a dynamic test system for the reciprocating motion of the simple actuator. Similar to the function of the electric hydraulic vibration table, it can complete the functions of sinusoidal vibration, random vibration, transient shock, and road spectrum simulation. KRD70 series hydraulic vibration shaker is widely utilized for all kinds of products in aviation, marine, automotive, earthquake, packaging, transportation, and other industries. The vibration shaker system complies with the standard MIL STD-810, ASTM D4728, IEC 60068-2, and ISTA relevant standards.

COMPOSITION OF KRD70 HYDRAULIC VIBRATION SHAKER

KRD70 hydraulic vibration shaker system includes a hydraulic vibration table, control cabinet, and oil source system.

KRD70 hydraulic vibration table is mainly composed of a 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 is controlled remotely by a computer.
