&

Three-axis Six DoF Vibration Assembly(

The vibration assembly uses compressed air as power source and consists of an exciter, a vibration table and a support system.

The HC-30o0 controller is designed specifically for Highly Accelerated Life Testing (HALT) and Stress Screening (HAss). It integrates control, signal acquisition,and analysis functions. The system preciselymanages air hammer force, liquid nitrogen flow, and electric heating. It also offers accurate temperature measurement and broadband random spectrum analysis.

Comparedto single-stresstests,itofers more realistic environmentalsimulationand higher testing efficiency.

Wide Application

Itis usedinerospace,specialvehicles,andotherindustries toevaluateandcertifythereliabilityanddaptability of electronic products.It also helps identify design and process defects earlyin the development stage.

The Vibration Shaker Works Stably

The vibration shaker features a full sealed design with adjustable internal air pressure to counteract suction forces caused by pressre changes in the test chamber.This ensures the armature remains centered and the shaker operates smoothly.

Note:

1.Water supply temperature:Water temperature of 5 ^ { \circ } { \mathsf { C } } { ~ } 2 8 ^ { \circ } { \mathsf { C } } can meet the usage requirements.Water temperature of 2 8 ^ { \circ } { \mathsf { C } } { ~ } 3 3 ^ { \circ } { \mathsf { C } } can be used normally, but the cooling time will vary.
2.The specifications of the vibration table can be customized.
3.Overllibdtt be slightly adjusted due to differences in compressor configuration.
