Vibration System

Structure composition

The excitation rod uses an elongated flexible steel rod as the core component, with integrated fixing devices at both ends, forming a channel for transmitting axial force.

Core functions

Force transmission characteristics

• Axial force transmission: efficiently transmits the axial excitation force generated by the exciter;

• Transverse decoupling: significantly attenuates the transverse component through the flexible rod design (typical attenuation rate >90%);

Measurement optimization

• Eliminate cross-sensitivity of unidirectional force sensors to transverse forces;

• Suppress random noise in test signal (signal-to-noise ratio improved ≥15dB);

System protection

• Mechanical isolation between the moving coil and the specimen : reduces transient response to shock (e.g. ringing effect during step excitation);

• Protection mechanism: prevents deformation of the moving coil winding or overload of the specimen caused by abnormal excitation;

Typical application

• S&R evaluation and other external/environmental noise sensitivity tests;

• Durability and NVH testing of structural parts;

• Quality testing for sensor production;

• Verification of laboratory instruments;
