Mechanical Vibration Tables: Simple and Reliable Veterans
Mechanical vibration tables are like treadmills in a gym, generating vibration through eccentric wheels or cam mechanisms. These tables are simple in structure, easy to maintain, and suitable for low-frequency, high-load scenarios. They are commonly used in building material testing, agricultural product screening, and other fields, but their vibration frequency and waveform control precision is limited.
Electromagnetic and Hydraulic: Representatives of Precision Control
Electromagnetic: Utilizing the principle of electromagnets, vibration is controlled by current, much like a speaker horn. They have a wide frequency range (5-3000Hz) and are widely used in reliability testing of electronic products.
Hydraulic: Employing a hydraulic servo system, they function like giant hydraulic jacks. Thrust can reach tens of tons, suitable for heavy-duty vibration testing of automotive parts, large structural components, etc.
The Unique Stage of Special Vibration Tables
Piezoelectric vibration tables are like precision watches, using piezoelectric ceramics to achieve micron-level ultra-high frequency vibration (up to 20kHz), specifically designed for optical devices and MEMS sensors. Pneumatic vibration tables are like air cannons, generating impact vibration through pulsed airflow, and are often used for packaging and transportation testing. These two types of special vibration tables play irreplaceable roles in specific fields.
