AI Technical Summary
Existing fan blade vibration testing equipment suffers from problems such as high vibration, high noise, and severe wear of parts when a single lifting seat is raised and lowered cyclically.
The design employs two lifting seats that move synchronously in opposite directions. The lifting seats are driven to move in opposite directions by a drive mechanism, and the synchronous reverse movement of the lifting seats is achieved by using a connecting rod and eccentric wheel structure, thereby reducing vibration and impact.
It reduces equipment operating noise, minimizes component wear, and extends equipment lifespan.
