PT200 Vibration Analysis Training System Gearbox Prognostics Simulator

VALENIAN-PT200 Vibration Analysis Training System is a multi-functional mechanical fault simulation experimental equipment developed for rotor dynamics of rotating machinery and related scientific research projects in colleges and universities as well as research institutes. This test bench features a simple structure, convenient assembly and disassembly, easy operation and stable performance. It can be flexibly equipped with sensors for measuring mechanical parameters such as vibration, rotational speed, noise and displacement. It can also simulate the vibration state of rotating machinery during transient processes of acceleration and deceleration as well as steady-state operation conditions, and various common faults of rotating machinery, such as rotor dynamic balance test, bearing fault test, rotor misalignment test and mechanical looseness test. In addition, it can be optionally equipped with faulty planetary gear components and conduct fault feature analysis for various common rotating machinery faults.

It can be used with multi-channel data acquisition instruments and analysis software developed by Valenian Company to form a multi-purpose and comprehensive experimental system platform, providing researchers engaged in rotor dynamics and related rotating machinery research projects with a good experimental analysis environment and stable fault signal output.

Experimental research contents:

Carry out experiments to simulate common rotor mechanical faults: such as shaft misalignment, rotor unbalance, rotor rub-impact, and looseness of mechanical foundation.

Research on rolling bearing faults: different fault forms of supporting bearings, such as bearing inner ring fault, bearing outer ring fault, bearing cage fault, bearing rolling element fault, bearing comprehensive fault, etc.

Research on planetary gearbox faults: faults of sun gear, planetary gear and large gear ring, with fault types including missing tooth, wear, broken tooth and crack.
