Title:
METHOD, APPARATUS AND SYSTEM FOR MONITORING TORSIONAL VIBRATION OF SHAFT SYSTEM OF LEAF SPRING DAMPER
Document Type and Number:
WIPO Patent Application WO/2024/001209
Kind Code:
A1
Abstract:
A method, apparatus and system for monitoring torsional vibration of a shaft system of a leaf spring damper. The method comprises: acquiring torsional vibration amplitude test values of an inner ring hub (2) and an outer ring inertia loop (3) of a leaf spring damper at different loads and rotation speeds, and on this basis, constructing a torsional vibration amplitude relationship library of the inner ring hub (2) and the outer ring inertia loop (3) at the same load and rotation speed; and acquiring a torsional vibration amplitude monitoring value of the outer ring inertia loop (3) and the current corresponding load and rotation speed, and on this basis, according to the torsional vibration amplitude relationship library, obtaining a torsional vibration amplitude monitoring value of the inner ring hub (2) at the current load and rotation speed. A torsional vibration amplitude relationship between an inner ring hub (2) and an outer ring inertia loop (3) at the same load and rotation speed is established, and thus a torsional vibration amplitude of the inner ring hub (2) is derived by means of monitoring a torsional vibration amplitude of the outer ring inertia loop (3), such that the actual torsional vibration condition of a shaft system is reflected, and safety monitoring and risk early warning are performed. Further disclosed are an electronic device and a computer-readable storage medium.
