Description
Technical field: [0001] The invention relates to a test system for the transmission inertia of electromechanical equipment, in particular to a test system for the transmission inertia of rotating bodies of rotating equipment in all electromechanical equipment. Background technique: [0002] The total transmission inertia of rotating electromechanical equipment is part of the measurement of quality characteristic parameters and an important parameter in the performance analysis of equipment systems. Its accuracy is directly related to the quality, performance and safety of transmission equipment. At present, some commonly used test methods have certain limitations for complete machine systems such as rotating electromechanical equipment. For example, the torsional vibration method, the parallel line suspension method, and the falling object observation method are only suitable for measuring small irregular bodies, and are not suitable for large irregular bodies.
