Abstract

The invention belongs to the technical field of rotational inertia measurement, and particularly relates to a rotational inertia measurement device and method. The rotational inertia measurement device comprises a first fixing assembly, a main shaft, a measuring weight, a bearing assembly and a second fixing assembly, one side of the first fixing assembly is used for fixing a motor rotor shaft, one end of the main shaft is connected with the other side of the first fixing assembly, and the other end of the main shaft is provided with a hook. The measuring weight is wound on the main shaft through a connecting rope and hung on the hook, the measuring weight drives the main shaft, the first fixing assembly and the motor rotor to rotate in the free falling process, and the main shaft is arranged in the bearing assembly in a penetrating mode. One side of the second fixing assembly is used for fixing a motor stator, and the other side of the second fixing assembly is connected with the bearing assembly through the adjusting assembly.

Description

technical field [0001] The invention belongs to the technical field of moment of inertia measurement, and in particular relates to a moment of inertia measurement device and a measurement method. Background technique [0002] In the development of diesel engines for mining vehicles and power generation, the motors used to match the complete vehicle are all used for the original vehicle, and its moment of inertia value cannot be obtained. One of the calculation input values, the inaccurate value of the moment of inertia will cause the calculation of the crankshaft to fail, and there will be a problem of crankshaft failure in the subsequent matching of the vehicle. In the process of research and development of diesel engines in the prior art, the rotor is removed and the rotor is measured or the three-dimensional modeling of the rotor is measured by three-dimensional software. However, it is difficult to deal with and measure the case where the moment of inertia of the matchin...
