Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] The moment gyroscope restoring moment test bench structure of the present invention is as follows figure 1 As shown, its main components include locking block 1, static torque sensor 2, bearing seat Ⅰ3, flange connection plate Ⅰ4, torque gyro 5, torque gyro mounting frame 6, flange connection plate Ⅱ7, bearing seat Ⅱ8, iron foundation 9, torque Gyro controller 10 , computer 11 , data collector 12 , static torque sensor connection flange 13 , and locking adapter plate 14 . The specific structure is described as follows.

[0030] The torque gyro mounting frame 6 is used to rigidly fix the torque gyro 5 to be measured; in actual design, the torque gyro 5 is first fixed on the mounting base by bolts, and then the mounting base is rigidly fixed on the torque gyro mounting frame 6 by bolts. The transmission shaft I is arranged on the beari...

Abstract

The invention discloses a moment gyroscope restoring moment test bench and a measuring method. A locking mechanism, a static torque sensor, a bearing seat I, a moment gyroscope mounting rack and a bearing seat II are sequentially arranged on a base, a transmission shaft I is arranged on the bearing seat I, and one side of the moment gyroscope mounting rack is connected with one end of the transmission shaft I through a flange disc I; the static torque sensor is connected with a static torque sensor connecting flange, and the other end of the transmission shaft I is connected with the static torque sensor connecting flange; the static torque sensor is connected with the locking mechanism; and the other side of the moment gyroscope mounting frame is connected with a transmission shaft II on a bearing seat II through a flange disc II. The computer is connected with the moment gyroscope to be measured through the moment gyroscope controller, and the output of the static torque sensor is connected with the computer through the data collector. According to the test bench, the restoring moment of the moment gyroscope under various working conditions can be rapidly measured at low cost, so that accurate and reliable test data are provided for design and development of the moment gyroscope.

Description

technical field [0001] The invention relates to the verification of the functionality of a moment gyroscope. More specifically, the invention relates to a moment gyroscope recovery moment test bench and a measuring method, belonging to the technical field of automobile testing. Background technique [0002] With the continuous development of automobiles, people have more requirements and expectations for the driving experience of automobiles, especially the high requirements for speed experience and safety functions. Due to the increasing number of cars in the country, the highway mileage is as high as 4.8465 million kilometers, and the traffic conditions are becoming more and more complex, resulting in frequent traffic accidents. In 2019 alone, there were 247,646 traffic accidents. Among the many causes of traffic accidents, rollover is an extremely serious and dangerous working condition, which can be caused by one or a series of comprehensive factors, and can occur on lev...
