Integrated damping device for vehicle-mounted inertial navigation system

Abstract

The invention discloses an integrated damping device for a vehicle-mounted inertial navigation system. The integrated damping device comprises a mounting base (10), and the mounting base is elastically connected to a damping plate (30) through a group of damping assemblies (20); each damping assembly comprises a base (21) and a bolt (22); each base comprises a base plate (23); a center hole (24) is formed in each base plate and is perpendicularly connected to a circular tube (25), and each circular tube is sleeved with a lower damping rubber mat (26) and an upper damping rubber mat (27) from bottom to top; the damping plate is clamped between the lower damping rubber mats and the upper damping rubber mats; a cover plate sleeves the top surface of each upper damping rubber mat; and the bolts penetrate through the circular tubes from top to bottom to be connected to the mounting base in a threaded mode. According to the integrated damping device, the overall damping scheme is adopted, the damping device is provided with a reference surface, so that the maintenance is convenient, when a vibration damper is replaced, the damping device can be directly replaced, or only the vibration damper is replaced, after replacement, the inertial navigation system does not need to be calibrated and tested again, and therefore the maintenance workload is greatly reduced, and the reliability of aproduct is improved.

Description

technical field [0001] The invention relates to an integrated damping device for a vehicle-mounted inertial navigation system, belonging to the technical field of damping. Background technique [0002] The vehicle inertial navigation system refers to the device that the vehicle navigation system accurately locates the vehicle body's geographical location, travel speed, the angle between the vehicle body reference plane and the geographic north direction, and the pitch angle and roll angle of the horizontal plane during the driving process of the vehicle body. The vehicle inertial navigation system can guide the vehicle body to drive and provide navigation information in real time. Accurate and fast vehicle inertial navigation system has immeasurable effect and significance in actual use. It can be said that the vehicle-mounted inertial navigation system is the eyes of the vehicle-mounted system, and the vehicle-mounted inertial navigation system finally determines the mobil...

AI Technical Summary

Problems solved by technology

[0004] The local damping device used in the prior art mainly has the following defects: 1. The local vibration damping design of the vehicle-mounted inertial navigation system is complicated and the cost is high

2. The local vibration reduction design is limited by space; the small size of the shock absorber itself makes the vibration reduction effect not obvious

3. The maintenance workload of local vibration damping is heavy, and the replacement of the shock absorber requires a new product calibration test, which brings problems such as heavy maintenance workload and time-consuming

4. Partial shock absorbers are difficult to install and require special tools for maintenance, which is inconvenient

[0005] Therefore, there are still some defects and deficiencies in the local damping device used in the prior art, which needs to be further improved
