Quadrantal point motion simulation stand

Abstract

In order to solve the problems of large volume, complicated control process, high manufacture cost and inconvenience in maintenance of an existing quadrantal point motion simulation stand, the invention provides a quadrantal point motion simulation stand which comprises a bracket and a crank-connecting link-sliding block mechanism, wherein the bracket is divided into two layers which are parallel with a horizontal plane, the bottom layer is provided with a motor and a speed reducing mechanism connected with the motor, the top layer is provided with a crank-connecting link-sliding block mechanism, one end of a crank structure in the crank-connecting link-sliding block mechanism is fixedly connected with an output shaft of the speed reducing mechanism, a sliding block structure is connected with the crank structure through a connecting link structure, effective link lengths of the crank mechanism and the connecting link structure are same, the sliding block structure comprises an equipment installing platform and a linear bearing, and the linear bearing is matched with a sliding rail. By using the quadrantal point motion simulation stand, more accurate test conditions can be provided for a quadrantal point motion test of a gyroscopic compass for a ship; and the quadrantal point motion simulation stand is low in manufacture cost and maintenance cost, and more remarkable in practicability and accuracy.

Description

technical field [0001] The invention relates to a motion test of a ship's compass in the ship industry, in particular to a test device for a corner point motion test in a type approval test of a gyro compass. Background technique [0002] According to maritime regulations, every seagoing ship must be equipped with a gyro compass. As one of the navigation electronic systems, the gyro compass can provide true heading information for the ship. The gyro compass is used in the field of navigation, so its test should meet the requirements of international standards such as "SOLAS Convention", "IEC 60945", "ISO 8728", "IMO A.694". Among them, the "ISO 8728" specification serves as the basis for the type approval test of marine gyrocompass products, and even more rigidly stipulates that marine gyrocompasses must undergo corner motion tests and meet the requirements. [0003] The corner motion represents the real motion of the ship, so the purpose of the corner motion test is to dy...
