Abstract

The invention relates to a rigidity measuring device for an integral flexible joint. The device is characterized in that a joint clamp is mounted at one end of a base, and a flexible joint is clampedin the joint clamp; a vertical column is fixedly mounted at the other end of the base; a controller is fixedly installed at the vertical column; a displacement sensor is connected to the controller; ahorizontal measuring rod is connected to the displacement sensor; a mass block is placed on the horizontal measuring rod; a vertical measuring rod is vertically connected to the horizontal measuringrod; a measuring head is vertically arranged at the end of the vertical measuring rod; and the measuring head is placed on a testing point on the upper surface of the flexible joint. The invention also relates to a rigidity measuring method for an integral flexible joint. The device and the method are scientific and reasonable in design, convenient to operate, small in measurement error and high in stability, and improve the measurement precision; the measuring head accurately positions the flexible joint test point, the measurement effect is ensured, and the measuring head is protected to prevent collision and damage in the measurement process.

Description

technical field [0001] The invention belongs to the field of measurement of flexible gyroscope parts, relates to the measurement of the stiffness of a flexible joint, and in particular relates to an integral flexible joint stiffness measurement device and method. Background technique [0002] The flexible gyro strapdown inertial navigation system has been widely used in navigation, aviation, aerospace, military and other fields due to its low manufacturing cost, high performance, and autonomous navigation capabilities in any environment. The system has broad application prospects and great demand, and is the dominant inertial system of tactical weapons. Flexible gyroscopes are very important as sensitive elements in inertial systems. The flexible joint is an important key part of the flexible gyroscope, which is a frictionless elastic support element. The rotor in the gyroscope is connected with the drive shaft by a flexible joint, which transmits the rotational torque of ...
