Abstract
The invention provides a micro mechanical gyroscope swinging testing device which comprises mechanical device part and control part; wherein the mechanical device comprises: machine base on which is provided with a circle dick supporting axial and guide arm supporting axial; a circle disk installed on the circle disk supporting axial with a driven wheel under the circle disk and balls fixed on the circle disk; a guide arm and an objective table on the guide arm supporting axial, the guide arm being provided with a guide rail stop slot which has balls placed in it; the control part includes a direct current torque motor with a speed governor, which is installed on the machine base and has a drive wheel installed on its output axial, the drive wheel and driven wheel are connected by belt. The guide arm swing forth and back when the circle disk and balls rotate with uniform velocity, and the swing angle changes approximate sine rule, the frequency and amplitude of the angular velocity are controlled by controller and can be measured via a standard gyroscope fixed on the object table.
Description
(1) technical field
What the present invention relates to is a kind of proving installation, and specifically a kind of often use in the test of micromechanical gyro is used to provide the proving installation by the angular velocity signal of sinusoidal rule variation.
(2) background technology
Need to provide angular velocity signal in the performance test of micromechanical gyro with test table.Test table is the main testing apparatus that detects and estimate gyrosystem, utilize turntable to study to gyrosystem, set up mathematical model, identify performances such as its scaling factor, precision, sensitivity, find out the various drift factors of gyro by different test methods, process compensates in inertial navigation system, thereby improves the precision of system.
The test table that uses is mainly used in the test of traditional gyro at present, the main air-bearing that adopts, alternating current torque motor directly drives, form angle measuring system with inductosyn and rotary transformer, traditional test table mechanical realization complexity, bulky, difficulty of processing is big, cost an arm and a leg, use inconvenience.
(3) summary of the invention
The purpose of this invention is to provide a kind ofly provide that signal is accurate, swing arm type tester for micromechanical gyro that controllability is strong, good stability, simple to operate, being used in the micromechanical gyro test of being easy to process provide angular velocity signal carries out the angular velocity test to micromechanical gyro.
The object of the present invention is achieved like this: it comprises mechanical hook-up part and control section, wherein mechanical hook-up comprises base, disk back shaft and guide rod supports axle are installed on base, on the disk back shaft disk is installed, under disk, engaged wheel is set, be fixed with ball on the disk, guide rod and objective table are installed on the guide rod supports axle, have the guide rail stopper slot on the guide rod, ball places the guide rail stopper slot, and control section is the direct current torque motor that has speed regulator, and direct current torque motor is installed on the base, on its output shaft driving wheel is installed, is connected by belt between driving wheel and the engaged wheel.
The present invention can also comprise:
The distance in the axle center of the length of guide rod much larger than ball to the disk back shaft.
Disk of the present invention is fixed on the base by the disk back shaft, fixes a ball on disk plane, and guide rod is fixed on the base by the guide rod supports axle.Direct current torque motor drives the disk uniform rotation by belt pulley, and speed regulator is regulated motor speed.Ball places the guide rail stopper slot of guide rod, is driven the simple harmonic motion of making reciprocally swinging by disk.Wherein the length of the guide rail stopper slot in the guide rod should be greater than the diameter of disk, and width equals ball diameter and can make ball free movement in guide rail.Ball at the uniform velocity rotates along disk back shaft axle center, and its radius of turn is much smaller than guide rod length.
The invention has the advantages that: 1, provide signal accurate; 2, good stability is easy to control; 3, simple in structure, be convenient to processing, simple to operate.
