Description
Technical Field
The invention relates to the technical field of artillery, in particular to an artillery vibration reduction system and method based on a piezoelectric driver and artillery equipment.
Background
At present, artillery equipment such as tanks and warships and provided with artillery generally controls aiming shooting of the artillery by arranging two-degree-of-freedom rotating mechanisms such as a bidirectional stabilizer, so that stability of a shooting angle and shooting direction required by the artillery is guaranteed, and the situation that the artillery equipment vibrates due to topographic fluctuation (such as tank running and warship affected by wind and waves) is avoided from affecting shooting precision.
A two-degree-of-freedom rotation mechanism such as a bidirectional stabilizer mainly relies on a power cylinder and a motor to adjust a firing angle and a firing direction in a wide range, and for example, when a tank moves, a tank body generates longitudinal vibration (for example, longitudinal angular vibration) and vibration in a horizontal direction. For longitudinal vibration, the tank cannon deviates from the given position due to friction in the trunnion and the power cylinder, so that a misalignment angle is generated between the cannon direction and the gyroscope direction, an electric signal in direct proportion to the misalignment angle is generated from an angle sensor converter, and then the electric signal is amplified by an electronic amplifier in the control box; the output end of the electronic amplifier is connected with an electric relay of a power cylinder control mechanism, and the electric relay enables the two oil cavities of the power cylinder to generate pressure difference; the hydraulic oil in the oil supply device enters the power cylinder, and a power cylinder guide rod connected with the artillery moves relative to the cylinder body fixed on the armor plate on the top of the artillery tower under the action of the pressure in an oil cavity of the power cylinder, so that the artillery returns to the position given by the gyroscope. For vibration in the horizontal direction, due to friction in the race of the tank, the turret and artillery of the tank are deviated together from the given position, so that an angle deviation is generated between the direction of the artillery and the direction of the gyroscope, and then an electric signal proportional to the angle deviation is generated from an angle sensor converter, amplified by an electronic amplifier in a control box and transmitted to a direction aiming motor of the tank, so that the turret returns to the given position.
However, when the gun apparatus having a gun such as a tank or a warship adjusts a firing angle and a firing direction in a wide range by the power cylinder and the motor of the bidirectional stabilizer, the gun of the gun apparatus inevitably generates minute vibrations, which affects the firing accuracy of the gun.
