Technical Field

The invention belongs to the field of semi-physical simulation, and particularly relates to a semi-physical simulation power-on device and method based on overload activation of a start-control missile.

Background

At present, the measurement of angular velocity information after the launching of a highly overloaded launching weapon (such as an artillery and a tank gun) is a well-recognized problem. The main reasons for this are that the angular velocity sensor is hard to be impacted by the high overload environment, and the damage to the sensor by the high overload process mainly has two ways: the direct impact of inertia force and the damage of stress wave generated by high overload to the structure. During the launching process, the cannonball is subjected to huge overload action to accelerate to the expected initial launching speed, the amplitude peak value of the overload process can reach over 20000g (g is gravity acceleration, the same applies below), and the action time is within tens of milliseconds. For example, a 155mm howitzer produces a maximum overload pulse amplitude of 20000g during firing for a duration of 5 ms. The method for adding the inertial guidance module in the cannonball can provide a reference for ballistic correction, and effectively improves the hitting precision of ammunition. Therefore, many developed countries have developed guidance upgrades for conventional ammunition, developing related inertial guidance modules. Among them, the united states advanced research program office (DARPA) lists the anti-high overload gyroscope as one of the key devices in the μ PNT program.

Researches find that the anti-high overload capacity of the sensing device under the condition of no power-on is obviously superior to that under the condition of power-on, and related experiments show that the anti-overload capacity of the sensing device under the condition of power-on is about 5000g, and the anti-overload capacity of the sensing device under the condition of no power-on is about 10000 g. Therefore, in order to solve the influence of high overload on a sensing device, a feasible scheme is to design an overload switch on the missile, when the missile is sensitive to high overload, namely the missile is taken out of a hearth, a thermal battery is electrified, a control system is started, and if the control system is designed to be the scheme, the traditional semi-physical simulation method has infeasible risk. In the traditional semi-physical simulation, a control system is powered on for waiting, and the trajectory is judged to be zero second after an off-line signal is received or the acceleration of a virtual inertial measurement unit sent by a simulator is received, so that control is started; and the missile is provided with an overload switch, and the scheme of starting control of the command control system on the thermal battery by utilizing overload activation cannot be used for powering up in advance, and the precision of starting control time cannot be ensured if a simulator is used for manually powering up. If the power-on starting and controlling time of the overload activation missile needs to be simulated more accurately, a semi-physical simulation power-on device and method for remotely controlling the power supply to be powered on need to be developed.
