Lifting force self-adapting control system of lifting mechanism of missile hanging vehicle and control method

Abstract

The invention provides a lifting force self-adapting control system of a lifting mechanism of a missile hanging vehicle and a control method. A pressure sensor is arranged in a hydraulic transmissionsystem, and the weight of a to-be-hung missile is indirectly measured by collecting the pressure of a hydraulic oil cylinder. A proportional overflow valve is arranged in the hydraulic transmission system, and the maximum working pressure of the hydraulic system is controlled by adjusting the magnitude of gained electricity of a proportional electromagnet in the proportional overflow valve. A controller is arranged in the lifting force self-adapting control system, and the controller collects a dynamic signal of the pressure sensor and the electricity gaining situation of an electromagnetic reversing valve to dynamically adjust the magnitude of the gained electricity of the proportional electromagnet in the proportional overflow valve according to a certain control rate so as to achieve self-adapting setting of the maximum working pressure of the hydraulic system. The weights of different missiles can be detected and recognized automatically, the lifting force of the lifting mechanismof the missile hanging vehicle is dynamically adjusted according to the missile hanging requirement, thus, self-adapting adjustment of the lifting force of the lifting mechanism is achieved, and the purpose of hanging the missile safely is achieved.

Description

technical field [0001] The invention relates to the technical field of a lifting mechanism of a bomb-trapping vehicle, in particular to an adaptive control system and a control method for a lifting force of a lifting mechanism of a bomb-trapping vehicle. Background technique [0002] When the lifting mechanism of the bomb trailer hangs the missile into the launcher, the lifting mechanism of the bomber not only needs to overcome the weight of the missile and the weight of the clamp, but also needs to overcome the spring force of the hook of the launcher. The adaptive control of the lifting force of the lifting mechanism of the bomb trailer is to control the maximum contact force between the guided missile and the launcher, so as to avoid damage to the launcher or the aircraft caused by excessive jacking force. The key technical difficulty is that the system needs to automatically identify the weight of different missiles and dynamically control the maximum lifting force of th...

Problems solved by technology

[0003] At present, due to the different weights of the missiles attached to the bomb vehicle, the existing bomb vehicle can only limit the maximum lifting force, and the maximum lifting force of the lifting mechanism of the bomb vehicle is often limited by setting a safety valve in the hydraulic system , in fact, the lifting force of the lifting mechanism of the bomb trailer is composed of the weight of the missile, the weight of the clamp, and the spring force of the launcher hook. In this relationship, the weight of the clamp and the spring force of the launcher hook are constant. The weight of the missiles is different, which leads to the difference in the excess lifting force of the lifting mechanism, that is, the contact force between the missile and the launcher is different. When the light-weight missile is mounted on the hanging vehicle, the excess lifting force of the system is also the largest, and this value often exceeds that of the missile and the launcher. The range required by the carrier aircraft has a large potential safety hazard, and this problem further limits the use of automatic bomb-loading vehicles in weapon mounting
