Research And Development Of Training-Simulation Test Bed Of Self-Propelled Artillery Hydraulic System

Self-propelled artillery is one of the main combating weapons on modern battlefield. With the development of technology, hydraulic technology has become one of the most important means of the realization of the modernization of artillery. In order to ensure that self-propelled artillery hydraulic system being in good operational condition, it is particularly necessary for ordnance officers to strengthen the operation of simulating and training on the hydraulic system of artillery. So a training-simulation test bed of self-propelled artillery hydraulic system is developed, which can greatly improve the learner's understanding of the principles of artillery hydraulic system and the actual practical ability. At the same time it avoids training on real vehical, which can reduce training costs and extend the life span of equipments.In the thesis the training-simulation test bed of self-propelled artillery hydraulic system is developed through software and hardware design. The technical requirements which the test bed needing to be achieved are analyzed and a program to achieve this goal is established. First, using configuration software MCGS(Monitor and Control Generated System), the operational configuration interface windows and animation windows of artillery hydraulic system, oil source, automatically transporting shells, saving power mechanism, all kinds of failure settings and database connection are established. In the use of rich graphical and monitoring capabilities of configuration software, a real time observation of piston's displacement, velocity and pressure of system can be achieved. Also we can make a fault diagnosis in the system. Then PLC controlling system is designed and the communications link between PLC and PC are achieved, which leads MCGS to interconnect with external devices. So a real-time simulation between hardware and software systems can be realized. Finally, a modeling research and correction of closed-loop servo controlling system of automatically transporting shells'velocity is established and RC network is used to compensate it, which reduce the resonant peaks and improve the accuracy of the controlling system.The demonstrating results showed that the design of the training-simulation test bed is reasonable. The operating results of test bed's monitoring configuration interface are lifelike. The configuration monitoring system can receive controlling signals emitted by PLC, which can be reflected on the computer screen in accordance with the procedures of the algorithm in the means of animation, number, text, ruler and other forms. It can simulate the hydraulic system components'movement when artillery in a working state. And we are able to see movement of actual hardware of hydraulic system and the status of various signals through computer screen, which can greatly facilitate the ordnance officers to train, operate and demonstrate on the hydraulic system of self-propelled artillery. Therefore, the training -simulation test bed has some practical and applied value in military schools.
