Researches On The Dynamic Simulating For Experiment System Of Artillery Traction And Running

Experiment in vibrating condition is an effective means to simulate running state and test quality for artillery. The experiment system designed and researched in this thesis achieves artillery rolling as well as vibrating by simple roller as the road signal given by relative criterion. And it can simulate the running condition of artillery dynamically. The whole system is composed by serval parts, which include the mechanical structure and transmittion system, the hydraulic servo and hydraulic vibrating-exciting system, the electrical driving and variable frequence speed regulating system, as well as the computer measuring and controlling system. The experiment system is symmetrical and it can carry out long extent as heavy load. In this thesis, the finite element analysis is used to check the mechanical structure of the system, applied to do static analysis and modal analysis for vibrating test table. The servo system is also analyzed and proofreaded by MATLAB and digital PID controller. The vibrating-exciting action is realized by hydraulic servo system in high frequence and large quantity of flux. Tri-phase AC induction motor is used as the driving power for roller system. PWM variable frequence speed regulation is applied for motor speed control. Industrial PC and data acquisition card are employed as the key unit of measuring and controlling system. The selection, principle and adguestment of the sensors and data acquisition cards are also investigated in this thesis. The nati-disturbence of measuring and controlling system is designed by means of hardware and software. The whole system is a typical advanced integration of mechanical, hydraulic and electrical techniques.
