【摘要】 在分析三维非轴对称薄壁管件旋压成形机床工作过程的基础上,利用MATLAB软件中SIMULINK模块对该机床的液压系统进行了建模与仿真。仿真结果与实验结果相吻合,结果表明,由比例流量阀、位移传感器和放大器共同构成的闭环控制系统能较好地满足三维非轴对称零件旋压成形工艺要求,从而为进一步进行系统的液压和机械系统的协同仿真,提供了客观可靠的理论基础。更多还原

【Abstract】 Based on the procedure analysis of the spinning machine for 3D non-axisymmetrical thin-walled tubes, modeling and simulation of the machine is established by means of the SIMULINK module of the MATLAB software. The simulation results conform well to the experimental ones, it shows that the closed loop system consisted of the flow ratio valve, displacement sensor and amplifier can meet the demand of the 3D non-axisymmetrical part spinning forming satisfactorily. Therefore, it provides an objective rational theoretical foundation for further co-simulation of the hydraulic and the mechanical systems.更多还原
