| 中文摘要 |
| 本文根据一次成形封头无胎冷旋压机的工作特点，导出了在旋压过程中保证主轴与成形辊同步旋转的条件。针对液压调速系统存在的问题，提出了由变频电源和鼠笼式交流电机组成的调速驱动方案；研制了以单片机为核心的参数自调整模糊控制系统。经大量的模拟实验后，该控制系统已被成功地应用于∞0.8米一次成形封头无胎冷旋压机中。理论和实践证明，该系统设计正确、简单可靠、具有明显的社会意义和经济效益。 |
| 英文摘要 |
| In this article we derive the necessary conditions which ensure synchronous rotation between the main shaft and forming roll in spinning process according to the features of one-forming of spinning machine without spinning chuck. In order to overcome the shortages of hydraulic system, an adjustable speed system which consists of variable- frequency power and squirrel-cage motor is proposed. Because the dynamic feature of adjustable-speed AC drive system are extremely complicated and the load torque of motor changes in a wide range during pinning process, adjustment of classical control system is much difficult. Thus a parameter self- adjustable fuzzy controller using a single chip computer is designed. The principle of parameter self- adjustable and the roles of proportional constants are analyzed. The step responses of the fuzzy controller and PID controller with different loads are given. After a number of experiments, the system has successfully been used in a one-forming spinning machine ∞0.8m without spinning chuck. It is proved by theory and practice that the design is correct and the system is simple, reliable and inexpensive. |
