【摘要】 为满足EAST装置实验性能和真空室安装空间的要求,EAST ECRH天线系统的平面镜转动机构采用的是发射环向角和发射极向角驱动控制存在耦合的连杆结构形式。为此计算了平面镜转动机构驱动结构的参数关系,包括驱动电机与平面镜转动角的关系式,以及平面镜转动角与微波发射角的关系式,画出了对应的关系曲线,并且进行了微波发射位置的测定实验。实验结果显示计算出的一系列参数关系式能够描述微波的发射位置,可以作为驱动控制设计的理论基础,能满足EAST装置的实验要求。更多还原

【Abstract】 A structure that the driving control of toroidal and poloidal angle are coupled has been used to meet the needs of experiment performance and the installation space of vacuum chamber on the plane mirror’s rotating mechanism in EAST ECRH antenna. Thus the parameter relationships of this rotating mechanism have been calculated, including the relationship of driving motor’s movement and mirror’s rotation angle and the relationship of mirror’s rotation angle and microwave’s emitting angle. And the relation curves were also given. In addition, determination experiment has been carried out to mark the actual position of emitting microwave, which showed these parameter relationships are consistent with the emitting position, and can be the theoretical foundation of driving control designing.更多还原
