摘　　要：介绍了一种三辊定心辊的机构解析计算方法,采用两次三角形解析的方法求解了双摇杆机构的主动摇杆转动角度和从动摇杆转动角度的公式,解析了3个定心辊的作用圆的几何中心坐标值的计算公式,使用推导出的公式对一套三辊定心辊机构进行了计算验证。该计算方法为定心设备的设计开发与验证带来便利。Described in the paper is an analytical calculation method for the three-roller steadier for CTP.The formulas for the separate rotation angles of the drive rocker and the driven rocker of the dual-rocker mechanism are solved via the triangle analysis inelhod,and thus the calculation formula for the geometric center coordinate values of the acting circles of the three centering rollers are analyzed,and the deduced formula is used for calculation-verification of the three centering rollers.The said calculation method shall facilitate the design development and verification of the centering device.
