| 摘 要： | 以大型直线感应加速器为例，采用时程分析法对大型加速器在强烈振动环境下的结构响应进行了数值计算；同时对加速器关键点位置的偏移量进行了测量。数值计算结果表明在加速器中段存在2 mm左右的变形，在此段的实测结果为对中偏移量0.6 mm左右，位移2 mm左右。在对数值计算数据和测量数据分析的基础上，利用校正设备实现了加速器机械轴的对中，使机械轴的直线性偏差在±0.2 mm以内。分析表明，数值计算结果对于测量点布置、现场检测及测量数据分析具有预测和参考作用。 |

| Abstract: | Take the Dragon-Ⅰ accelerator as an example, the structure response under strong vibration has been calculated using time history analysis method for the large scale accelerator, and the offsets of key points on the accelerator were measured. Numerical results show that there is 2 mm deformation in the middle of the accelerator, and in this segment the measured alignment offset is about 0.6 mm, and the measured displacement is about 2 mm. Based on the analysis of numerical calculation and measurement, the linear deviation of mechanical axis is less than ±0.2 mm after alignment. The analysis show that the calculation results can provide references for measuring point arrangement, on-site inspection and measurement data analysis. |
