摘　要:為了實現三坐標測量機的最佳動態測量精度，介紹了接觸式測頭的工作原理，研究了測頭動態特性與測量機動態測量精度之間的復雜關系，提出了測頭動態有效作用直徑的概念。利用實驗分析了測量機運動DCC參數對測頭動態有效作用直徑的影響，結果表明：測量機測頭逼近距離對作用直徑的影響遠遠大于觸測速度和移動速度對作用直徑的影響，而移動速度對作用直徑的影響最小。[著者文摘]

Research on Dynamic Characteristic of CMM ProbeLiu Yong Yang HongtaoLiu Yong Yang HongtaoAbstract:To implement the optimal dynamic measuring precision of CMM,the measurement principle of the contacted probe is introduced. The complex relationship between the dynamic characteristics of probe and dynamic measurement precision of CMM is researched, and the concept of dynamic effective functional diameter of the probe is proposed. The influences of the DCC parameters of CMM on the dynamic effective functional diameter of probe is analyzed by the experiments. The results of the experiments show that the approaching distance has more effect on the functional diameter change than the probing and moving velocity of the probe, and the moving velocity has the least effect on the change.[著者文摘]
