摘要
关节臂式柔性三坐标测量系统是一种新颖的基于旋转关节和转动臂的三坐标测量系统,以角度测量基准取代了长度测量基准,它具有量程大、体积小、重量轻及使用灵活等优点．首先基于Denavit-Hartenberg方法建立了关节臂式柔性三坐标测量系统的理想数学模型和误差模型,并通过几何作图法对模型进行了验证.根据系统的特点和通过对系统中实际存在的影响测量结果的各种误差因素进行了详细分析,为进一步研究系统的误差补偿提供了理论基础．
The articulated arm flexible CMM （coordinate measuring machine） is a new type of CMM with rotational joints and flexible arms, in which lineal measurements are substituted by angular ones. It possesses the advantages of large measuring range, small volume, low weight and portability. By using Denavit-Hartenberg analysis arithmetic, the ideal mathematical model and error model of the articulated arm CMM are established. The feasibility of the models is verified by sketching. All error sources are deeply analyzed according to the traits of the system, which establishes a theoretic base for introducing error compensation.
