摘　要:本文研究了三坐标测量机在高速测量过程中的动态误差。以一台移动桥式三坐标测量机为例，分析了其动态误差的产生原因，建立了其动态误差的数学模型，并对动态误差进行了全面的测量和补偿。实验证明，三坐标测量机的动态误差具有一定的重复性，可用软件补偿，从而提高三坐标测量机快速测量的精度。[著者文摘]


Study of Compensation for Dynamic Error of CMM in Process of High-speed MeasuringCui Zhouping Zhu ChenghuaCui Zhouping Zhu ChenghuaAbstract:The dynamic errors of three coordinates measuring machine during fast probing are studied in this paper. Taking a moving bridge CMM as example, its dynamic error sources are analyzed, the mathematic model for dynamic error is established and the dynamic errors are measured and compensated completely. Tbe test results show that the repeatability of dynamic errors is good and it can be compensated by software method to enhance the accuracy of the CMM.[著者文摘]
