A device and method for simultaneously measuring the comprehensive static stiffness of lin-ear guideway were proposed and designed.The structure design and sensor displacement of this device were introduced,and the theoretical model for the device was set up to solve of composite static stiff-ness.The simultaneous measurement of five kinds static stiffness was realized by the equivalent de-composition of the deformation and eccentric load.Additionally,the main errors of the device were analyzed,and the experimental steps were studied out.The device and method of this experiment will improve the efficiency of the static stiffness test for linear guide.
