    Abstract: A method and a system for building digital twin models allow the setting of a shape and dimensions of a simplified geometric solid corresponding to a component of a feeding system; after sampling the solid to obtain second position data, calculates a set of model eigenvalues and a set of model eigenvectors by a modal analysis method according to a material data of the component, the second position data and second size data of the solid; and defines the solid as a digital twin model of the component when it is determined by a modal verification method that a set of actual eigenvectors of the component is similar to the set of model eigenvectors. Data amounts of the second position and size data are far less than data amounts of first position and size data of an image of the component.

    Abstract: A device and a method for detecting states of a linear guideway including a sliding block and a slide rail are provided. The device includes a sensor located at a position corresponding to a side surface of the slide rail, and an analysis processer communicated with the sensor. The sensor detects the vibrating of the slide rail to generate a sensing signal. The analysis processer compares the sensing signal with at least one threshold, to determines occurrence of abnormalities. Therefore, the sensitivity for detection may be increased.

    Abstract: A method of detecting a preload of a linear guide includes: applying an external force to the linear guide with an external force applying device, wherein the external force applying device sends an impact signal while applying the external force; sensing with a sensor a vibration signal sent from the linear guide because of vibration thereof which occurs under the external force; and receiving the impact signal of the external force applying device and the vibration signal of the sensor and calculating the preload of the linear guide according to a received result, with a signal analyzer. Therefore, with the method of the present invention, the preload of the linear guide is precisely tested regardless of environmental factors.
