Abstract: A method and system for inspecting deviation in dynamic characteristics of a feeding system are provided, and the method includes: exciting the feeding system and detecting vibrations of a subcomponent of a component to be inspected of the feeding system to generate a monitoring excitation signal in a monitoring mode; calculating, by a modal analysis method, monitoring eigenvalues and monitoring eigenvectors of the monitoring excitation signal; determining, by a modal verification method, similarity between the monitoring eigenvalues and standard eigenvalues of a digital twin model and similarity between the monitoring eigenvectors and standard eigenvectors of the digital twin model; determining that the dynamic characteristics of the subcomponent are deviated, when the monitoring eigenvalues and monitoring eigenvectors are not similar to the standard eigenvalues and standard eigenvectors. Therefore, the subcomponent whose dynamic characteristics are deviated can be sensed remotely and precisely.

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 clamp slide for use in a linear guide includes a slide body, two piston units disposed in the slide body, two elastic members stopped against the piston units, and two fluid pressure cylinders pushing the piston units to move toward a direction against restoring forces exerted by the elastic members. Further, a moveable member is disposed in each of the piston units and pushed by an inclined plane of a lateral cover to push a braking member, such that a rail is clamped by the left and right braking members. The lateral cover can be assembled in different ways according to actual needs for enabling the inclined plane to perform opposite tilt direction. As such, the clamp slide of the present invention has the effects of simplifying structure and reducing cost.
