摘要： A method and device for testing a positioning and speed measuring system main unit. The method includes: obtaining a first simulation signal by simulating an absolute position sensor and a relative position sensor; sending the first simulation signal to a main unit of a to-be-tested positioning and speed measuring system; obtaining a first result calculated by the main unit based on the first simulation signal; obtaining a second result calculated based on the first simulation signal, the second result being a reference result corresponding to the first simulation signal; and determining that the main unit is abnormal if a comparison between the first result and the second result exceeds a first preset range. Therefore, the main unit can still be tested without components including absolute position sensors and relative position sensors, the test process is simple and easy to implement, a test environment can be built without large-scale investment.

摘要： A linear motor comprises a primary part and a secondary part opposite to each other. An air gap is reserved between the primary and secondary parts. The air gap has first spacing in non-operating state and second spacing in operating state. The side surface of the primary part facing the secondary part is provided with a magnetically conductive film that has elasticity in the thickness direction and a thickness greater than the first spacing and less than the second spacing. The magnetically conductive film comprises magnetically conductive base bodies and non-magnetically conductive base bodies alternately distributed along the surface of the magnetically conductive film, and the magnetically conductive base bodies are filled with magnetically conductive materials. The magnetically conductive base bodies cover magnetic poles on the side surface of the primary part facing the secondary part, and the non-magnetically conductive base bodies shield gaps between the adjacent magnetic poles.

摘要： An active control anti-yaw damper (100) is provided. When a piston (2) of the active control anti-yaw damper (100) reciprocates inside a hydraulic cylinder (1), an interior of the hydraulic cylinder (1) is divided into two cylinder blocks (PA, PB) which communicate with an oil reservoir through two main oil lines respectively to form a primary loop between the hydraulic cylinder (1) and the oil reservoir; a reversing valve (PV3) is installed between the two main oil lines and the oil reservoir and is configured to change a flow direction of the primary loop when the active control anti-yaw damper (100) is in an active mode and adjust a displacement of the piston (2) within the hydraulic cylinder (1).
