Abstract: It is a teaching system for remote hydraulic experiments based on combination of virtual and real, belonging to the field of teaching application. In the virtual simulation teaching system for remote hydraulic experiments based on combination of virtual and real, the virtual and real combination part involves that a hydraulic circuit is simulated by a student by remotely calling the Automation Studio software on the experimental platform, the hydraulic circuit is modified and optimized according to the idea of the student, and the hydraulic experimental platform is connected finally to perform actual operations. The system is also added with a network HD ball machine, a network video recorder, a switch, a ball machine bracket, a router and other devices to form a feedback system, so the student can observe the real-time operation of the hydraulic experimental platform through the feedback system.

Abstract: A zero-Poisson-ratio honeycomb structure and an interlocking assembly manufacturing method thereof are provided. The honeycomb structure is formed by combining a four-pointed star shaped structure and horizontal and vertical honeycomb wall arrays at star corners. The zero-Poisson-ratio honeycomb structure not only has the zero-Poisson-ratio characteristic, but also can achieve respective design of in-plane and out-of-plane mechanical properties. Meanwhile, due to the existence of the horizontal honeycomb walls and the vertical honeycomb walls, the connection of multiple honeycomb walls at angular points in the honeycomb structure is avoided. Moreover, a novel manufacturing mode is provided for the honeycomb structure in addition to prepare the honeycomb structure by utilizing a 3D printing process. The honeycomb structure can be manufactured by combining an interlocking assembly process with resin matrix composites. The performance of the honeycomb structure is further improved at the material level.
