The application discloses a digital twin system construction method and device, electronic equipment and a storage medium, and relates to the technical field of electronic information. The method comprises the following steps: acquiring system description data corresponding to a target system; the target system comprises a plurality of nodes which are connected to each other in communication; performing analysis and processing on the node behaviors based on the system description data by using a twin system analysis model to obtain a node behavior model of each node; the node behavior model is used for indicating the node configuration and the node behavior of the corresponding node; instantiating a virtual node corresponding to each node in a virtual digital system; and configuring the virtual node corresponding to each node based on the node behavior model of each node to obtain a target digital twin system corresponding to the target system. According to the method, the cost and difficulty of constructing the target digital twin system are reduced.

This invention discloses a method and mold for cryogenic pressure forming of a large, high-strength cylindrical ring structure, relating to the field of metal sheet forming technology. The forming method includes: Step 1, determining the initial dimensions of the cylindrical ring blank and the required forming temperature based on the shape, size, and performance indicators of the target cylindrical ring structure; Step 2, cutting the flat plate, rolling and welding it into a straight-walled cylindrical ring blank; Step 3, placing the cylindrical ring blank in a mold, filling the space between the cylindrical ring blank wall and the mold with a cryogenic medium and applying pressure, causing the cylindrical ring blank to undergo plastic deformation under cryogenic conditions until it adheres to the mold surface, thus obtaining a cylindrical ring structure with weld seam reinforcement consistent with the base material. The solution provided by this invention can improve the performance and manufacturing efficiency of large cylindrical ring structures and reduce manufacturing costs.

The utility model discloses a bending-adjustable microcatheter handle and a bending-adjustable microcatheter, and belongs to the technical field of medical instruments, the bending-adjustable microcatheter handle comprises a traction wire and a Y-shaped seat, the Y-shaped seat comprises a main branch tube and a side branch tube intersecting with the axis of the main branch tube, one end of the traction wire sequentially penetrates through the main branch tube and is fixedly connected with the end part of the side branch tube, and the other end of the traction wire is fixedly connected with the handle. The other end is fixedly connected with a component connected with the far end of the main branch pipe; a rotating handle rotating cap and a push-pull device are arranged on a bottom pipe of a side branch pipe to be matched with a traction wire, so that the push-pull device moves back and forth in the axial direction of the bottom pipe, and then a fixing buckle connected with the traction wire in a push-pull shell is pushed backwards to complete the bending adjustment action of the traction wire. The utility model further discloses an adjustable bending micro catheter. The handle avoids the situations of wire clamping, wire winding and difficult straightening of the far-end adjustable bent pipe body, and has the advantages of being simple in structure, convenient and fast to operate, low in cost, easy to assemble and high in utilization rate.
