Abstract: A reclosing switch capable of stably opening and closing, including a bracket, a permanent magnet moving core, a driving member, a linkage assembly, a limit assembly, an opening assembly and a contact mechanism. The permanent magnet moving core is configured to provide a force to drive a magnet to move axially along the permanent magnet moving core. When closing the switch, the driving member applies a pressure to the linkage assembly to drive the limit assembly to limit driving member. The opening assembly is configured to provide a force to push the limit assembly to reset, so as to release the driving member. The magnet is provided with a transmission member for connection with the contact mechanism. The contact mechanism is configured to contact with contacts in the switch.

Abstract: A sound absorption apparatus includes a sound absorption unit. The sound absorption unit includes: a connection member including a first connection surface and a second connection surface arranged opposite to the first connection surface, the first connection surface and the second connection surface being parallel to a flow direction of a cooling air flow, and the cooling air flow being an air flow flowing through the sound absorption unit; and a plurality of sound absorption members each being permeable and including: a third connection surface configured to connect to one of the first connection surface and the second connection surface; and a sound absorption surface surrounding the one of the first connection surface and the second connection surface.

Abstract: A multi-objective optimization method and system for a master production plan of casting parallel workshops belonging to a casting, producing, and scheduling fields are provided. In the method and the system, discrete coding is adopted, and parallel scheduling information is directly converted into discrete particles. Through crossing and mutation of each particle together with non-dominated particles in a global optimal solution set and individual optimal solution sets, a quick search of a solution space is completed. Congestion distances of non-dominated individuals in the solution space are calculated, sorting is performed according to congestion, and a new population is generated to allow the solutions to be uniformly distributed.
