Abstract: A nanofriction power generation device with spiral vibrating balls and a buoy body thereof-includes an inner spiral barrel, an outer spiral barrel sleeved outside the inner spiral barrel, hollow balls between the two spiral barrels, an electric energy storage device contained in the inner spiral barrel, and a buoy barrel for containing the outer spiral barrel. The outer wall of the inner spiral barrel and the inner wall of the outer spiral barrel are respectively provided with first spiral tracks and second spiral tracks extending from one end to the opposite other end. The inner spiral barrel is in the outer spiral barrel, and the first spiral tracks and the second spiral tracks have a one-to-one correspondence and form spiral channels. Nanofriction electric generator films are attached to an outer surface of each hollow ball and an inner wall of each spiral channel.

Abstract: The present invention discloses a method and system for determining a maintenance policy of a complex forming device. The method and system include: establishing a performance judgement standard; obtaining actual operation data; and determining a performance stage of the complex forming device, and determining the maintenance policy of the complex forming device. The establishing a performance judgement standard includes allocating data located at different performance stages to corresponding working condition units; setting data located at a normal performance stage to normal reference data, and calculating, by using a shortest path algorithm, distances between operation data of different working condition units in different functional modules and the normal reference data, to obtain performance statuses of the different functional modules. In view of this, by using the method and system provided in the present invention, a suitable maintenance policy can be selected for the complex forming device, thereby reducing maintenance costs.
