Abstract: Provided is a multifunctional structure for electrical energy and mechanical environment management, which comprises a main structure module, four rechargeable/dischargeable power source modules (PSMs), a vibration reduction system and a sensor module. The main structure module includes a framework, an upper cover plate and a lower cover plate. Elastic blocks are arranged between the periphery of each PSM and walls of the square cavity used for accommodating the PSM. Elastic cushions are arranged between the bottom surface of each PSM and the lower cover plate, and between the top surface of each PSM and the upper cover plate. The multifunctional structure, by means of embedding the PSMs into the interior of the structure, can realize high integration of multiple functions, such as bearing, power supply and vibration reduction, and can greatly improve the load/mass ratio, the load/volume ratio and the function/structure ratio of a system platform.

Abstract: A solid-state polymer lithium battery pack and a preparation method therefor are provided. The lithium battery pack includes: single batteries (1), connecting sleeve members (2), electric cables (3), a battery box (4) and a pouring sealant, and has functions of power supply, power storage and multiple charging/discharging. The preparation method includes: connecting a plurality of single batteries in series by means of connecting sleeve members (2) to form combined batteries; connecting a plurality of combined batteries in series to form a lithium battery pack; and finally, assembling the lithium battery pack into a battery box (4), filling a pouring sealant inside the battery box by means of a sealant pouring process for fixing the single batteries (1) and internal electric cables (3), and discharging air in the battery box (4), so that a final solid-state polymer lithium battery pack is obtained.

Abstract: A non-limit multi-function viscoelastic support structure group, relating to a field of aerospace structural design, includes a basic structure, a supported structure and multiple viscoelastic support structure units. The multiple viscoelastic support structure units form a circular discontinuous group and are arranged between the basic structure and the supported structure. The viscoelastic support structure units are connected with the basic structure and the supported structure respectively in ways of pre-pressing and surface contact, and no fixed constrained relationship exists. The present invention absorbs a vibration energy through a viscoelastic effect of own structural material and forms a spring-oscillator vibration attenuation system with the supported structure.
