Abstract:

Active disassembly structures are usually triggered by single physical field. These structures can be triggered automatically in extreme or accidental circumstances, thus causing the low reliability of products. For improving the reliability of active disassembly products, this paper expounded the triggering mechanism and characteristics of active disassembly structure triggered by temperature-pressure coupling, and studied the design principles and methods of active disassembly structure triggered by temperature-pressure coupling. The feasibility of these design methods was proved by a case analysis. The results show that the reliability of active disassembly structures triggered by temperature-pressure coupling is improved greatly.

Key words: active disassembly, multi field coupling, parallel triggering, design method

摘要：

目前的主动拆卸结构的拆解一般应用单一物理场激发,在极端环境或意外环境中可能会发生主动拆解,产品可靠性不高,针对此，研究了温度-压强耦合并行激发主动拆卸结构的激发原理和特点，提出了温度-压强耦合并行激发主动拆卸结构的设计方法，并通过案例分析，验证了该设计方法的可行性。研究结果表明:应用温度-压强耦合并行激发的主动拆卸结构作为连接单元的产品,其可靠性大幅度提高。
