电热激发的主动拆卸结构设计

The Design Method of Active Disassembly Structure Using Electro and Heat Stimulation

基于ADSM的主动拆卸驱动部件及其产品,传统的热激发方法(如水浴或空气浴加热)均为加热整个产品,能耗较高,加热时间长,而且加热时可能损害产品的零部件。电热激发作为主动拆卸结构的激发方法,实现主动拆卸结构所述连接部位的连接关系失效,大幅度的提高了电子产品在生命周期终端的拆卸效率,降低了产品零部件的回收成本。电热激发属于局部加热激发,由于能量集中,加热时间短,激发所需的能耗低,激发对产品其它零部件的热损伤很小。文中给出了电热激发法的原理,提出了基于电热激发的主动拆卸驱动部件和主动拆卸卡扣的设计方法,通过有限元分析软件对主动拆卸卡扣温度场的模拟计算,提出了主动拆卸卡扣所需电热片或电热丝功率的选择方法。

For active disassembly driving components and products based on active disassembly using smart mate rials （ADSM） , the traditional heating stimulated methods are heating the whole product. Such as water bath and air bath, they are high energy consumption and the heating time are too long, what is more, products components may be damaged. Electro and heat method as stimulated method of active disassembly structure, connections of active disas sembly structure will become invalid, and disassembly efficiency is improved by a large margin in lifecycle terminal for electronics, and cost-recovering is reduced. Electro and heat stimulated method is local heating stimulated method, by reason of concentration of energy and short heating time, by electro and heat stimulated method requires less energy consumption, by electro and heat stimulated method, heat-damage of other parts for the products is very small. Introducing the principle of electro and heat stimulated method. Presenting the design of active disassembly driver components and active disassembly snaps based on electro and heat stimulation. Temprature fields of Active disassembly snap-fit is simulated by finite element （FE） simulation, and choice method of electric heater bands or heating wire power is put forward.
