    摘要:

    模仿人類咀嚼系統(tǒng)，利用仿生技術(shù)設(shè)計(jì)了一種用于粉碎食物的仿生咀嚼裝置。采用逆向工程方法設(shè)計(jì)制作了仿生牙齒、仿生顳下頜關(guān)節(jié)等零部件，并組裝成咀嚼裝置，實(shí)現(xiàn)了三維咀嚼運(yùn)動(dòng)，確定了運(yùn)動(dòng)參數(shù)。咀嚼功能測(cè)試結(jié)果表明，本裝置的咬合力可達(dá)到咀嚼食物的力量，并且可根據(jù)食物的不同而改變；本裝置的咀嚼效率和受試者無(wú)顯著差異，最大值可達(dá)92.3%；重復(fù)試驗(yàn)無(wú)顯著差異，本裝置穩(wěn)定可靠。

    Abstract:

    A bionic chewing equipment was developed for food breakdown by simulating the masticatory system and using the bionic technology. Some parts were designed and assembled by reverse engineering method, like bionic teeth and temporomandibular joints. The equipment could realize 3-D chewing motion, the movement parameters were determined. Test of occlusive force showed that chewing force of equipment could break food and change with food. Masticatory experiment showed that masticatory efficiency of the equipment had no significant difference with subjects and its maximum value was 92.3%. The bionic chewing equipment was stable and reliable.
