【摘要】：隨著科學(xué)技術(shù)的不斷進(jìn)步,人們對生產(chǎn)生活中自動(dòng)化水平的要求顯著提高,真空吸盤類機(jī)器人、機(jī)械手和大功率吸附設(shè)備作為自動(dòng)吸附裝備的主要部件,在科學(xué)研究、工業(yè)生產(chǎn)、軍事偵察和物流運(yùn)輸?shù)阮I(lǐng)域極大的提高了作業(yè)效率和精度。此外,在世界各國工農(nóng)業(yè)生產(chǎn)和百姓的日常工作生活中,新能源和清潔能源的使用引起越來越多的關(guān)注,并且快速普及開來。而真空吸附設(shè)備作為清潔能源的典型代表,將其使用性能進(jìn)行優(yōu)化開發(fā),對于推廣清潔能源戰(zhàn)略,具有十分重要的意義。仿生學(xué)作為一門新興的模仿生物高超本領(lǐng)的學(xué)科,對于生物的結(jié)構(gòu)仿生和形態(tài)仿生已經(jīng)取得了許多優(yōu)秀的仿生成果,極大的豐富和便利了我們?nèi)粘５墓ぷ骱蜕�。在掌握國�?nèi)外真空吸盤研究現(xiàn)狀的基礎(chǔ)上,從仿生學(xué)角度出發(fā),選取了具有極佳吸附性能的海洋生物皺紋盤鮑為仿生原型,對其進(jìn)行研究試驗(yàn):分別應(yīng)用體視顯微鏡、掃描電子顯微鏡對皺紋盤鮑腹足的生物形態(tài)進(jìn)行觀測,得出腹足具有功能分區(qū)結(jié)構(gòu),腹足表面分布有直徑為0.5μm、長度為3.5μm、密度為55根/μm2的剛毛;使用拉伸試驗(yàn)機(jī)測量皺紋盤鮑對于不同材料和不同結(jié)構(gòu)形態(tài)接觸面的吸附力,分析得出腹足吸附力來自于范德華力、毛細(xì)力和真空負(fù)壓力;利用高速攝像機(jī)對皺紋盤鮑吸脫附及爬壁運(yùn)動(dòng)中腹足形態(tài)變化進(jìn)行觀測,得出鮑魚腹足抑制脫附的形態(tài)特征,總結(jié)出提高鮑魚吸附性能的結(jié)構(gòu)要素,發(fā)現(xiàn)鮑魚腹足表面上具有多處規(guī)律的褶皺結(jié)構(gòu),對于提升腹足的吸附效果起到重要作用。根據(jù)真空吸盤的使用原理和機(jī)械設(shè)計(jì)理論,結(jié)合鮑魚提高吸附性能的結(jié)構(gòu)要素,對現(xiàn)有真空吸盤結(jié)構(gòu)進(jìn)行仿生優(yōu)化設(shè)計(jì)與建模,使用3D打印機(jī)進(jìn)行柔性材料和剛性材料相結(jié)合的仿生吸盤制造,利用拉伸試驗(yàn)機(jī),對比測試標(biāo)準(zhǔn)吸盤和仿生吸盤的吸附效果。結(jié)果表明仿生吸盤較標(biāo)準(zhǔn)吸盤吸附力提高62.54%,提升效果明顯,意味著仿生結(jié)構(gòu)對真空吸盤使用中的吸附性和穩(wěn)定性有著積極的促進(jìn)作用。利用有限元ANSYS Workbench對工作狀態(tài)下的標(biāo)準(zhǔn)吸盤和仿生吸盤進(jìn)行受力分析,得出仿生吸盤表面的非光滑結(jié)構(gòu)使作用在吸盤頂端的拉力出現(xiàn)應(yīng)力集中,能夠改變作用在吸盤表面的應(yīng)力方向,使作用在吸盤底端邊緣的應(yīng)力減小,對脫附拉力起到抑制作用,從而增強(qiáng)仿生吸盤的吸附性能。
[Abstract]:With the continuous progress of science and technology, people on the level of automation in the production and life significantly improved, vacuum suction robot manipulator and large power equipment as the main component of the automatic adsorption adsorption equipment, industrial production in scientific research, military reconnaissance, logistics and transport and other fields has greatly improved the working efficiency and accuracy. In addition, in the world of industrial and agricultural production and people's daily life, the use of new energy and clean energy has attracted more and more attention, and quickly spread. And vacuum adsorption equipment as a typical representative of clean energy, the use of performance to optimize the development, for the promotion of clean energy strategy, it has very important significance. Bionics as an emerging discipline that mimic biological prowess, the bionic structure and bionic biology has made many excellent bionic The results, rich and great convenience to our daily life and work. Based on the domestic and foreign research status of vacuum chuck, from the view of bionics, the adsorption with the excellent marine abalone as the bionic prototype, experimental study on the application of stereo microscope respectively, biological morphology of Haliotis Bao Gasteropod scanning electron microscope observation, the gastropod has the structure function partition, the distribution of gastropod surface has a diameter of 0.5 m, the length is 3.5 m, the root density is 55 / m2 setae; using tensile test machine to measure abalone for different materials and different structure forms the contact surface adsorption capacity analysis from adsorption force from the Yu Fandehua force, capillary force and vacuum negative pressure; using high speed camera to abalone desorption and change of wall motion in form of climbing gastropods were observed, the abalone belly The morphological characteristics of the foot on the process, summed up to improve the structural elements of the adsorption properties of abalone, found the fold structure has many rules on the surface of the gastropod abalone, to enhance the adsorption effect of gastropods play an important role. According to the principle and mechanical design theory of vacuum sucker, combined with improved adsorption properties of structural elements of abalone, bionic optimization design and modeling of the existing vacuum sucker structure, bionic sucker using 3D printer of flexible material and rigid material combination of manufacturing, using tensile test machine, the adsorption effect of contrast test standard sucker and bionic sucker. The results show that the bionic sucker suction force is increased by 62.54% compared with the standard, enhance the effect, means with bionic structure positive effects on the absorption and stability of vacuum chuck is used. By using the finite element ANSYS Workbench standard of working condition The stress analysis of sucker and sucker bionic, non smooth structure makes the effect appeared in the top of the suction tension stress concentration that can change the surface of bionic sucker, sucker in surface stress direction, the effect of reducing stress on the edge of the bottom end of the sucker, the inhibiting effect on the desorption force, thereby enhancing the adsorption the performance of the bionic sucker.
