【摘要】：為攻克常規(guī)防滑輪胎在冰面上通過性低的難題,以馴鹿足為仿生原型,對馴鹿足底特征形貌進行分析。該文通過逆向工程技術(shù),將馴鹿足單個足底劃分為內(nèi)、外側(cè)邊緣曲線、脊線凹槽面和足跟凸冠面4個典型部位。運用1st Op軟件和MATLAB軟件對特征部位擬合并構(gòu)建數(shù)學(xué)模型,利用X射線能譜儀對馴鹿足底特征部位進行元素分析。內(nèi)、外側(cè)邊緣曲線方程的決定系數(shù)R~2分別為0.994、0.992;脊線凹槽面和足跟凸冠面曲面方程的R~2分別為0.96、0.98。通過模型驗證發(fā)現(xiàn),模型擬合值與實際值的相對誤差均值在5%以下,實現(xiàn)了馴鹿足底特征形貌從生物模型到數(shù)學(xué)模型的轉(zhuǎn)化。能譜分析結(jié)果表明馴鹿足底除含有大量的碳、氧及氮元素外,硫、硅、鐵、鋁、鈣5種元素含量較高,并且不同部位的元素存在差別。該研究可為工程仿生技術(shù)應(yīng)用于冰路面行駛車輛胎面設(shè)計提供新的研究方向和參考依據(jù)。
[Abstract]:In order to overcome the problem that the conventional non-skid tire has low transmissivity on the ice surface, the characteristic morphology of the sole of reindeer foot is analyzed by using reindeer foot as bionic prototype. In this paper, the single sole of reindeer foot is divided into inner and outer edge curves by reverse engineering. Four typical parts of ridge grooves and calcaneal protrusions were constructed using 1st Op software and MATLAB software to construct mathematical model of characteristic parts, and elemental analysis of characteristic parts of sole of reindeer was carried out by X-ray energy spectrometer. The determination coefficient of the lateral edge curve equation is 0.994 / 0.992, and the rout _ 2 of the ridge groove surface and heel crown surface equation is 0.96 ~ 0.98 respectively. It is found that the relative error between the model fitting value and the actual value is less than 5%, through the verification of the model, the relative error between the model fitting value and the actual value is less than 5%. The transformation of reindeer sole features from biological model to mathematical model was realized. The results of energy spectrum analysis showed that in addition to a large number of carbon, oxygen and nitrogen elements, sulfur, silicon, iron, aluminum and calcium were higher in the sole of reindeer. The research can provide a new research direction and reference for the application of Yu Bing pavement tread design.
