1、小型四足機(jī)器人的機(jī)械設(shè)計(jì)與仿真摘要四足機(jī)器人有很強(qiáng)的環(huán)境適應(yīng)性和運(yùn)動(dòng)靈活性,可廣泛運(yùn)用于搶險(xiǎn)救災(zāi)、排雷、探險(xiǎn)、娛樂、及軍事等領(lǐng)域,因此,對(duì)四足機(jī)器人的研究已經(jīng)成為機(jī)器人研究領(lǐng)域的重要課題。本文介紹了一種能實(shí)現(xiàn)前方探測(cè)功能的小型四足機(jī)器狗的機(jī)械設(shè)計(jì)與仿真過程。論文的主要內(nèi)容包括:1.簡(jiǎn)要分析了國(guó)內(nèi)外四足機(jī)器人的發(fā)展現(xiàn)狀和趨勢(shì)。2.根據(jù)要實(shí)現(xiàn)的功能對(duì)機(jī)器狗進(jìn)行整體機(jī)械設(shè)計(jì)與關(guān)鍵部位的優(yōu)化。3.采用三維造型軟件Solidworks建立四足機(jī)器狗的本體結(jié)構(gòu),然后在保持模型質(zhì)量、質(zhì)心位置和轉(zhuǎn)動(dòng)慣量等物理信息和幾何信息不變的條件下,對(duì)模型進(jìn)行簡(jiǎn)化,便于仿真。4.采用Parasolid文件傳輸標(biāo)準(zhǔn)
2、,利用ADAMS的專業(yè)圖形接口模塊ADAMS/Exchange,把在SolidWorks環(huán)境下建立的簡(jiǎn)化后的模型導(dǎo)入ADAMS/View中。在ADAMS/View環(huán)境下,根據(jù)實(shí)際情況添加相應(yīng)的約束、驅(qū)動(dòng)和力。然后進(jìn)行仿真,并將仿真過程保存在AVI格式的電影文件。關(guān)鍵字:四足機(jī)器狗,機(jī)械設(shè)計(jì),SolidWorks,ADAMS,仿真48AbstractThequadrupedrobot,whichhasadvantagesofgoodsurroundingadaptabilityandhighmoveagility,isappliedtoagreatdealoffieldssuchasr
