【摘要】：本課題根據(jù)公司產(chǎn)品開發(fā)計(jì)劃和市場(chǎng)需求,旨在研發(fā)一種新型直臂式蜘蛛型高空作業(yè)平臺(tái),使我公司繼續(xù)保持在平臺(tái)產(chǎn)品領(lǐng)域的國(guó)內(nèi)領(lǐng)航地位,開拓更廣闊的市場(chǎng)。 本文首先對(duì)國(guó)內(nèi)外先進(jìn)機(jī)型底盤技術(shù)進(jìn)行研究分析,然后結(jié)合實(shí)際項(xiàng)目的設(shè)計(jì)需要,設(shè)計(jì)出蜘蛛型高空作業(yè)平臺(tái)履帶式底盤底架和蜘蛛式支腿。根據(jù)相關(guān)標(biāo)準(zhǔn),計(jì)算支腿反力,并運(yùn)用MATLAB軟件繪制了支腿反力變化規(guī)律曲線。結(jié)果表明：當(dāng)整機(jī)處于經(jīng)常使用的工作區(qū)域內(nèi)(支腿擺角6=45°)時(shí),支腿受到的反力值均大于0,與國(guó)標(biāo)GB/T9465-2008中對(duì)支腿反力大于0的整機(jī)穩(wěn)定性要求相符合。支腿反力小于0的工作區(qū)問比較特殊,屬于狹窄區(qū)域特殊支撐,可以通過加強(qiáng)電控方面的設(shè)計(jì)從而限制工作平臺(tái)工作范圍,禁止進(jìn)入該區(qū)域工作,使整機(jī)工作安全,滿足穩(wěn)定性要求。 在支腿反力分析計(jì)算的基礎(chǔ)上,確定了履帶式底盤底架受力的典型工況和蜘蛛支腿的受力危險(xiǎn)工況,然后對(duì)履帶式底盤底架和蜘蛛式支腿進(jìn)行結(jié)構(gòu)靜強(qiáng)度分析計(jì)算。對(duì)底盤底架和蜘蛛式支腿用ANSYS有限元軟件進(jìn)行建模、網(wǎng)格劃分、邊界條件處理、求解等,得到了底架和支腿的應(yīng)力云圖和位移云圖。結(jié)果表明：底架和支腿在強(qiáng)度方面達(dá)到了設(shè)計(jì)要求,其結(jié)構(gòu)設(shè)計(jì)也是合理的。為最終設(shè)計(jì)出適應(yīng)性強(qiáng)、滿足設(shè)計(jì)要求的直臂式蜘蛛型高空作業(yè)平臺(tái)底盤和公司系列化產(chǎn)品的開發(fā)提供參考依據(jù)。 應(yīng)用電測(cè)量方法對(duì)直臀式蜘蛛型高空作來平臺(tái)底架和支腿結(jié)構(gòu)進(jìn)行應(yīng)力測(cè)試,得到較為準(zhǔn)確的應(yīng)力值。為驗(yàn)證有限元分析計(jì)算結(jié)果的正確與否,將應(yīng)力測(cè)試結(jié)果與有限元分析計(jì)算結(jié)果進(jìn)行了對(duì)比。結(jié)果表明：底架和支腿強(qiáng)度符合設(shè)計(jì)要求,對(duì)底架和支腿的靜力學(xué)分析結(jié)果正確、方法可行,為進(jìn)一步完善結(jié)構(gòu)和優(yōu)化設(shè)計(jì)提供參考依據(jù)。
[Abstract]:According to the company's product development plan and market demand, this project aims to develop a new type of straight arm spider aerial work platform, so that our company can continue to maintain its domestic navigation status in the platform product field and open up a broader market. In this paper, the chassis technology of advanced models at home and abroad is studied and analyzed, and then the crawler chassis and spider leg are designed according to the design requirements of actual projects. According to the relevant standards, the reaction force of the leg is calculated, and the curve of the law of the reaction force of the leg is drawn by using MATLAB software. The results show that when the whole machine is in the working area which is often used (the swing angle of the leg is 645 擄), the reaction force of the leg is greater than 0, which is consistent with the stability requirement of the whole machine in GB / T / 9465-2008 when the reaction force of the leg is greater than 0. The working area where the reaction force of the leg is less than 0 is special and belongs to the special support in the narrow area. It can limit the working range of the working platform by strengthening the design of electric control, and prohibit the work from entering the area, so as to make the whole machine work safely. Meet the stability requirements. Based on the analysis and calculation of the reaction force of the supporting leg, the typical working conditions of the crawler chassis and the dangerous condition of the spider supporting leg are determined, and then the structural static strength analysis and calculation of the crawler chassis and the spider supporting leg are carried out. The bottom frame and spider leg are modeled by ANSYS finite element software, the grid is divided, the boundary condition is treated and solved, and the stress cloud diagram and displacement cloud diagram of the underframe and the supporting leg are obtained. The results show that the underframe and leg reach the design requirements in strength, and the structure design is reasonable. It provides a reference basis for the design of the chassis of the vertical arm spider type aerial work platform and the series products of the company which have strong adaptability and meet the design requirements. The electric measurement method is used to measure the stress of the platform underframe and the supporting leg structure of the straight hip spider type high altitude working platform, and the more accurate stress values are obtained. In order to verify the correctness of the finite element analysis results, the stress test results are compared with the finite element analysis results. The results show that the strength of the underframe and the supporting leg meet the design requirements, the results of statics analysis of the underframe and the supporting leg are correct, and the method is feasible, which provides a reference for further improving the structure and optimizing the design.
