    摘要:

    以等強(qiáng)度設(shè)計(jì)思想為指導(dǎo)，以提高聯(lián)合收獲機(jī)清選裝置疲勞壽命、延長使用功效為目標(biāo)，運(yùn)用剛?cè)狁詈蟿?dòng)力學(xué)分析、疲勞壽命分析、裝配尺寸公差分析等方法，通過建立清選篩動(dòng)力學(xué)模型，對(duì)影響聯(lián)合收獲機(jī)清選系統(tǒng)疲勞壽命的因素進(jìn)行研究，獲得影響清選裝置主要零部件疲勞壽命的關(guān)鍵因素。提出一種清選系統(tǒng)疲勞壽命分析方法和優(yōu)化設(shè)計(jì)方法，并通過試驗(yàn)驗(yàn)證了該分析方法的準(zhǔn)確性，仿真與試驗(yàn)應(yīng)力偏差在20%以內(nèi)。

    Abstract:

    Guided by equal strength design ideas, the objective was to improve the fatigue life and prolong the use efficiency of the combine harvester cleaning device by using rigid-flexible coupling dynamics analysis, fatigue life analysis and assembly dimensional tolerance analysis. Through the establishment of the clearing sieve dynamics model, the key factors affecting the fatigue life of the main components of the cleaning device were obtained. The systematic improvement was carried out to improve the fatigue life of the combine harvester cleaning system. A fatigue life analysis method and optimization design method for the cleaning system were proposed. The accuracy of the analysis method was verified by experiments.
