1、S曲線無碳小車設(shè)計I摘要S曲線無碳小車來自全國大學生工程訓練綜合能力競賽命題，本文通過認真分析任務要求，確定小車應有的功能，完成了方案設(shè)計、技術(shù)設(shè)計和加工裝配調(diào)試三個階段，制作出了行駛平穩(wěn)輕巧，效率高且轉(zhuǎn)彎半徑、周期可調(diào)的小車，并提出了提高零件精度和增加賽道校準裝置的改進方向。在方案設(shè)計中，根據(jù)功能性需求，小車按模塊化設(shè)計可分為六個部分：車架、原動機構(gòu)、傳動機構(gòu)、轉(zhuǎn)向機構(gòu)、驅(qū)動系統(tǒng)、微調(diào)機構(gòu)，對每個部分采用擴展性思維尋求多種可行方案，并綜合考慮功能實現(xiàn)、加工裝配、成本可行性等因素進行優(yōu)化設(shè)計。其中，車架為骨架式玻纖板，原動機構(gòu)采用滑輪組和變
2、徑繞線軸、轉(zhuǎn)向機構(gòu)采用關(guān)節(jié)軸承連接的曲柄連桿機構(gòu)、驅(qū)動系統(tǒng)采用單輪差速、微調(diào)機構(gòu)采用細螺紋調(diào)節(jié)搖桿與連桿長度以及微調(diào)圓盤調(diào)節(jié)曲柄長度。在技術(shù)設(shè)計中，采用現(xiàn)代機械設(shè)計方法，通過MATLAB建模做能耗規(guī)律和運動學分析，設(shè)計關(guān)鍵參數(shù)，并使用SolidWorks仿真分析，繪制圖紙。關(guān)鍵詞模塊化設(shè)計，matlab建模，solidworks仿真，曲柄連桿機構(gòu)，單輪差速沈陽工程學院畢業(yè)設(shè)計（論文）IIAbstractThenon-carboncarofScurveisfromthenationalcomprehensiveabilitytrainingc
