摘要翻譯--hbt40c-1008d混凝土拖泵液壓系統(tǒng)設計

1、<p><b>　　摘要</b></p><p>　　拖式混凝土泵大量運用于城鎮(zhèn)建設、路橋建設、水利水電、隧道建設等施工現(xiàn)場。隨著在工程中應用的越來越廣，對其控制的精度、穩(wěn)定性和工作效率等提出了更高的要求。</p><p>　　為了解決上述控制方面的問題，本課題對其液壓控制部分進行了設計。為了滿足控制的穩(wěn)定性，將液壓系統(tǒng)主要分為了兩個相對獨立的部分，分別控制

2、主泵送和S管的擺動，另外還對其攪拌回路進行了設計。這三個系統(tǒng)再加上其他輔助系統(tǒng)就形成了混凝土拖泵HBT40C-1008D的液壓系統(tǒng)。</p><p>　　機械部分主要對泵送系統(tǒng)進行設計分析，在我的設計中主要設計的是泵送油缸，在設計泵送油缸之前，先對整個液壓系統(tǒng)進行工況分析，編制負載圖，選定系統(tǒng)的工作壓力，然后根據(jù)使用要求選擇結構類型，按負載情況、運動要求、最大行程等確定其主要工作尺寸，進行強度、穩(wěn)定性和緩沖驗算，

3、最后再進行結構設計。</p><p>　　關鍵詞 混凝土拖泵；液壓系統(tǒng)；泵送系統(tǒng)；分配系統(tǒng)；攪拌系統(tǒng)</p><p><b>　　Abstract</b></p><p>　　Tow Concrete Pump has been used largely in urban construction, road and bridge const
