Ratio control of cvt is the key for engine running according to ideal curve , and controlling thrust of driving and driven pulley reasonably can improve efficiency and extend life - span of metal belt , and it is coupling relation between control of ratio and thrust 無(wú)級(jí)變速傳動(dòng)系統(tǒng)的速比控制是實(shí)現(xiàn)發(fā)動(dòng)機(jī)按理想工作線運(yùn)行的關(guān)鍵,合理控制主、從動(dòng)帶輪的夾緊力能提高傳動(dòng)效率和金屬帶的壽命,而夾緊力和速比控制存在耦合效應(yīng)。
In order to consider the reduction of the thrust at springer , three optimization design methods , i . e . method by firstly controlling stress of section based on sensitivity analysis , method by firstly controlling thrust at springer based on sensitivity analysis , and design method based on optimum theory , are suggested 同時(shí),為在設(shè)計(jì)時(shí)考慮減小拱腳不平衡推力這一因素,提出了基于敏感性分析的首控截面應(yīng)力雙控設(shè)計(jì)法、首控拱腳凈推力雙控設(shè)計(jì)法以及直接利用優(yōu)化理論進(jìn)行設(shè)計(jì)等3種合理優(yōu)化設(shè)計(jì)方法。
