    摘要:

    闡述了一種擺動式復(fù)合轉(zhuǎn)向機(jī)構(gòu)，利用Denavit-Hatenberg齊次變換矩陣建立了該轉(zhuǎn)向機(jī)構(gòu)的運(yùn)動學(xué)模型,，提出了確定復(fù)合式轉(zhuǎn)向機(jī)構(gòu)關(guān)鍵鉸點(diǎn)位置的多目標(biāo)優(yōu)化設(shè)計(jì)方法,，結(jié)合工程實(shí)例,，對轉(zhuǎn)向機(jī)構(gòu)進(jìn)行了優(yōu)化設(shè)計(jì),，用ADAMS軟件對計(jì)算結(jié)果進(jìn)行了驗(yàn)證,，對轉(zhuǎn)向機(jī)構(gòu)的轉(zhuǎn)向油缸驅(qū)動的非對稱特性,，轉(zhuǎn)向機(jī)構(gòu)的平順性,、側(cè)滑特性和對稱特性進(jìn)行了分析。結(jié)果表明,，提出的優(yōu)化計(jì)算方法具有簡單,、可靠的特點(diǎn)，該轉(zhuǎn)向機(jī)構(gòu)具有轉(zhuǎn)彎半徑小,、側(cè)滑小和易控制等特點(diǎn),。

    Abstract:

    An oscillating combined steering mechanism was introduced. With Denavit-Hatenberg homogeneous transformed matrix, the kinematics model of the steering mechanism was constructed. The multi-objective optimization method for designing the location of key hinge was proposed. The engineering illustration of steering mechanism was calculated, and the result was proved by the ADAMS software. Some characteristics of steering mechanism, such as the asymmetry of steering drive oil cylinder control, steering smoothness, skidding behavior, and symmetrical distribution were analyzed. The proposed method was reliable and simple, and had important practical value for engineering applications. The steering mechanism had some merits, such as small turn radius, little side slide, easily controllable, it will have wide applied range in engineering vehicle.
