    摘要:

    針對步行式挖掘機(jī)坡度橫向行走時的穩(wěn)定性問題，建立了包含底盤機(jī)構(gòu)和作業(yè)裝置多自由度系統(tǒng)的步行式挖掘機(jī)靜力學(xué)模型,，并考慮了作業(yè)裝置回轉(zhuǎn)運(yùn)動時附加慣性力矩,，構(gòu)造了步行式挖掘機(jī)橫向行走時穩(wěn)定性分析的多目標(biāo)優(yōu)化模型。利用效用函數(shù)法對多目標(biāo)優(yōu)化模型進(jìn)行求解,，對橫向行走的最大坡度,、底盤和作業(yè)裝置的狀態(tài)參數(shù)進(jìn)行了優(yōu)化分析。結(jié)果表明,，該方法簡單,、可靠，為確定步行式挖掘機(jī)坡度橫向行走時的步行機(jī)構(gòu)狀態(tài)參數(shù)和安全控制提供了理論依據(jù),。

    Abstract:

    For the purpose of analyzing the stability of walking mobile excavator, which moving cross direction on the sloping ground, a static model including multi-degree system for working mechanism and chassis mechanism was described, and the additional inertia moment of working device during its rotating was also considered. A mathematical model of multi-objective optimization for the stability of walking mobile excavator was constructed. The utility function method was employed to solve the optimal model. The maximum degree of slope and state parameters of working mechanism and the chassis were optimized. The results showed that the proposed method has its merits, such as simple and reliable, and it could provide theoretical basis for confirming the cross direction moving parameters of the walking mobile excavators and safety controlling.
