摘要:

針對(duì)四履帶車(chē)輛特點(diǎn)，建立了考慮履帶寬度以及滑轉(zhuǎn)、滑移的四履帶車(chē)輛穩(wěn)態(tài)轉(zhuǎn)向數(shù)學(xué)模型，并對(duì)模型進(jìn)行了數(shù)值求解，分析了各因素對(duì)其穩(wěn)態(tài)轉(zhuǎn)向性能的影響。基于多剛體動(dòng)力學(xué)軟件RecurDyn對(duì)某四履帶車(chē)輛進(jìn)行了虛擬樣機(jī)轉(zhuǎn)向仿真試驗(yàn)，仿真結(jié)果與理論計(jì)算吻合較好，證明模型具有較高的可靠性。

Abstract:

Based on the characteristics of four-tracked vehicles, the mathematical model of steady steering on firm ground was established, considering the crawler width and skidsteering. The influences of the factors on the steering performance were analyzed. The virtual prototype of a fourtracked vehicle was built based on the multibody dynamics software RecurDyn and the steering tests were completed. The virtual prototype simulation results accorded well with the numerical results, which verified the correction of the theoretical model.
