摘要
通过铰接车辆转向时的受力分析,推导出了铰接式铲运机车体转向时的动态数学模型,可用于研究整机在加速、制动和转向时的动态特性。同时也建立了该种铲运机转向时横向稳定动态数学模型,可用于研究整机转向时的横向稳定动态特性。这两种数学模型所研究的动态特性均与铲运机的结构参数有关,因而可为铲运机的结构设计和参数确定提供理论依据。
A dynamic hmathematic model for articulated LHD body steering is established by means of foree analysis during articulated vehicle steering and it is useful for investigation into dynamic characteristics during acceleretion, braking and steering oiathe whole machine, A dynamic methematic model for lateral stability during articulated LHD steering is also established, which is useful for study on lateral stability dynamic characteristics during the whole machine streeing. The dynamic features obtained by the two mathematic models are related to structure parameters of LHD, thus providing a theoretical basis for struotural design and parameters determinathon.
