导出

摘要 成立了铰接式车辆原地转向阻力矩计较模子,推导了原地转向阻力矩计较公式,阐明白原地转向阻力矩的变革纪律和主要影响因素。与试验功效较量表白,理论阐明与仿真计较正确.对现有相关力学模子中存在的疑义举办了辨析,在转向进程中,转动阻力的偏向是否产生变革取决于车辆的布局参数,ope电竞游戏 ,存在着侧滑现象和轮胎侧向力并影响转向阻力矩。可用曲柄摇块机构举动学模子描写铰接式车辆原地转向,在成立力学模子时要相应地引进约束力. A computation model of in-situ steering resistance moment of articulated vehicles is established. The computation fbrmulas of in-situ steering resistance moment are derived. The change rules and main influencing factors of in-situ steering resistance moment are analyzed, and the correctness of the theoretical analysis and simulation computation is proved in comparison with the test results. Differentiation and analysis of doubtful points existing in the relative mechanical models are carried out. During in-situ steering, whether the direction of resistance to rolling change depends on the structure parameters of articulated vehicles, there exist tire side slippage and cornering force which exerts a certain influence on the computation of steering resistance moment. Kinematics model of in-situ steering of articulated vehicles can be described as a crank and rocker block mechanism, and the corresponding restraining forces must be introduced to establish the mechanical model.
