关于带摆动桥的三点支承轮式机械行驶状态横向稳定性及其计算方法已经进行过比较深入的研究。这类机械中,有些要求经常固定(不行驶)作业。作业时,常受到各种外力的作用。例如,图1所示是一种锥探机,用于河道或水库堤坝的维护。该机靠钻头挤入土层探测大坝有无隐患。斜向打孔时,地面对其作用一斜向反力(图1)。机器能否正常工作,与横向稳定性直接有关。 The lateral stability of the three-point supported wheel-type mechanical traveling state with a swing bridge and its calculation method have been studied in depth. Some of these machines require frequent (non-traveling) operations. When working, it is often subjected to various external forces. For example, Figure 1 shows a cone probe machine for the maintenance of river or reservoir dams. The machine drilled into the soil by drilling to detect hidden dangers. When the hole is drilled diagonally, the ground exerts an oblique reaction force on it (Fig. 1). Whether the machine can work normally is directly related to lateral stability.
