本文考虑了影响原木运材汽车列车行驶方向稳定性的主要因素,将汽列的每节挂车简化为三个自由度(侧向,横摆和侧倾运动。)的二质量(簧上,簧下质量。)的动力学计算模型。确定汽列稳定行驶的极限速度的数学表达式。分析了影响汽列行驶方向稳定的主要因素:重心的位置与高度;挂车的轴距,载量;轮胎的侧偏刚度、气压。从动态稳定性角度确定挂车的合理结构及尺寸。
In this paper, the main factors affecting the stability of the log car traveling direction are taken into account, and the steam quality of each trailer is reduced to three degrees of freedom (lateral, yaw and roll movements) Lower mass.) The kinetic calculation model. The mathematical expression that determines the limit speed of a steady steam column. The main factors influencing the stability of steaming are analyzed: the position and height of the center of gravity; the wheelbase and the load of the trailer; the stiffness and pressure of the tire. From the perspective of dynamic stability to determine the reasonable structure and size of the trailer.
