蛇行运动的试验研究需要高速机车、车辆以及安全可靠的线路的配合才能进行。而模型定置台试验具有制造费用省、改变方案迅速省时、方便地重演机械振动物理现象等基本优点。它除了模拟垂直向平面振动外,还能模拟试验横向水平平面的蛇行运动,为研究机、客、货车高速蛇行运动问题提供有力的辅助工具。因而,成为当前国内外十分 Experimental research on hunting behavior requires the cooperation of high-speed locomotives, vehicles and safe and reliable lines. However, the model set bench test has the advantages of low manufacturing cost, quick and time-saving plan change, easy replay of physical phenomena of mechanical vibration, and the like. In addition to simulating the vibration perpendicular to the plane, it can also simulate the meandering horizontal motion of the horizontal plane, providing a powerful aided tool for the research on the high-speed hunting motion of passenger cars and trucks. Therefore, becoming the current domestic and foreign very
