摘要
分析了具有摩擦的二维相对运动的边界条件对系统运动状态的影响。结果表明:系统的运动情况、边界条件和各参量之间有较强的依靠关系。在不同的初始条件下,给出了物体B的速度ν随着时间变化的数值分析,并给出了-νt图。
The motion state of a mechanical system which was affected by boundary conditions of two-dimensional relative motion with friction was analyzed.The result indicates that there are strong qualitative dependence relations among behavior of the system,boundary conditions and parameters.The velocity of object B with time change under different initial conditions is numerically analyzed,and a series of ν-t figures was given.
