x The distance variable you want to use to compute the force. For example, if you want to use the x displacement of Marker 0201 with respect to 0301, then x is DX(0201,0301,0301).
The time derivative of x to BISTOP. For example, if x is DX(0201,0301,301) then is VX(0201,0301,0301,0301).
x1 The lower bound of x. If x is less than x1 ADAMS/Solver (C++) calculates a positive value for the force. The value of x1 must be less than the value of x2.
x2 The upper bound of x. If x is greater than x2 ADAMS/Solver (C++) calculates a negative value for the force. The value of x2 must be greater than the value of x1.
k A non-negative value that specifies the stiffness of the boundary surface interaction.
e A positive value that specifies the exponent of the force deformation characteristic. For a stiffening spring characteristic, e > 1.0. For a softening spring characteristic, 0 < e < 1.0.
cmax A non-negative variable that specifies the maximum damping coefficient.
d A positive real variable that specifies the penetration at which the full damping coefficient is applied.作者: yihuang200614 时间: 2007-3-4 10:20
d指的是两个物体的穿透距离作者: duanming306 时间: 2007-5-10 15:36
d 指的是阻尼完全起作用的穿透距离,就是指当距离小于d的时候阻尼最大
