Adams/Solver
Input Arguments
x A double-precision variable that specifies the distance variable you want to
use to compute the force.
x' A double-precision variable that communicates to IMPACT the time
derivative of x.
x1 A double-precision variable that specifies the free length of x. If x is less
than x1, Adams/Solver calculates a positive value for the force. Otherwise,
the force value is zero. The value of x1 must be greater than zero.
k A positive, double-precision variable that specifies the stiffness of boundary
surface interaction.
e A positive, double-precision variable that specifies the exponent of the
force-deformation law. For a stiffening spring characteristic, e > 1.0. For a
softening spring characteristic, 0 < e < 1.0.
cmax A non-negative, double-precision variable that specifies the maximum
damping coefficient.
d A positive, double-precision variable that specifies the boundary penetration
at which Adams/Solver applies full damping. For a plot of damping
coefficient versus penetration, see IMPACT function (C++ or FORTRAN).
iord An integer variable that defines the order of the derivative IMPACT is to
return. The order is usually zero, but it can be one or two.
