求助,那位高手帮帮忙
老说我纵向滑移率为1.0056 怎么改啊! 还有下面的问题!!请求指点!
WARNING: For TIRE JEEP.TIRE_1 the absolute value of the longitudinal slip ratio
has gone beyond its maximum allowable limit of 1.0.
Longitudinal slip ratio = 1.0056.
WARNING: A total of 20 warnings have been issued for trimming of slip
values that have exceeded their limits. ADAMS will no longer
issue warnings when it trims longitudinal slip ratios,
lateral slip ratios due to slip angle, lateral slip ratios
due to combined slip and camber angles, and comprehensive
slip values.
WARNING: The symbolic refactorization failed. The matrix is structurally
singular
at time = 5.62988E-04.
WARNING: The corrector has not converged after 6 attempts. No. of iterations = 10.
ERROR: The simulation stopped at time = 5.47095E-02 . ADAMS cannot solve
the equations of motion.
The greatest error in an equation is 7.83372E-05 in the
equation for GFORCE JEEP.TIRE_1.GFORCE_16912385 .
The greatest change in a variable is 1.32360E-16 in the
variable for PART JEEP.Right_UCA .
Try the following in this order:
1. Use the MAXIT argument on the EQUILIBRIUM, IC, KINEMATICS,
or INTEGRATOR command to increase the maximum number of
iterations.
2. Temporarily change the value of the PATTERN argument on the
EQUILIBRIUM, IC, KINEMATICS, or INTEGRATOR command to
PATTERN = T.
3. Temporarily increase the value of the ERROR argument on the
EQUILIBRIUM, IC, KINEMATICS, or INTEGRATOR command at
time = 5.47095E-02 .
4. If one or more forces change rapidly or sharply near
time = 5.47095E-02, modify the force or forces.
ERROR: Simulation failure detected |
