我仿真的时候为什么总是出现如下问题啊？？？到底是怎么回事啊？请高手指教啊！
WARNING: The symbolic refactorization failed. The matrix is structurally singular
at time = 0.29140.
WARNING: The corrector has not converged after 5 attempts. No. of iterations = 10.
WARNING: The corrector has not converged after 4 attempts. No. of iterations = 10.
WARNING: The corrector has not converged after 2 attempts. No. of iterations = 10.
WARNING: The corrector has not converged after 2 attempts. No. of iterations = 10.
WARNING: The corrector has not converged after 2 attempts. No. of iterations = 20.
ERROR: The simulation stopped at time = 0.29140 . ADAMS cannot solve
the equations of motion.
The greatest error in an equation is 5.67443E-03 in the
equation for GFORCE JEEP.Right_front_tire.force .
The greatest change in a variable is 6.69906E-15 in the
variable for PART JEEP.Center_link .
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 = 0.29140 .
4. If one or more forces change rapidly or sharply near
time = 0.29140, modify the force or forces.
ERROR: Simulation failure detected |
