如题，错误信息如下：

Static equilibrium analysis has not been successful.
  The maximum number of iterations 75, has been reached.
  For the last attempted iteration:
  The equation with the largest error was model.body.ges_frame Comp = 7 Error = 363317.052546
  The variable receiving the largest increment was model.testrig.jfs_steering_rack_force.force Comp = 0 Delta = 38881057.958785.

有大神能够指点下吗
