求帮助，adams振动模块仿真时出错

crude25

在用振动模块仿真时出现的错误请大神指点
WARNING: While processing expression "FX(4)" for model_1.Output_Channel_1.output_channel_variable
the use of an FX, FY, FZ, FM, TX, TY, TZ or TM measure
using only a single marker argument was detected.  Whereas
in the F77 Solver this measures the sum of *action-only*
forces acting at this marker, in the C++ Solver the total
sum of *all* forces acting on the marker is measured.  Please
adjust your model accordingly
WARNING: QR: The eigen solution produced one or more defective eigen values.
    For these eigen values generalized eigen vectors will be used in the solution.
    This generally indicates a problem with the model (zero stiffness, free body, invalid constraint).
