在Hydraulics模块仿真中遇到的问题

luzhifang

需要模拟液压缸的动作，我先建一个简单的模型，在活塞杆和液压缸上设定I-Maarker和J-Marker，再画出液压原理图进行仿真，结果不能运行仿真，出现错误：
WARNING:    The corrector has not converged after 6 attempts. No. of iterations = 10.
ERROR:      The system matrix has a zero pivot for column 15, which is associated
   with TRANS JOINT/1 SX Forc.  Consequently, the matrix is numerically singular.
ERROR:   Abnormal termination encountered in ADAMS/Solver.
苦于不知道是哪错了，十分郁闷，请高手指点！谢谢！
