不知道，我加的接触和约束对不对，计算结果有警告
活塞销的整个面和活塞销孔采用小摩擦接触，连杆和活塞销之间采用bonded接触。连杆截面固定约束。
警告：
one or more bodies may be under constrained and experiencing rigid body motion .weak springs have been added to attain a solution .(这个可以理解，采用无摩擦接触会加weak springs求解)
contact status has experienced an abrupt change results carefully for possible contact separation.
an iteration solver was used for this modle .however ,adirect solver may enhance performance .consider specifying the use of adirect solver.refer to troubleshooting in the help system for more details.
