临界位置时构架的受力分析

Analysis of Forces Sustained on Frame at Critical Position

对转向架处于中间位置和弦形位置间的临界位置时构架的受力进行了细致分析,计算了209PK型转向架构架在临界位置和中间位置的受力大小,计算结果表明。

Forces sustained on frame at critical position between chordal position and midst position are analyzed carefully. The forces on 209PK bogie frame at critical position and midst position are calculated separately. The results show that forces on frame at critical position are different largely from those at midst position.
