现有分支轴系的传递矩阵法不仅需针对具体传递结构编制程序，而且它的剩余扭矩存在奇点。作者指出传动系的拓扑结构为树型。利用这一特点，构造了一种递归格式，只须提供描述传动系的数据，无须多次编程和调试。通过对传递过程的修正，消除了余量函数的奇点。算例结果表明所提出的算法是稳定和高效的。 The transfer matrix method of the existing branch shaft system not only needs to program the specific transfer structure, but also has a singular point of its remaining torque. The author points out that the topology of the powertrain is a tree. Using this feature, a recursive format is constructed that requires only the data that describes the driveline, eliminating the need to program and debug multiple times. By correcting the transfer process, the singularity of the residual function is eliminated. The results show that the proposed algorithm is stable and efficient.
