摘要
对严格Janbu法公式重新进行了推导,在深入分析的基础上对其求解流程进行改进,变求导为积分,避开了求导误差。通过对算例的分析,指出严格Janbu法不收敛的根本原因是其推力线高度的假设不合理。
On the basis of the fundamental principle of rigorous Janbu method,formulas are re-derived.Through modifying the flow of the method, the differential operation can be transformed to integral operation so as to avoid the derivative's error. The example analysis indicates that the inherent cause of non-convergence is the assumption of rigorous Janbu method; the assumption about the line of thrust is unreasonable.
