| 摘 要： | 针对直升机系留系统,基于虚功原理推导了机体刚体位移的方程组。应用Newton-Raphson迭代法可求解机体在外载作用下的刚体位移,从而求得系留索和系留接头的载荷。与有限元方法相比,此方法便于处理索具的预紧力和起落架的初始压缩,计算精度也符合工程应用的要求。

| Abstract: | A equations set of rigid displacement of the helicopter body was derived based on virtual work principle.Newton-Raphson iterative method was used to solve rigid displacement,then the mooring load of chains and joints was computed.Comparing with finite element method,the method is more convenient for dealing with pretightening force and initial compression,and the result is available for engineering application. |
