摘要
直升机的飞行过程是一个复杂机械集合体在空气动力作用下进行复杂运动的过程,文中采用二阶升力线方法,进行非线性空气动力学动态/静态分析,通过弹性/刚性梁单元+弹簧连接件的处理方法和多体动力学方法,计算旋翼空气动力学和结构动力学的耦合影响。
The helicopter flight course is that a complex mechanical aggregation makes the intricate athletic process under the air motivity.Applying two order lift line method,doing the nonlinear aerodynamic dynamic/static analysis,by the disposal method of the flexible/rigid element cell add spring joint part and multi-body dynamical method,the coupling effect of the rotor aerodynamic and structure dynamic is calculated.
