飞机机体疲劳定寿载荷计算

飞机机体的疲劳载荷对确定飞机的使用寿命有着非常重要的作用。给出一种计算飞机疲劳载荷的方法，并对某型飞机疲劳载荷进行了计算，收到较好效果。该方法是通过对数值模拟结果或测压实验结果进行积分获取飞机机体各部件的载荷分布和载荷作用点，并根据飞机的运动平衡方程进行载荷平衡修正以获得最终用于设计的疲劳载荷。

Research on Load Calculation of Determining Fatigue Life of an Aircraft

The fatigue load of an aircraft plays a very important role in determining the service life of the aircraft. A method of calculating aircraft fatigue load is given in this paper, which is applied to a certain type of aircraft and effective in practice. The fatigue load finally used for designing is achieved first by integrating the numerical value simulation results or the pressure measuring test results to obtain the load distribution over and the acting point of load on each part of an aircraft body, and then performing load balance correction according to the equation of motion balance of aircraft.
