题目所给飞机机翼受的是平均载荷,所以要计算每一站点上的剪力,弯矩和扭矩,就要先算出其所在平面的面积和其合力作用线到某一座标轴的距离,及集中载荷作用线到中心线的距离。带载荷等于面积乘以平均载荷,某一站点剪力等于此站点之前所有带载荷之和。弯矩等于剪力乘以合力作用线到其对应坐标轴的距离。扭矩等于剪力乘以集中载荷作用线到中心线的距离。所得结果与笔算结果基本吻合。程序具有一定的通用性。
Subject to the aircraft wing by the average load is, so each site to calculate shear, moment and torque, we must first calculate its area in the plane and its force action line to the distance of a coordinate axis , and concentrated load line to the centerline distance. With a load equal to area multiplied by the average load, a shear force equal to this site before the site with loads of and all. Multiplied by the effect of shear force bending moment is equal to the corresponding axis line to the distance. Torque multiplied by the concentrated load is equal to the shear line to the centerline distance. The results results are consistent with written calculation. Program has some versatility.
