矫形力与垫片补偿对复合材料装配结构变形及螺栓夹紧力的影响
Effect of Orthopedic Forces and Shim Compensation on Deformation of Composite Assembly Structure and Bolt Clamping Force
摘要
Abstract
The assembly clearance caused by low accuracy of aircraft composite component formation can be reduced or even eliminated by applying a straightening force,and a larger gap can be compensated by applying a shim.Composite wall plate was taken as reserch subject to observe its deformation during the process of straightening,bolting and withdrawal of straightening force as well as the change of bolt clamping force after the withdrawal of straightening force by the test method.The results show that the deformation of the wall plate increases with the increase of the orthopedic force,the corresponding shim compensation size decreases,and when orthopedic forces reach a certain degree,the deformation tends to stabilize.After the withdrawal of the orthopedic force,the rebound of the wall plate assumes approximate linear relationship with the value of the orthopedic force,and when orthopedic forces reach 150 N,the maximum rebound is 0.117 mm,accounting for 7.83%of the assembly gap.After the withdrawal of the orthopedic force,the bolt clamping force in each area has a tendency to increase,among which,the region where the gap between the wall plate and the skeleton exists,the clamping force grows relatively obviously,and when the maximum change in clamping force is 50 N,the growth rate reaches around 1%.关键词
