间隙补偿及液体垫片参数对层合板单层与层间应力的影响
Effect of Gap Compensation and Parameters of Liquid Shim on Composite Laminates Internal Stress and Interlaminar Stress
摘要
Abstract
In general,the liquid shim is used to compensate the small gaps between the composite components in the aircraft assembly.The single bolt connection of composite laminates as the object,one experiment were designed:the measurement of the strain of laminated plate,and two cases are considered in the process:using a fiquid shim to compensate for the gap and without it;The finite element model was built and validated by using ABAQUS software.The calculation results are in a good agreement with the experimental.Under different liquid shim compensation paraneters,the change in the stress of laminated plate,including laminates internal stress and interlaminar stress are studied based on the present model.The results show that:with the increasing of gap,the liquid shim is rnore significant to improve the stress distribution,reduce the stress amplitude,and enhance the ability to resist delamination;the three generations liquid shim have very little differences on laminates internal stress and interlaminar stress;laminates internal stress will be significantly improved if a substantial increase in the elastic modulus of the shim.关键词
