摘要: 为获取发动机碳纤维复合材料(CFRP)/三元乙丙橡胶(EPDM)粘接界面性能参数,本文基于DCB试样和双线性内聚力模型获取了界面断裂能和试验曲线,结合利用ABAQUS搭建的DCB仿真平台,输出仿真曲线。根据仿真曲线和试验曲线的差异,建立仿真曲线和测试曲线的重合度公式,作为优化的目标函数,采用响应面等优化算法求解函数最小值及其对应的变量值,获得界面性能参数的精确值。本文采用性能测试-数值仿真-优化计算相结合的方法获取了CFRP/EPDM粘接界面性能参数,并基于测试与仿真对参数进行验证,结果吻合良好,可为发动机在服役工程中出现的界面失效破坏提供判据。

Abstract: In order to obtain the interfacial properties parameters of carbon fiber reinforced plastic(CFRP)/ethylene propylene diene monomer (EPDM) adhesive for engines, this paper obtained the interfacial fracture energy and experimental curves based on DCB specimens and bilinear cohesive force models. Combined with the DCB simulation platform built using ABAQUS, the simulation curves were output. Based on the difference between the simulation curve and the experimental curve, establish a formula for the overlap between the simulation curve and the test curve as the optimization objective function. Use optimization algorithms such as response surface to solve for the minimum value of the function and its corresponding variable values, and obtain the accurate values of the interface properties parameters. This article uses a combination of properties testing, numerical simulation, and optimization calculation to obtain the properties parameters of the CFRP/EPDM adhesive interface, and verifies the parameters based on testing and simulation. The results are in good agreement, providing a criterion for interface failure and failure of engines in service engineering.
