Abstract:
Aiming at the adhesive structure of EMU information window, considering the influence of environment and load on the life of adhesive structure, a life prediction method combining the accelerated aging and natural aging was proposed. The influence factors of adhesive structure were analyzed, and the temperature-dynamic load coupling cycle spectrum of accelerated aging was established. The aluminum alloy butt joints were made and the accelerated aging tests with 0, 10, 20 and 30 cycles were carried out, respectively. The residual strength and failure mode of joint were tested regularly, and the change rules of adhesive residual strength under the load cycles were obtained. The real vehicle adhesive strips with different driving mileages under natural aging were extracted, and the residual strength test was performed to obtain the change rule of adhesive residual strength with driving mileage. The polynomial function was used to fit the function relations of load cycles and driving mileage with the residual strength attenuation rate of adhesive. The functional relation between the load cycle and driving mileage was established. Analysis result shows that compared with the initial strength of adhesive joint, the residual strength of adhesive joint decreases by 11.6%, 15.9%, and 20.7% after 10, 20, and 30 temperature cycles, respectively, while the strength of adhesive joint decreases by 14.1%, 18.9% and 24.8% after the coupling cycle of temperature and dynamic load, respectively, which shows that the dynamic load intensifies the decline of joint strength, and presents the decline trend fast first and then slow. After the coupling test of temperature and dynamic load, the failure mode and mechanism of joint section change obviously. Initially, the joint adhesive layer suffers aging failure, and then with the increase of load cycles, the main failure mechanism of joint changes from aging failure to fatigue failure. It is found that the attenuation rate changing trends of adhesive failure strength under accelerated aging and natural aging are basically the same. The functional relationship between load cycle and driving mileage can accurately predict the life of adhesive structure, and the maximum safe mileage of high-speed train is 8.34×106 km. 1 tab, 18 figs, 30 refs.
