CFRP组合式桥墩防撞装置的设计与优化研究
Design and Optimization Study of CFRP Combined Pier Anti-Collision Device
摘要
Abstract
In order to effectively protect ships and piers in the case of accidental collision,a CFRP honeycomb type anti-collision device with higher crashworthiness,better crashworthiness and better service life is designed in this paper.Taking large-tonnage cargo ships and common bridge piers in the middle reaches of the Yangtze River as the research objects,the energy conversion response,impact force response and impact depth response of the collision are studied by considering the collision conditions under the ship and the bare pier and under the ship and the collision avoidance devices.On this basis,the response surface method,the variance analysis method and the efficacy coefficient method are further adopted to take the shell thickness of the collision avoidance device and the thickness of the internal steel structure as the design parameters.The multi-objective optimization design of the CFRP composite anti-collision device is carried out by selecting the ship impact force,the total internal energy absorbed by the anti-collision device,the total mass and the inner diameter of the honeycomb steel structure as the optimization objectives.The results show that the reduction rate of impact force reaches 82.7%and the overall mass is greatly reduced.Meanwhile,the maximum deformation is within a reasonable range,and the collision resistance is optimized.关键词
