Abstract

Ji, Q. and Kun, L., 2018. Numerical simulation solutions for wind-induced vibration of ship rearview mirrors caused by airflow noise in shallow seas. In: Ashraf, M.A. and Chowdhury, A.J.K. (eds.), Coastal Ecosystem Responses to Human and Climatic Changes throughout Asia.The fluid–solid coupling method was used for numerical simulation of the problem of wind-induced vibration of an exterior rearview mirror caused by airflow. The finite element model was established. The fluid–solid coupling method was used to consider the process of interaction between fluid and solid. The dynamic characteristics of the rearview mirror under the coupling condition at different speeds were calculated. Experimental results show that when the vortex shedding frequency is close to the natural frequency of the rearview mirror structure, a strong vibration in the rearview mirror can result. This numerical simulation can simulate the actual situation.
