Dynamic Analysis of Suspension-Type Monorail Long-Span Cable-Stayed Bridge in a Wind-Vehicle-Bridge System

Abstract The suspension-type monorail (STM) is a new type of rail transit, currently developing rapidly in China. Due to its short construction duration and high terrain adaptability, STM can save large land resources. In particular, by supplementing the traffic systems medium-sized cities, contribute green tourism projects. However, no systematic study devoted transit system China, there still lack relevant knowledge exploration, especially for special combination bridge. view real bridge, namely long-span (55 + 100 55)-m cable-stayed bridge this paper, applying wind-vehicle-bridge coupling vibration theory, ANSYS finite element method software, Universal Mechanism multi-body dynamics models are established vehicle, respectively. Furthermore, co-simulation adopted analyze vehicle-bridge vibrations ride comfort quality. According results, dynamic responses vehicle greatly affected variation wind speed, it necessary take measures decrease vibrations, thereby ensuring quality passengers.
