According to the domestic and foreign research results of the trash rack design of hydropower station,design load and its dynamic analy-sis during the trash rack design was discussed. The dynamic characteristics is relevant to flow pattern,shape of hydraulic structures of water inlet, nature and quantity of floating objects,flow velocity across trash track,discharge across trash track and other factors. The trash rack has complex dynamic characteristics under various working conditions. Therefore,it was essential to analyze the dynamic characteristics and anti-vibration design method of trash rack from the view of fluid mechanics and structural dynamics.
