Based on FEM Environmental Excitation to Mechanism Response Numerical Simulation Research

Study on mechanical vibration response produce by environment excitation, aimed on the large-scale high-speed quayside container cranes, affected by the environment load. For the huge cranes are vulnerable to wind turbulence produced by vibration, the impact load acted on the crane during the trolley traveling. By time domain random simulation of wind load, the wind-induced dynamic response analysis is done on the crane. The method of wind-induced dynamic response analysis of large structure is numerical simulation calculation. For the large high-speed gantry cranes under the environmental load of random response is key point, determine the bridge-type container crane under various conditions, the safety and reliability of the design is reasonable land bridge engineering requirement, high speed trolley motion has very important theoretical and practical significance. Research environment load caused by the random vibration response, dynamic response analysis method of wind-induced dynamic response analysis of large structure is random simulation of fluctuating wind load, namely the effect on the structure of stochastic wind field simulation. So, it’s important to calculate huge high-speed bridge-type container cranes under the environmental load of random response.
