This paper presents to investigate dynamic stiffness of inspection robot with various frame structures through flexible multi body dynamic simulation. Transmission lines which simulated in finite element model are used to validate to experimental results. Natural frequency analysis of robot frame is conducted to compare with sub-span ocillation frequency. Multi body dynamic simulation model that is similar to the actual sub-span ocillation test environment is developed by using transmission lines and robot frame models. New 5 types robot frames with reduced the number of carbon pipes are proposed. Natural frequency analysis and multi body dynamic simulation of 5 types robot frame are conducted. The final robot frame model is confirmed that 29% of weight was reduced.
