In developing a pantograph of a high speed train, reducing aerodynamic noise of the pantograph is one of the most important subjects. For reducing this noise, stability of aerodynamic lift force has a tendency to be spoiled and compensation method of lift force is required. Although there is some method for measuring the lift force, the existing methods have some restriction in actual use. For solving this restriction, the author developed a new method, by which the aerodynamic lift force can
