The force increasing principle and mathematical model of a brace force increasing mechanism are analyzed in detail, and the changing laws of the force increasing ratio are obtained by using the method of numerical simulation. The results show that the brace force increasing mechanism has a great force increasing ratio. The relations between the force increasing ratio and the distances from the gemel D to link rod 2 and 4 are exponential relation of normal distribution and inverse ratio relation of hyperbola respectively.
