Abstract: This study is based on the shipboard Mark 7 Mod 1 arresting system and extends it to Mark 7 Mod 3 arresting system with the help of its experiential formula.First,the stroke of K-5 cam is extended to 4.65 m by redesigning the cam configuration to optimize the arresting system,so that the capacity of the arresting system is increased.Second,the mass of the main pressure carriage and the elasticity of the cable should be considered in the arresting system,so the kinetic simulation consists of the inertia of the main pressure carriage,the damper sheaves and the aircraft.Third,the arresting system model is extended with the addition of damper sheaves,so a more accurate and complete model is established.Finally,in light of the cam configuration and the discharge coefficient variation,an accurate hydraulic model is proposed to analyze the relationship between the states of the aircraft and the arresting system parameters.

Key words: hydraulic fluid, carrier-based arresting system, kinetic simulation, weight selector, contour of the cam
