In the aircraft hydraulic system, hydraulic reservoir is the very essential components, which can supply hydraulic oil to all kinds of hydraulic facilities such as flight control actuators, brake system, and so on. Normally, There are two kinds of hydraulic reservoir. One is pressurized reservoir and the other is non-pressurized. On the other hand, according to SAE AS5586 which is aerospace engineering specification, the types of reservoirs should be divided into 5 kinds of types from type A to type E. Among them, in case of type D(non-separated, gas pressurized) and type E(non-separated, non-pressurized), the hydraulic oil movement in them could not be limited so that the oil is fluctuated according to flight condition or gravity. Sometimes, the 0il moves against gravity. As the result of successive and excessive sloshing, the wall of reservoir could be shocked or damaged . From time to time, the fracture of reservoir could be generated. Because of the safety reason, the key study of this paper is to avoid the fracture problem. Therefore, in this paper, it is analized the natural frequency of the fluid by analyzing the sloshing phenomenon of the internal fluid and by analyzing the natural frequency of the reservoir, it checks the mutual resonance to design a safe structure that does not cause excessive sloshing. It has its aim.
