Buffer Structure

Analyzed and studied the hydro-pneumatic buffer structure of railway vehicle, designed a new type of hydro-pneumatic buffer and established the detailed dynamics model. Calculated the static characteristic curve of hydro-pneumatic buffer with different compression rate and dynamic characteristic curve with different impact speed through the numerical simulation method. The simulation results shows that the biggest impedance force is 1836.3KN and buffer capacity reach 221.89KJ when impact velocity of the new hydro-pneumatic buffer is 5m/s.New hydro-pneumatic buffer can improve the speed of manipulating vehicle, reduce the longitudinal impact and vibration in the train and adapt to the needs of the trains.

As a new type of vertical-wall breakwater built in soft ground a breakwater, composed of a single row of large steel pipes with diameters of some 1.5 to 3.0 meters driven into a sea bottom, has been proposed for the water areas where are not directly exposed to a great ocean. Experiments for the fundamental study were conducted in the medium wave channel of the hydraulic laboratory in Osaka City University, and model experiments were performed for practical design of the steel pipe breakwater planned to build in the Port of Osaka at a 1/10 scale in the large wave tank in the Field Hydraulic Laboratory.
