【Abstract】 According to the working characteristic of floating hydraulic-operated automatic gate, the model test of loss head is well analyzed and studied. Using the new method, the working characteristic of hydraulic-operated automatic gate at different design parameter is finely simulated. The weight of gate is changed during the model test to study the relationship between moment of buoyed weight of gate and loss head. Based on the model test, the relationship between loss head and other variables is analyzed, by using the mathematical physics method and the equation of criterion. And a empirical formula is also proposed.更多还原
