摘　　要：一般的仿真物理建模是基于能量守恒,质量守恒,动量守恒等三大守恒定理建立的,而现在介绍的流体力学中的伯努利定理,就是由机械能守恒推导而来的,所以它仅适用于粘度可以忽略、不可被压缩的理想流体,而水作为常见的流体,其属性是可以理解为粘度可以忽略、不可被压缩的理想流体的。首先基于伯努利定理来建立水电站引水系统流量-压力的数学模型,再采用计算机语言对所建立的数学模型进行编程,以此实现对象系统的实时动态的仿真过程。The general simulation physics modeling is based on three conservation theorems such as energy conservation, mass conservation and momentum conservation, while the Bernoulli-theorem in fluid mechanics introduced in this paper is derived from mechanical energy conservation, so it is only applicable to the ideal fluid with viscosity ignored and incompressible, and water, as a common fluid, its properties can be understood as viscosity negligible and incompressible ideal fluid. Therefore, the mathematical model of flow-pressure was established based on the Bernoulli-theorem, and the established mathematical model was programmed by computer language to realize the real-time dynamic simulation process of the object system.
