    模型有哪些分类呢

        模型可以取各种不同的形式,不存在统一的分类原则。按照模型的表现形式可以分为物理模型、数学模型、结构模型和仿真模型。
    Models can take different forms, and there is no uniform classification principle. According to the form of the model, it can be divided into physical model, mathematical model, structural model and simulation model.
    实物模型,根据相似性理论制造的按原系统比例缩小的实物,例如风洞实验中的飞机模型,水力系统实验模型,建筑模型,船舶模型等。

    The physical model, based on the similarity theory, reduces the original system ratio , such as the aircraft model in the wind tunnel experiment, the hydraulic system experimental model, the building model, the ship model and so on.

    类比模型,在不同的物理学领域的系统中各自的变量有时服从相同的规律,根据这个共同规律可以制出物理意义完全不同的比拟和类推的模型。例如在一定条件下由节流阀和气容构成的气动系统的压力响应与一个由电阻和电容所构成的电路的输出电压特性具有相似的规律,因此可以用比较容易进行实验的电路来模拟气动系统。
    The analogical model, in the systems of different physics fields, sometimes obeys the same rules, and can make the analogy and analogy model of physical meaning completely different according to the common law. For example, under certain conditions, the pressure response of a pneumatic system consisting of a throttle valve and a gas capacity is similar to the output voltage characteristic of a circuit composed of resistance and capacitance. Therefore, an experimental circuit can be used to simulate the pneumatic system.
    工业模型,俗称手板、首板模型和快速成型,主要制作方法有CNC加工、激光快速成型和硅胶模小批量生产。工业模型广泛应用于工业新产品设计研发阶段,在短的时间内加工出和设计一致的实物模型。设计师进行产品外观确认和功能测试等,从而完善设计方案 ,达到降低开发成本,缩短开发周期,迅速获得客户认可的目的。

    Industrial models, commonly known as hand boards, head board models and rapid prototyping, are mainly made by CNC processing, laser rapid prototyping and small batch production of silica gel mold. Industrial models are widely used in the design and development stage of industrial new products. In the shortest time, a physical model is designed and designed. The designer carries out the product appearance confirmation and the function test, so as to perfect the design scheme, reduce the development cost, shorten the development cycle, and quickly obtain the purpose of customer recognition.
