第三讲相似与模型实验模型实验是用不同于实物的简便方法代替实物系统进行的实验,研究有关现象与机理和主要因素的关系推定实物系统中产生的现象的方法。例如研究汽车冲撞时乘车人受到的伤害程度,明显的不能用人和实物进行试验,只能用人的模型和实物进行试验。在设计这种模型试验时应用因次分析和类似的某些相似的模型法则。
Lecture 3: Similarity and Model Experiments Model experiments are experiments performed in place of the physical system by a simple method that is different from the physical object, and studies the relationship between the phenomena and the mechanism and the main factors to infer the phenomena that occur in the physical system. For example, studying the degree of injury suffered by motorists in the event of a car collision obviously can not be tested with human and material objects, and can only be tested with human models and real objects. Some similar model laws of the order of analysis and similar are applied when designing this model test.
