模拟重力场 meaning in English

simulated gravity field

However , it is too expensive in investment , complex in experimental techniques , difficult and dangerous in performance . in this paper to overcome these drawbacks , the similarity relations together with a new method and its principle of experiment have been developed based on the model theory of structural similarity . according to this principle , the total stress ; an be obtained as a sum of the stresses due to weight and external loading , which based on only one model experiment without any gravitational loading
最后，针对外载与自重共同作用下，传统光弹性分析法中采用离心力场模拟重力场获得自重应力的试验投资耗费大、技术复杂且难度大和不安全等严重缺点，按照结构相似的模型理论，本文提出模型外载与自重并存变动外载的光弹性分析法，导出处理这个问题具体的相似律和试验原理及方法，进行了典型实验验证，指出仅用外载作用的模型试验，即不用离心力场模拟重力场的模拟试验，就可以获得上述两种载荷共同作用下的应力分析结果。
