相似模拟试验是以相似理论、因次分析作为依据的实验研究方法,广泛应用于采矿、地质、水利、铁道等部门。随着不同门类研究的深入,各式各样的相似模拟支架应运而生,然而传统模拟支架也有其缺点,主要表现为顶部铺料难下手、不易操作、压实难等情况,导致试验时模型分层不平整,蓬松掉渣现象,增加了试验误差。因此,设计了一种可调节升降高度的相似模拟支架,解决了工作中铺料难、压实难的问题,节约了作业时间。 Similar simulation test is a kind of experimental research method based on similarity theory and secondary analysis, which is widely used in mining, geology, water conservancy, railway and other departments. With the development of different types of research, a wide range of similar analog brackets came into being, however, the traditional analog brackets also have their shortcomings, mainly manifested as difficult to operate the top of the shop, difficult to compaction, etc., resulting in the experimental model Layered uneven, fluffy dregs, increasing the test error. Therefore, a similar simulation bracket with adjustable lifting height was designed, which solved the problems of difficult laying and compaction in the work and saved the working time.
