| Currently researches on ground simulation test-bed are mostly conducted on small-scale ground simulation test-bed. Because it is not big enough to simulate the geological cross-section change, it may lead to a big deviation result and can hardly dovetail the real situation. However few researched have been done on the development of large-scale simulation test-bed, hence no existing model to learn from. The large-scale simulation test-bed developed in this study is large scale test, lift, and wide applicability, which can be used as a research ground for the research of deformation characteristics of the integrated platform. This major study carried out as follows:To discuss the over all scheme of test bed. Test bed is consisted of an active panel system, a lift system of support panel, a control system and related ancillary support systems as well as other accessories. While working, different subsystems coordinate each other to enable the ascent and descent of panels on the test-bed, by which it can simulate the actual simulation of ground surface deformation.To analysis the application plans of the lifting system. The study reveals that the combination of motor, reducer and lift is a reasonable and feasible solution. The use of turbo-worm wheel lift plus spiral lifting is more secure and stable. Based on data collected from previous research, the coefficient of friction of lifting mechanism is calculated. The design, analysis and checking of various components of spiral lifting and turbo-worm wheel lift, and the match between lifting system and reducer are also presented.Based on the theory of finite element theory, the study uses ANSYS to conduct research on finite element analysis on two key components, triangle panel and six-pointed plate, through which to reveal the stress, strain and overall deformation and propose measures for the improvement and optimization of local structure. |
