ANSYS based digital simulation method of building migration

Abstract

The invention discloses an ANSYS based digital simulation method of building migration for carrying out digital simulation in building migration realized by using hydraulic cylinder jacking. The method comprises the following steps of: programming by using the APDL (Ansys Parametric Design Language) language of the ANSYS, establishing a migrated building model and carrying out statics analysis; extracting the resultant force of bearing reaction forces in an analysis result and the bearing reaction forces of all jacking points; programming a digital road program; setting data actually required to be tested according to the information established by the ANSYS and an obtained result; and carrying out transient kinetics solving to obtain a digital simulation result in the process of the building migration. Compared with the prior art, the invention can be used for carrying out digital simulation of buildings with different lengths and widths and has wider applicability; the road unevenness can be arbitrarily modified, and the influences of various roads on the stress of the buildings can be simulated; the influence of the reaction time of a hydraulic cylinder is added, thus the simulation is closer to the reality; and the powerful analysis function of the ANSYS is utilized, and results are more visual through outputting the graphs of relative results by utilizing the ANSYS.

Description

technical field [0001] The invention relates to a computer simulation technology for building migration, in particular to a simulation method for realizing migration by means of a hydraulic cylinder sliding on a migration track. Background technique [0002] Due to the advantages of low construction cost, short construction period, small impact on people's life and work, and the ability to reduce the pollution of construction waste to the environment, the overall migration technology of buildings has developed rapidly at home and abroad. There are mainly two types in China: one is to lay rollers on the lower track beam to realize the migration by rolling; the other is to connect the hydraulic cylinder at the appropriate lifting position of the bracket, and realize the hydraulic cylinder sliding on the track. migrate. Although the first method is widely used at this stage, it has the following three disadvantages: (1) It has higher requirements on the foundation and track be...

Problems solved by technology

Although the first method is widely used at this stage, it has the following three disadvantages (1) It has high requirements on the foundation and track beams, and the settlement of the foundation and the unevenness of the track have a greater impact on the building

(2) The cost of the track beam is relatively high

(3) The force on the roller is uneven, and the phenomenon that the roller is easily crushed and twisted is easy to occur

The first method lacks precision and versatility

The second method can only be simulated for several cases, and it is difficult to simulate the case of sliding migration
