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
The third method is complicated to calculate, the ground conditions are not easy to change, and the factor of hydraulic cylinder response time cannot be considered
The fourth method is more complicated to calculate, it is difficult to rely on the powerful calculation function of the software, it is less intuitive and cannot be applied to the migration of the sliding method
The existing fifth method can only analyze several situations, and needs to analyze multiple situations, which requires a lot of calculations, and cannot directly reflect the impact of unevenness on the force of the relocated buildings

Embodiment Construction

[0016] The hardware environment used for implementation is pentium-44.2G computer, 2G memory, 512 graphics card, and the running environment is ANSYS11.0 and Windows XP system.

[0017] The specific implementation of the present invention comprises the following steps:

[0018] 1) Use beam188 to simulate the frame beams and columns, shell63 to simulate the floor, establish an ANSYS wireframe model, apply a gravitational acceleration of 9.8m / s2, constrain all the jacking points on the bracket, and perform static structural analysis (loading activities on the floor). Load, convert the weight of the wall into a line load and add it to the beam element, select the type to be analyzed as Structure, and click SOLVE in the Solution option to solve. The analysis obtains the support and reaction force of each jacking fulcrum, the building gravity and the building the force of the object in this state);

[0019] 2) Extract the jacking force and the total jacking force of each jacking h...

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...
