Problems solved by technology

But the difficulty is that in the vibration analysis based on ANSYS software, the vibration analysis of the TLD device needs to consider the motion of the fluid and the effect on the wall, and the motion state of the fluid is very complicated and difficult to simulate, resulting in the TLD vibration damping device of the annular water tank. Vibration analysis is difficult

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] The vibration analysis method of the annular water tank TLD shock absorber based on ANSYS software of the present invention, the steps are as follows:

[0017] 1. (1) Create tower equipment finite element model based on ANSYS language

[0018] Segmentation of the tower body is convenient for the establishment of the model. The model establishment ignores some complex accessories inside the tower body. In ANSYS, the specific operation is carried out according to the actual size and commands, and the unit type, elastic modulus and Poisson's ratio are selected according to different requirements. parameters, as follows figure 1 shown;

[0019] After the tower body is created, the built ANSYS tower equipment model is meshed by writing the AYSYS command flow.

[0020] (2) Create the finite element model of the ring TLD shock absorber based on the A...

Abstract

The invention discloses an ANSYS software-based annular water tank TLD vibration analysis method, and designs a simple and efficient annular water tank TLD vibration analysis method on the basis of acentralized mass analysis principle. The method comprises the following steps: 1, establishing finite element models of tower equipment based on ANSYS language and an annular TLD shock absorber; 2, determining mass damping, rigidity damping, constant damping ratio parameters and material physical parameters of the tower equipment based on the ANSYS language; 3, loading transverse wind load or earthquake load and boundary conditions based on ANSYS language; and 4, performing harmonic response analysis and time-history analysis based on ANSYS language. Compared with a complex analysis process, the practical and effective annular water tank TLD modeling method is designed, and the vibration analysis process based on ANSYS software is reasonably achieved on fluid difficult to simulate in an equivalent solid simulation form.

Description

technical field [0001] The invention relates to the field of shock absorbers, in particular to a vibration analysis method of an annular water tank TLD shock absorber based on ANSYS software. Background technique [0002] With the continuous development of the times, the space for human activities has gradually expanded to high altitude and underground. High-rise and super high-rise buildings have become more and more common in recent decades, especially in the chemical equipment and construction industries. With the continuous emergence of high-rise buildings, due to the resonance effect, wind-induced accidents of high-rise buildings also continue to appear, so various vibration reduction devices have also appeared one after another, and the vibration reduction effect of the devices needs to be analyzed scientifically. To get the exact data reference, ANSYS software is widely used in vibration analysis nowadays, but different engineering conditions are different, and the si...
