Description
Technical Field
The invention relates to the field of vibration suppression in a system, in particular to a suspension type compound tuning moment of inertia driving control system.
Background
In recent years, with the development of economy and the progress of society, the demands of people for living space are increasing, and the investment of the country in infrastructure is increasing. The national investment in civil engineering is increasingly large, and highways, railways, bridges, high-rise buildings, large-span space structures and the like are continuously built. In addition, people also search and develop wider spaces, search towards deep sea and deep space, and develop structures such as ocean platforms, space stations and the like rapidly. These space structures are inevitably subjected to various loads, both static and dynamic, during construction and later operational use. In the use process of the structure, dynamic load effect is often greatly influenced on the structure, such as earthquake, wind, wave, flow, ice, explosion and the like, the structure can vibrate under the effect of the dynamic load, fatigue and reliability problems can be caused under the general condition, and structural damage and failure can be caused when serious, so that casualties and property loss are caused. In the use process of the structure, after the structure is subjected to dynamic loading action, such as earthquake action, the structure is collapsed and destroyed and cannot be used continuously, or even if the structure is not collapsed, the equipment facilities, decoration and installation systems in the structure cannot be used continuously after being destroyed, and even secondary disasters are caused, so that huge safety threats and economic property losses are caused for users.
On the other hand, with the development of economy and the continuous progress of technology, the demands on the structure are not limited to be usable, and higher demands are also put on the aspects of structural safety, durability and the like. In the use process of the structure, people need to ensure the life safety of the people and meet the requirements of the people on comfort level and the like. For example, the high-rise structure can generate vibration under the action of wind load, under the condition of no vibration reduction and isolation measures, a user at the high-rise can feel shaking of the structure, under the condition of large wind force, equipment and facilities inside the structure can be damaged even by the vibration of the structure, so that the requirements of people on comfort of the structure can not be met, and the threat to economy and property is caused.
In order to solve various problems caused by vibration of a structure, vibration caused by external load is eliminated or reduced, and a vibration control technique has been rapidly developed in recent years. Not only in the civil engineering field, but also in the fields of aerospace, automobiles, machinery, ocean engineering, military engineering and the like, the vibration control technology is a hot spot direction. For the civil engineering structure, the properly safe vibration control system in the structure can effectively lighten the dynamic response of the structure and lighten the damage or fatigue damage of the structure, thereby meeting the requirements of people on the safety, comfort and the like of the structure and achieving reasonable balance of safety, economy and reliability. A large number of researches show that the vibration control technology has remarkable effect and important significance in civil engineering application, not only can prevent or lighten the damage of the structure and improve the disaster prevention performance of the structure, ensure the life and property safety of people, but also can prolong the service life of the structure and reduce the maintenance cost of the structure, and greatly meet the comfort requirement of people on the structure under extreme conditions.
The civil engineering structure vibration control technology is mainly divided into the following four aspects: active control, passive control, semi-active control, and hybrid control. Among them, the study of passive control technology is mature, wherein the device for passive tuned energy absorption mainly comprises tuned mass dampers, tuned liquid dampers and the like, and has been applied to various civil engineering structures. The TMD control principle is that the frequency of the substructure, namely the damper, is adjusted to be consistent or similar to that of the main structure, namely the controlled structure, so that the substructure and the main structure resonate, and vibration energy of the main structure is dissipated through a damping mechanism in the substructure, so that the dynamic response of the main structure is reduced, and the purpose of vibration control is achieved. Numerous studies and practical applications have shown, for example: TMD vibration control systems are installed in John Hancock building, gekko Himalayan double-sub tower building and North China building 101 of Boston 60 layers in the U.S., and the later application proves that the passive control TMD system has stable and good control effect.
The movement form of the structure has complex and various characteristics and is usually formed by combining translation and torsion swinging. However, when the TMD system is used for controlling the swing problem of the suspended mass system, the following steps are found: when the structure suspension direction is consistent with the shimmy movement direction of the structure suspension direction, the TMD system can play an effective control role under the excitation input of initial offset and simple harmonic load; when using a TMD system for shimmy control in another direction of the structure, i.e., when the structure suspension direction is perpendicular to the shimmy motion direction, the TMD system is always inoperable regardless of the adjustment of system parameters (e.g., structure shimmy length, control system position, etc.). Through a great deal of theoretical analysis and experimental exploration, a conclusion is made that the translational TMD control system can only control the translational motion of the structure and is ineffective in controlling the swing and lag. The study of scholars shows that the root cause is that the passive control systems such as TMD, TLD and the like are in a centrifugal state and lose effect, the mass block of the system (or water in the TLD water tank) does not move at all, and even the active control force of the active mass damper/Driver (English name Active Mass Damper/Driver, AMD) control system greatly reduces the control efficiency of the active control force because the gravity component of the mass block needs to be overcome. However, the structural movement forms with gyratory pendulum movement characteristics are very common, such as: torsional shimmy of irregular buildings under the action of wind load; swinging of the suspension structure; torsional shimmy of the ocean platform under the coupling action of sea waves, wind, ice and the like. Therefore, a special structure vibration/motion control system needs to be designed, so that the influence (centrifugal force effect) of a gravity field on the control system can be automatically overcome (or eliminated), or the working/motion rule of the control system is decoupled from the gravity field, the self-vibration of the system is not influenced by gravity, and the purpose of fully moving the control system can be achieved, so that the effective control effect of the control system on the structure vibration is exerted.
In summary, the conventional structural vibration control device has an indispensable role in the civil engineering field, and has a very important meaning for guaranteeing the life and property of structural users. However, existing structural vibration control devices/systems mainly exhibit the following disadvantages: firstly, the translational TMD control device can only control the translational motion of the structure and is ineffective in controlling the swing oscillation; secondly, although the translational AMD control device can control the rotary shimmy, the control efficiency is extremely low, and the use requirement cannot be met; thirdly, the passive moment of inertia tuning damper is effective in controlling the swing and lag motion, but the passive moment of inertia tuning damper needs to carry out complex frequency modulation aiming at the structure, has low control efficiency on certain complex structures, has poor effect, and has the defects of low robustness, low controllability, small application range and the like.
The present invention has been made in such a background.
