Description

technical field [0001] The invention relates to the field of vibration suppression in a system, in particular to a self-powered active-passive compound moment of inertia drive control system. Background technique [0002] Vibration is a common phenomenon in life. Engineering facilities and structures often vibrate due to external loads during use, and in severe cases, they will sway or even be damaged. In order to solve various problems caused by the vibration of structures, vibration control technology came into being. [0003] Structural vibration control technology is mainly divided into the following four aspects: active control, passive control, semi-active control and hybrid control. For various engineering structures, a proper safety vibration control system can effectively reduce the dynamic response of the structure and reduce the damage or fatigue damage of the structure. [0004] The motion of a structure usually consists of a combination of translational and to...

Problems solved by technology

However, in the process of technical research and practice, people found that since the active control device needs external energy to drive the work, when the engineering structure is damaged, the power supply is accidentally cut off, which will lead to the complete failure of the active control device.

[0006] To sum up, the structural vibration control system plays an indispensable role, but the existing structural vibration control system has the following deficiencies: First, the translational TMD control device can only control the translational motion of the structure but not the rotary shimmy The control is invalid. Although the translational AMD control device can control the rotary shimmy, the control efficiency is extremely low and cannot meet the requirements of use; Complex frequency modulation has low control efficiency and poor effect on some complex structures, and has disadvantages such as low robustness, low controllability, and small application range; third, the control system has small application range, limited control force output, and control The effect is limited, and the energy utilization rate of the control system cannot be guaranteed, which cannot meet the needs of economy; fourth, although the active (rotation) control device can solve the above three problems, there is a risk of complete failure of the control system for unexpected energy cut-off
