摘要
Abstract
The multi-mode flexible system is taken as the research object,and aiming at the problem that the multi-mode flexible system generates vibration during operation,which affects the operation performance and positioning accuracy,a method of active vibration suppression of flexible system based on vibration superposition principle and position control principle is proposed.Firstly,the vibration of the system is decomposed by using the principle of vibration superposition,and the vibration state and energy expression of the system are discussed.Then,taking the vibration energy of the system as the index,a selection method of the input displacement to suppress the vibration is given.Then,in order to ensure the positioning accuracy of the multi-modal system after the vibration reduction is completed,a position control method is proposed.In order to verify the effectiveness of the proposed vibration suppression method,a single-input multi-modal system model is established in ADAMS,and then imported into SIMULINK for joint simulation.The effectiveness of the vibration suppression method and its suppression characteristics are discussed.The simulation results show that the proposed method has good vibration reduction effect.Compared with the traditional control method,it has higher robustness,effectively suppresses the vibration of the system and ensures the positioning accuracy of the system.关键词
