【摘要】：伴隨著科技的不斷進步,機械設備越來越向大型化、高速化的方向發(fā)展,同時人們對振動的要求也越來越高,傳統(tǒng)的隔振設備已不能完全滿足減振性能的要求。針對目前的隔振器存在的優(yōu)缺點,結合相關的振動理論知識和自動控制原理,本文研制了一款基于四軸慣性式電磁激振器的雙層主被動復合式隔振器。為了實現(xiàn)振動主動控制的功能,本文專門研制了一款四軸慣性式電磁激振器。此處以電磁激振器的動力學理論基礎為切入點對其進行了動力學分析,并分析了影響電磁激振器輸出力的相關材料及參數(shù)。首先,為了得到最優(yōu)的結構參數(shù),本文利用電磁場有限元分析軟件ANSOFT對激振器的磁路進行了仿真分析;然后,對電磁激振器的散熱不良問題進行了設計,提出了冷卻的方案及計算結果;在此基礎上設計并制造出激振器的樣機,最后對激振器的樣機進行了性能測試。本文根據(jù)振動的理論知識研制出雙層隔振器的被動隔振部分,通過限元分析軟件ANSYS對其結構進行了應力和模態(tài)響應仿真。最后將研制出的主動隔振部分與被動隔振部分組裝在一起,構成整臺主被動復合式隔振器的樣機。在此基礎之上,通過實驗分別測試了激振器的輸入電壓與動子的加速度響應之間的傳遞函數(shù)hi、激振器的輸入電壓與中間隔振板的加速度響應之間的傳遞函數(shù)gij、激振器的動子加速度與中間隔振板的加速度響應之間的傳遞函數(shù)HIJ,通過對實驗數(shù)據(jù)的擬合處理進一步了解了該裝置的性能;此外通過仿真的方法對整臺隔振器的隔振性能進行J了研究,并與前面的實驗結果相對比,提出了改進的建議,為下一步工作奠定了基礎。
[Abstract]:With the continuous progress of science and technology, mechanical equipment is becoming more and more large-scale, high-speed direction, at the same time, people have higher and higher requirements for vibration, the traditional vibration isolation equipment can not fully meet the requirements of vibration absorption performance. In view of the advantages and disadvantages of the current vibration isolators, combined with the related vibration theory knowledge and the principle of automatic control, a double-layer active and passive composite vibration isolator based on the four-axis inertial electromagnetic exciter is developed in this paper. In order to realize the function of active vibration control, a four-axis inertial electromagnetic exciter is developed in this paper. In this paper, the dynamic analysis of the electromagnetic exciter is carried out based on its dynamic theory, and the related materials and parameters affecting the output force of the electromagnetic exciter are analyzed. Firstly, in order to obtain the optimal structural parameters, the electromagnetic field finite element analysis software ANSOFT is used to simulate and analyze the magnetic circuit of the exciter, and then the problem of poor heat dissipation of the electromagnetic exciter is designed. The cooling scheme and calculation results are put forward, and the prototype of the exciter is designed and manufactured on this basis, and the performance of the prototype of the exciter is tested at last. Based on the theoretical knowledge of vibration, the passive vibration isolation part of double-layer vibration isolator is developed in this paper. The stress and modal response of the structure are simulated by the finite element analysis software ANSYS. Finally, the active vibration isolation part and the passive vibration isolation part are assembled together to form the prototype of the active and passive composite vibration isolator. On this basis, The transfer function between the input voltage of the exciter and the acceleration response of the vibrator, the transfer function between the input voltage of the exciter and the acceleration response of the intermediate vibration isolator, and the acceleration of the exciter are tested by experiments. The transfer function HIJ between the degree and the acceleration response of the intermediate vibration isolator is obtained. The performance of the device is further understood by fitting the experimental data. In addition, the vibration isolation performance of the whole vibration isolator is studied by means of simulation, and compared with the previous experimental results, some suggestions for improvement are put forward, which lays a foundation for further work.
