【摘要】：伴隨著科技的不斷進(jìn)步,機(jī)械設(shè)備越來(lái)越向大型化、高速化的方向發(fā)展,同時(shí)人們對(duì)振動(dòng)的要求也越來(lái)越高,傳統(tǒng)的隔振設(shè)備已不能完全滿足減振性能的要求。針對(duì)目前的隔振器存在的優(yōu)缺點(diǎn),結(jié)合相關(guān)的振動(dòng)理論知識(shí)和自動(dòng)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(dòng)復(fù)合式隔振器。為了實(shí)現(xiàn)振動(dòng)主動(dòng)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(dòng)力學(xué)理論基礎(chǔ)為切入點(diǎn)對(duì)其進(jìn)行了動(dòng)力學(xué)分析,并分析了影響電磁激振器輸出力的相關(guān)材料及參數(shù)。首先,為了得到最優(yōu)的結(jié)構(gòu)參數(shù),本文利用電磁場(chǎng)有限元分析軟件ANSOFT對(duì)激振器的磁路進(jìn)行了仿真分析;然后,對(duì)電磁激振器的散熱不良問(wèn)題進(jìn)行了設(shè)計(jì),提出了冷卻的方案及計(jì)算結(jié)果;在此基礎(chǔ)上設(shè)計(jì)并制造出激振器的樣機(jī),最后對(duì)激振器的樣機(jī)進(jìn)行了性能測(cè)試。本文根據(jù)振動(dòng)的理論知識(shí)研制出雙層隔振器的被動(dòng)隔振部分,通過(guò)限元分析軟件ANSYS對(duì)其結(jié)構(gòu)進(jìn)行了應(yīng)力和模態(tài)響應(yīng)仿真。最后將研制出的主動(dòng)隔振部分與被動(dòng)隔振部分組裝在一起,構(gòu)成整臺(tái)主被動(dòng)復(fù)合式隔振器的樣機(jī)。在此基礎(chǔ)之上,通過(guò)實(shí)驗(yàn)分別測(cè)試了激振器的輸入電壓與動(dòng)子的加速度響應(yīng)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(yīng)之間的傳遞函數(shù)gij、激振器的動(dòng)子加速度與中間隔振板的加速度響應(yīng)之間的傳遞函數(shù)HIJ,通過(guò)對(duì)實(shí)驗(yàn)數(shù)據(jù)的擬合處理進(jìn)一步了解了該裝置的性能;此外通過(guò)仿真的方法對(duì)整臺(tái)隔振器的隔振性能進(jìn)行J了研究,并與前面的實(shí)驗(yàn)結(jié)果相對(duì)比,提出了改進(jìn)的建議,為下一步工作奠定了基礎(chǔ)。
[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.
