After analysing several kinds of light - weighting structures through ansys, hexagonal speculum structure is confirmed. in the aspect of the controling of speculum, the paper adopts the brushless dc motor which is partial assembled to drive the point speculum and the inductosyn as angle measuring component is selected, the ad2s80a the system is used to get directly angle and angular velocity. double closed - loop speed and position control is designed, as the pid control is the well - developed algorithm, which can achieve stable rotation and precise position control
在指向反射鏡的擺動控制方面，採用低速性能好的分裝式直流力矩電機作為指向反射鏡的驅動電機，並採用感應同步器作為角度測量元件，運用軸角轉換器ad2s80a進行角度和速度的輸出，採用技術成熟的pid控制方案，進行速度和位置雙閉環控制，以實現指向反射鏡轉動速度的平穩性和位置的精確性。What is mainly discussed in this dissertation is as follows : the fault mechanism and vibration frequency feature of hydroelectric vibration are analyzed, induced and reorganized. the select and placement of detecting positions of parameters such as vibration, swing and pressure pulsation are researched, and the corresponding sensors are selected to monitor
本文主要進行了以下工作：分析、歸納和整理了水電機組振動的故障機理和振動頻率特徵，對機組的振動、擺度和壓力脈動測點進行了選擇和布置，並選用相應傳感器進行監測。We did some analysis about the relativity between the vibration and the noise of the wheel. after the testing of the first line of guangzhou underground, we found that the existing wheel damper has nothing to do with the noise of wheel less than four thousands hz. compared of different contributions of the tread vibration and the web vibration on sound level of railway noise
在實驗過程中，改進了對車輪的激振方式，利用單擺激振提高了激振力的精度;實驗分析了車輪阻尼器的結構、安裝方式及其動力學參數對車輪阻尼器降噪效果的影響;也分析了車輪振動與噪聲的相關性;現場測試廣州地鐵一號線的噪聲特性，確定了車輪阻尼器所要控制的頻率范圍;對比分析不同激振情況下，踏面徑向振動與輻板軸向振動對噪聲聲壓級的貢獻比例。
