摘要(中) 雙螺桿壓縮機具有高效能與低噪音的特性,常用於許多需節能及高效率能源系統的產業。若能建立一模型可成功預測於循環氣體負載下雙螺桿壓縮機之動態響應,不但可藉其改善系統傳動特性,更可輕易變更螺桿轉子、軸承組及各種工作狀況,預先得知母轉子輸出轉速、轉頻、齒間受力及振動訊號等變化,提供業界有根據之設計參考。因此,本研究提出一種新穎方法建立螺桿轉子與軸承系統之多體動力學模型,其中不僅考慮壓縮機工作腔中循環氣壓施加於螺桿轉子上之變動軸向力、徑向力與變動力矩,亦考量隨轉子接觸曲率半徑變化之赫茲接觸剛度,藉由理論與實驗驗證噴油式雙螺桿壓縮機中螺桿轉子與軸承系統之多體模型動態響應。並於得證後,本文最後利用所建立之多體動力學模型分別探討內部工作腔循環氣壓過壓縮、振盪、50%負載、轉子軸偏位及受壓受熱效應後等九種狀況之動態特性,歸納、整理上述工況改變對母轉子輸出轉頻、齒間受力、振動訊號頻譜有何影響,並提供製造商初步診斷壓縮機噪音來源,給予合理建議以改進其壓縮機之動態特性。
摘要(英) A Study of the Correlation between Geometric and Dynamic Properties of Twin Screw Compressor Rotors under Circulating Pressure Load. High performance and low noise are characteristics of twin screw compressors, and they are often used in many industries that require energy saving and high efficiency energy systems. Establishing a model that can successfully predict the dynamic responses of twin screw compressors under circulating pressure loads can improve the system’s rotational properties, and easily change various working components such as rotor screws, bearing components, gaining preliminary understanding of changes in rotational speed, rotation frequency, tooth load, and vibration signal in female rotors., substantial design parameters for the industry can then be provided. Therefore, this study proposes a new method to establish a multibody dynamics model for rotor screws and bearing systems. Variations in axial force, radial force and moment of force of circulating pressure on rotor screws within the compressor’s working chamber are investigated, Hertz contact stiffness of varying rotor contact on radius of curvature is also examined. Multibody dynamic responses of rotor screws and bearing systems within the oil-injected twin screw compressor are then examined through theory and examination. This study then uses the established multibody dynamics model to examine the internal working chamber’s nine dynamic properties, including excessive compression, vibration, half load, rotor axial deviation, and heat and pressure effects. These property changes are organized and concluded to inspect the effects on the female rotor’s rotational frequency output, tooth load, vibration signal frequency spectrum. The conclusions are provided as substantial suggestions for manufacturers to preliminarily investigate compressor noise source, and improving the dynamic properties of compressors.
