快被老闆當掉了,小段機械英文翻譯 拜託達人 20點

一小段工程英文翻譯,很急很急! 拜託懂機械工程又懂英文的達人幫幫忙吧~否則一定會被教授當掉XD 拜託不要用google or 翻譯軟體! 謝謝

如圖4中所示係三相對稱薄盤式超音波致動器之定子結構暨波動示意圖[1],其係三相偏心薄盤式超音波致動器之修正型結構。針對圖3中所示之三相偏心薄盤式超音波致動器,由於其偏心位置在加工製作的過程中並不容易被精確地掌握,且以偏心位置為基準之三區間其實已非完全對稱的120°-120°-120°結構,因此,在每個脈波訊號輸入下所生成的三個交替性波動,其推動力將有某種程度之差異性。為了克服上述之問題,偏心螺釘點被考慮移至壓電蜂鳴片之正圓心位置,而為了繼續保有三分之一波長的行程差或120°的相位差,轉軸驅動點(正圓心位置)至金屬背板上三個螺釘之距離仍將維持為λ/3+d、2λ/3+d、λ+d,基於這兩點修正,壓電蜂鳴片上完全對稱的120°- 120°-120°結構即可被輕易的設計出。

    Figure 4 shows the stator structure and the wave description chart of the ultra-sonic actuator which is three-phase symmetric thin-disc type. It is a modified structure by the ultra-sonic actuator which is three-phase eccentric thin-disc type. To the three-phase eccentric thin-disc-type ultrasonic actuator shown in figure 3, because its eccentric position is not easy to be accurately found during manufacturing, this cause that the three segments based on the eccentric position is not completely symmetric at the structure of 120°-120°-120°, therefore, the driven force of the three alternative waves generated by each pulse signal input will have variation of some level. To overcome the above issue, we consider moving the position of the eccentric screw to the right center of the piezoelectric buzzing plate, and we keep the distances of three screws at the metal back-plate to the center position (shaft position) as λ/3+d、2λ/3+d、λ+d, this is for remaining the traveling distance of one-third wave-length (phase difference of 120 degree). Base on the two modifications, the completely symmetric structure of 120°- 120°-120° on the piezoelectric buzzing plate could be easily designed.

    As shown in Figure 4, three-phase symmetric thin disc Department of ultrasonic actuators cum fluctuations stator structure diagram [1], the Department of eccentric phase thin disc a modified ultrasonic actuator structure. Shown in Figure 3 for the thin disc eccentric phase ultrasonic actuators, because of its eccentric location in the process of manufacture is not easy to capture, and the eccentric position to the three-interval basis in fact incomplete symmetry of 120 ° -120 ° -120 ° structure, therefore, each input pulse signal generated by fluctuations in the three alternating, the drive will have some degree of difference. To overcome the above problems, eccentric screw point to be considered the positive piezoelectric buzzer moved to the circle center, and in order to retain one third of the wavelength of the distance difference or 120 ° phase difference, shaft drive point (positive center of the circle position) three screws to the metal back on the distance will remain for the λ / 3 + d, 2λ / 3 + d, λ + d, based on these two amendments, the piezoelectric buzzer is completely symmetrical 120 ° - 120 ° - 120 ° structure can be easily designed.

    Like in Figure 4 shows is stator of structure and fluctuation schematic drawing [1] the three-phase symmetrical thin disc supersonic wave actuating unit, it is revision of structure the three-phase biased thin disc type supersonic wave actuating unit. Shows the three-phase biased thin disc type supersonic wave actuating unit in view of Figure 3, because its eccentric position is grasped precisely not easily in the processing manufacture's process, and take eccentric position third sector actually already non-full symmetries as datum 120°-120°-120° structure, therefore, produces under each pulse wave signal input three fluctuations, its propelling force will have difference of alternately some kind of degree. In order to overcome the above question, eccentric screw was considered that moves to the piezoelectricity buzzing piece the center of circle position, but to continue holds 1/3 wave lengths the progressive errors or 120° the phase difference, the revolution axis driving point (center of circle position) distances of the three bolt will still maintain to the metal back board on for λ/3+d, 2λ/3+d, λ+d, based on these two revisions, the piezoelectricity buzzing piece finishes attending the holosymmetry 120°- 120°-120° the structure then by the design easily.
