請問"軌跡,傾斜偏轉效應"英文怎麼說 工程類英文 20點

請問這一段中文如何翻譯成英文呢? 專有名詞不會翻沒關係 因為我們書上都有 主要是文法的問題 因為老闆(教授)交代 只好硬著頭皮找管道了 不好意思 麻煩大家了

圖9中所示為三相對稱薄盤式超音波致動器之轉軸與定子接觸點上之橢圓運動軌跡示意圖[1],當轉軸驅動點之螺釘受到來自外圍金屬背板上其他三處螺釘所生成之反射波動影響,會有如圖10中所示之傾斜偏轉行為[1]。造成此傾斜偏轉行為係因壓電陶瓷材料受逆壓電效應產生機械形變,使得壓電蜂鳴片並非一直保持如靜態時之平板狀,而是有如圖11中所示之波動起伏[4],因此即便轉軸驅動點之螺釘被牢牢緊鎖在壓電蜂鳴片上,但因整體壓電蜂鳴片持續在形變(波動起伏),故驅動點螺釘將會有明顯的傾斜偏轉行為產生,而此舉將間接造成其上之轉軸亦會有相同之傾斜偏轉效應。

圖12(a)至(f)所顯示的一系列ANSYS動態模擬圖[4],係以三相對稱薄盤式超音波致動器為例,針對轉軸驅動點螺釘位置進行動態模擬,所得出傾斜偏轉現象之連續圖示,由圖中明顯示看出:轉軸驅動點之螺釘位置並非是完全固定不動的,螺釘內側之傾斜角度有逐步向下降之趨勢,而外側傾斜角度則有逐步向上揚之情況,而此傾斜變動會隨著波動週期呈現一週期性的偏轉行為,此動態模擬結果與圖10中之描述是完全相同的。在圖7所示之實驗架構圖中,預力加載機構設計之目的即是在提供適當的轉軸接觸壓力、避免轉軸產生偏心傾斜旋轉而降低轉速。針對圖12(a)至(f)所顯示的一系列ANSYS動態模擬圖中,可觀察出轉軸驅動點螺釘周圍有起伏不定之波動,此波動與圖5(a)至(h)中所闡述:轉軸驅動點螺釘周圍有三相交替行進波的行為發生,其結果是完全一致的,惟在圖12(a)至(f)中所顯現出之角度係從側面觀察,故相較於圖5(a)至(h)的顯示結果,圖12(a)至(f)並無法明確地指出確實存在有三個振盪的波峰。

    Picture

    9 is the chart of the elliptical movement trace of the contact point between

    the stator and the shaft on the three-phase thin-disc ultrasonic actuator[1].

    When the screw of the driven point of the shaft sustains the influence of the

    reflection wave generated by other three screws on the outer metal back-plate,

    it will have the behavior of deflection at a angle as shown in picture 10[1].

    The root cause of this deflection behavior is due to that the created

    mechanical deformation of the piezoelectric material by the piezoelectric

    effect will cause piezoelectric buzzing plate unable to sustain at plate-state

    as the plate is static, so it will become the shape of wave-ripple as shown in

    picture 11. Therefore, even the driven-point of shaft is firmly locked at the

    piezoelectric buzzing plate, but the total piezoelectric plate is continuing

    deform (wave-ripple), so the screw at driven point will have obvious behavior

    of deflection at a angle, and this will indirectly cause the shaft on the screw

    have the effect of the same deflection at the same angle.

    先來第一段,等下再補第二段。

    2010-05-14 14:45:33 補充:

    Picture 12 (a) to (f) shows a serial of dynamic simulation charts of ANSYS, it is an example by three-phase symmetric thin-disc ultrasonic actuator. By the dynamic simulation of the screw position at the rotation shaft, we can get the continuous charts about the phenomenon of deflection.(…在意見中)

    2010-05-14 14:46:20 補充:

    From the picture we could clearly see that the screw position of the driven-point on the rotation shaft is not completely fix, and the tilt angle at the inner side of the screw will have the trend to gradually go down, but the outer side of the screw will have the trend to gradually go up. …用寄的…

    2010-05-14 14:46:33 補充:

    And this tilt variation will have periodical deflection behavior along with the wave period. This dynamic simulation result is the completely same as the description in picture 10.

    2010-05-14 14:46:59 補充:

    At the experimental structure as shown in picture 7, the purpose of the design of preloaded mechanism is to provide appropriate contact pressure to the shaft, and to avoid the eccentric deflection rotation by the shaft, in order to reduce the rotation speed.

    2010-05-14 14:47:50 補充:

    In the serial of ANSYS dynamic simulation chart as shown in picture 12 (a) to (f), we could observe that there is ripple wave around the screw position of rotation-shaft, this ripple wave is the same as the description in picture 5 (a) to (h),

    2010-05-14 14:48:10 補充:

    which shows that there are three-phase alternative progressing wave generated around the screw position of the rotation-shaft. But the angle in picture 12 (a) to (f) could not be observed from the side-view,

    2010-05-14 14:48:25 補充:

    so comparing to the result of picture 5 (a) to (h), the picture 12 (a) to (h) could not clearly indicate the actual existence of the peaks of three cycles.
