一小段理工類英文翻譯 不難 20點 謝謝

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

在薄盤式超音波致動器的原始設計概念中,螺釘位置被視為是一個完全固定不動之點,然而若將轉軸驅動點之螺釘位置進行ANSYS的動態行為模擬與分析,將會發現其並非完全固定不動。此處我們僅只針對轉軸驅動點之螺釘位置進行動態行為模擬、而未包含壓電壓電蜂鳴片金屬背板上的其他三處螺釘,係因轉軸驅動點之螺釘被建構在壓電陶瓷材料及金屬背板上,而壓電陶瓷材料是整體薄盤式超音波致動器的振動源,但外緣的三處螺釘僅是被固定在金屬背板上、並未直接與壓電陶瓷材料有所接觸。

三相對稱薄盤式超音波致動器在輸入脈波電壓振幅為15 V、輸入電流振幅為0.2 A、轉子重量為100 g、Preload為30 gf及耗電量為1.5 W的條件下,展現出3500 rpm以上的穩定轉速,而此轉速值已足夠與Intel Pentium 4-2.67 GHz CPU散熱風扇之轉速匹敵。雖然三相對稱薄盤式超音波致動器僅能做單一方向的轉動,若考量設計為高速旋轉風扇,則僅能單一方向旋轉之特性將不會影響其應用面。本文中所提出的三相對稱薄盤式超音波致動器具有低電壓輸入、低耗電量及高轉速等優異特性,尤其低至12~15 V的電壓輸入,能輕易地自3C產品的電路系統中擷取到相對應的訊號,大幅簡化了驅動電路的設計並節省安置驅動電路的空間,對於未來應於於3C產品上將有非常大的前景可期待。

    At the original design of the thin-disc

    ultrasonic actuator, the screw position is considered as the completely fix

    point, but if we do the ANSYS dynamic behavior simulation and analysis about the

    screw position at the rotation shaft, we will find that it is not completely

    fix. Here we only consider the screw position at the driven-point, not

    including the piezoelectric buzzing plate and the three screws at the metal

    back-plate, it is due to the fact that the screw at the driven-point of

    rotation shaft is constructed on the piezoelectric ceramic material and the

    metal back-plate, and the piezoelectric ceramic plate is the vibration source

    of whole the thin-disc ultrasonic actuator, and the other three screws are only

    mounted at the metal back-plate, not directly contact with the piezoelectric

    ceramic material.

    The three-phase

    symmetric ultrasonic actuator with the voltage amplitude of 12V, input current

    amplitude of 0.2A, rotor weight of 100g, Preload of 30gf and consumption power

    of 1.5W has the performance of high stable speed of above 3500rpm, then this

    rotation speed is enough to compete with the Pentium 4-2.67 GHz CPU fan.

    Although three-phase symmetric ultrasonic actuator could only rotation at

    single direction, but if for consideration of high-speed rotation fan, then the

    characteristic of single-direction will not impact the aspect of application.

    The three-phase thin-disc ultrasonic actuator in this text has the advantages

    of low voltage input, low power consumption and high-speed rotation, especially

    the low voltage up to 12~15V could easily be obtain from the circuit system of the

    3C product, which could dramatically simplify the circuit design and save the

    space of driving circuit. It has a very great outlook at the future application

    on the 3C product.
