幫我翻譯理工類英文 感恩 關於機械領域 一小段 20點

幫我翻譯一下理工類英文,一小段就好,謝謝! 請懂工程又懂英文的達人挑戰看看! 謝謝

在壓電蜂鳴片金屬背板上60°-120°-180°之角度間距分別鎖上三個直徑2 mm之螺釘,其中螺釘3之位置被作為轉軸直接接觸之驅動點,藉以取代單相薄盤式超音波致動器中直接貫穿壓電蜂鳴片中心之轉軸。由於螺釘是一個完全固定不動之點、在波的傳遞過程中其將會形成一個反射點,且基於螺釘1、2至螺釘3間之行程距離並不相同,因此當沿徑向與弧向往外傳遞至螺釘1及2之行進波在反射過程中,會在螺釘3之位置形成具有時間差之波動,而雙相薄盤式超音波致動器之設計原理即是以此交替性的波動,達到推動螺釘3位置上之轉軸產生旋轉效果。在圖2中,螺釘1、2之位置同樣會有來自另外兩個螺釘所造成之交替性的波動,惟在螺釘1、2上放置轉軸所量測之轉速均較螺釘3位置為低,故我們明確地將螺釘3定義為雙相薄盤式超音波致動器之轉軸驅動點位置,而取名為雙相之意為在每個脈波訊號輸入下會有兩個推動轉軸旋轉之交替性波動。由於來自螺釘1及2之弧向波動為順時針或逆時針方向,將影響轉軸之正逆轉旋轉,故雙相薄盤式超音波致動器與單相薄盤式超音波致動器類似的,在正逆轉的運動控制上並不容易。

不要用翻譯軟體或是google 謝謝

    At the piezoelectric

    metal back-plate, three screws with 2mm diameter are mounted separately at the

    angle of 60°-120°-180°, and the position of the screw 3 is used to be the driven

    point of direct contact point, by which it will replace the shaft that pass

    through the center of the piezoelectric plate in the single phase thin-disc ultrasonic

    actuator. Because the screw is a fix point, and it will becomes a reflection

    point at the progressing of the wave, and based on the different distance from screw

    1 and 2 to screw 3 separately, so when the progressing waves to screw 1 and 2

    along the radical direction and the curve-direction will form a wave with time

    difference when they arrive the position of screw 3. And the design concept of

    two-phase thin-disc ultrasonic actuator is to use this alternative wave to

    achieve the rotation result on the shaft at the position of screw 3. In Figure

    2, the position of screw 1 and 2 will have the same alternative wave from other

    two screws, but the measured rotation speeds that we place shaft at the

    position of screw 1 and 2 are less than the rotation speed that we place the

    shaft at the position of screw 3, so we can define screw 3 as the driven

    position of the shaft of two-phase thin-disc ultrasonic actuator, and the

    meaning named “two-phase” is that each pulse wave input will have two

    alternative waves to drive the shaft to rotate. But the different CW or CCW

    direction of the wave along curve-direction from screw 1 and 2 will affect will

    influence the rotation direction of the shaft, so two-phase thin-disc

    ultrasonic actuator is similar to the single-phase ultrasonic actuator and not

    easy to control the motion of the rotation direction to CW or CCW.

    60°-120°-180° the angle spacing locks bolts of separately the three diameter 2 mm on the piezoelectricity buzzing piece metal back board, the bolt 3 positions are taken driving point of the revolution axis immediate contact, so as to substitutes for in the single-phase thin disc supersonic wave actuating unit revolution axis of the direct penetration piezoelectricity buzzing piece center. Because the bolt will be a completely fixed motionless spot, it will form a point of reflection in the wave transmission process, and based on the bolt will be away from 1, 2 to the bolt 3 traveling schedules is not same, when therefore to will toward the outside transmit along the radial direction and the arc to the bolt 1 and 2 traveling waves in the reflection process, will form in the bolt 3 positions has fluctuation of the time difference, but of principle of design the double-phase thin disc type supersonic wave actuating unit will be by this alternately fluctuation, will achieve impels in the bolt 3 positions the revolution axis to produce the revolving results. In Figure 2, the bolt 1, 2 positions similarly will have will create from other two bolts alternately the fluctuation, in the bolt 1, on 2 will only lay aside rotational speed of the revolution axis gauging to compare the bolt 3 positions to lowly, therefore we 3 will define explicitly the bolt revolution axis of driving point position as the double-phase thin disc type supersonic wave actuating unit, but will name meaning of for the double-phase for will have two impetus revolution axis revolving under each pulse wave signal input alternately the fluctuation. Because from bolt 1 and 2 arcs to fluctuation for clockwise or counter clockwise, will affect the revolution axis to reverse revolving, therefore the double-phase thin disc type supersonic wave actuating unit and the single-phase thin disc supersonic wave actuating unit is similar, in is reversing in the motion control is not easy.
