常規泊位選址均以港口為中心進行,而輪渡泊位因為是海上航線和陸上鐵路運輸系統的轉接點,因此選址中比選因素的確定具有特殊性。Owing to the diameters of big and small pulleys are different, while the driving pulley rotates the differential mechanism will not stay at its original place and will make linear movement along the direction of centerline
當主動輪轉動時,由於大小差動帶輪的直徑不同,差動機構就不會停留在原處,而會沿中心線方向上作直線移動。The contacting measurement method with a double probe is put forward after the detailed analysis of the state - of - the - art measuring methods of the thickness of wall. firstly, the theory - profile generatrix is built, and then the movement curve of the track of joint center is constructed, which aims at making the joint center move along the movement curve and keep the fixed sensor touching the wall. the measuring sensor examines the line in its normal direction of the interior wall all the time, the data from the sensor is the thickness value of the wall
論文通過分析國內外變曲率回轉體壁厚測量的現狀,提出了雙測頭接觸式測量方案:通過構造理論輪廓母線,建立鉸鏈中心的運動曲線,使鉸鏈中心始終沿運動曲線運動,以保證固定觸頭與傳感器測頭的連線始終在內壁法線方向上,從而傳感器測頭所得的數值即為壁厚值,該方案經模擬測試實驗取得了預期效果。The slant of support and roller " s axes is analysed as the main factor
對影響回轉窯軸向運動的主要因素? ?托輪軸線與滾圈中心線的傾斜進行了分析。This paper studied two - dimension model of rotor and cylinder and builded the finite element model. generally take the rotor and the cylinder as control objects , definite their boundary conditions , solute their temperature fields , and then analyst their bear expansions and distortions as well as thermal stress distribute , to control the courses , and keep the unit the most optimum operating condition. and put the theories into practice developed by c + + program, used as the important part of the online monitoring and management system of life of the steam turbine
本文對汽輪機轉子和汽缸的二維模型的進行分析,建立有限元模型;將汽輪機轉子和汽缸作為控制對象,確定其邊界條件,求解其溫度場,分析其熱膨脹、熱變形以及熱應力分佈;採用c + +語言編制汽輪機高壓缸、中壓缸以及缸體的溫度場實時在線監測程序,作為汽輪機壽命在線監測與管理系統的核心部分,用以指導汽輪機的啟停及運行過程,使機組可以安全的、經濟的運行。This principle is a lettle like centrifugal pump. when runing, stock enters via the center of tubine wheel, and then under the function of centrifugal force is flung to the direction of tangent and drains out through specified channel
其作用原理類似離心泵,運轉時漿料從渦輪中心吸入,由於離心力的作用,被甩到葉輪的切線方向,經特定的腔道流出。For bilateral symmetry objects, the techniques on symmetry - point detection and symmetry - axis extraction are presented based on harmonic conjugation relationship. for rotated symmetry objects, the techniques on rotated units description and rotated symmetry center extraction are presented based on center invariants of objects. further more, by using 3d invariants and 2d projective transformation, an approach to recover shape from part symmetry objects is realized on some conditions
( 3 )深入分析了2d對稱性目標透視成像的幾何特點,將共點四線交比用於目標輪廓上的關鍵點的特性描述中;利用調和共軛關系,提出了一種針對左右對稱型目標的對稱點檢測和對稱軸提取的演算法;利用交比關系構造了目標的形心不變量,提出了一種針對旋轉對稱型目標的旋轉對稱單元判定、旋轉中心提取的演算法;進一步利用3d不變量和2d射影變換,實現了一定條件下的對稱性目標的形狀恢復技術。The paper analyzed the struture of the tri - eccentric butterfly vavle at length, defined the tri - eccentric butterfly valve, educed the geometry function and its characteristic about the section of the butterfly disc. the results indicate : the parallel contour line across butterfly disc thickness is normal ellipse, thereby eslablished function relations between its geometry parameters ( long axis and short axis ) of three primary sections of the butterfly disc and the tri - eccentricity ; in order to avoid interference between the butterfly disc and the valve seat as well as the valve body, combining the torque, we obtained the feasible range about the rotation center of the tri - eccentric butterfly vavle
本文主要分析了三偏心蝶閥的結構,給出了三偏心的定義,推導出了蝶板截面的幾何方程及其性質,結果表明,沿蝶板厚度的平行截面輪廓線為標準的橢圓形,進而推導出了蝶板幾個主要截面的幾何參數(長軸、短軸)與三個偏心之間的函數關系;考慮到蝶板啟閉過程中避免與閥體及閥座發生干涉,結合蝶板的啟閉扭矩,確立了三偏心蝶閥回轉中心的適宜區域。Using the centerline access bar, spin the check assembly from the 9 o ' clock position to the 12 o ' clock position, then ( without letting go of the access bar ) push the cam assembly slightly downstream so that the clapper is now parallel to the valve body
