鋸齒形板 的英文怎麼說
中文拼音 [jūchǐxíngbǎn]
鋸齒形板
英文
serration plate-
The results indicate that if the value of press stress is over certain figure, press stress and al plate ’ s thickness have little influence on sawtooth distortion for the same kind of sawtooth ; sawtooth distortion is well - regulated under static press, while it is irregular under impact press. bottom coating make great influence on bond strength of samples which can improve the value remarkably ; bonding mechanism of clad steel is mechanism of mechanical effect that sawtooth which is hooked occludes with al plate
結果表明：同種齒型，當壓應力大於一定的值時，壓應力和覆板的厚度對齒形的變化影響不大；靜壓下齒形變化比較規則，鋸齒頂端向一側彎曲成鉤狀；沖壓下齒形比較凌亂，鋸齒的頂端沒有明顯的變形；后處理對試樣的結合強度影響很大，打底試樣由於粘結層的作用，結合強度較高；機械作用機制是復合鋼板的主要復合機理，鋸齒彎曲成鉤狀和鋁板形成機械咬合。Cfd techniques for the design of plate - fin heat exchangers with plain fins and serrated fins
技術在平直和鋸齒形板翅式換熱器設計中的運用The experiments produced respectively al clad plate by impact & cold press methods under normal temperature. this paper studied the rules of sawtooth distortion, inspected the fibre structure and bond strength of samples, found technics parameters of produce clad plate and analyzed their infections on bond strength
分別利用沖擊法和靜壓法在常溫下制備了覆al復合鋼板，研究了這兩種復合鋼板的鋸齒變形規律，檢測界面顯微組織和結合強度，找到制備復合鋼板的工藝參數，並分析其對復合鋼板結合的影響。And relying on this, our laboratory proposes a new cladding method. by means of large dynamic explicit fem code ansys / ls - dyna, the numerical simulation was carried out in bimetal forming process. during the simulation of the forming process, the large deformation of the strip should be considered, as well as geometrical and material nonlinear, the contact between the roller and the strip, the contact between two metal sheets and the load. as for these problems, we can use node to surface contact and relative parameters, biso model is introduced, the load is applied as array
本文採用ansys / ls - dyna計算程序為分析工具，對鋸齒形雙金屬復合板成型過程進行計算機數值模擬，在對軋制過程模擬時，針對軋件變形的幾何非線性和材料非線性特點、軋輥與軋件間的接觸、軋件間的接觸以及模型的加載等問題，給出了在ansys / ls - dyna中相應的解決方法：應用nodetosurface接觸方式，設定相應參數，選用雙線性等向硬化模型，載荷作為array施加在剛體質心。The results indicate that the time of press influences sawtooth distortion greatly, but infects sawtooth less. root of the sawtooth made by the method of static simulating rolling have no changes hardly, and from the upper distance the changes became, then on the top the sawtooth curves to the opposite direction
結果表明：壓制時間對齒形的變形影響較大，對齒型的影響很小；模擬軋輥壓制的鋸齒，根部一段幾乎沒有變化，是從一段距離開始變形，然後在頂端向相反的方向彎曲；壓製成型后，鋁板厚度的變化很小。分享友人
