From the feature of the force and deformation of the tpih, 5 different elements are used to mesh the different zones of the tube, which are structural beam 3d elastic 4, structural pipe plastic straight 20, structural pipe elastic elbow 18, structural shell elastic 4 node 63 and contact 3d pt - to - surf 49 ; the contact problem is assumed to be flexible - to - flexible ; the temperature field is assumed to be body load. a mechanical model corresponding to reality has been established for numerical simulation. based on the above, the 3 - d fem numerical simulation of tpih has been carried out by using the ansys program
針對加熱彎管過程的受力和變形特點，採用三維梁單元、三維塑性直管單元、三維彈性曲管單元、三維殼單元與三維點對面接觸單元等5種不同的單元分別對管毛坯不同區域進行劃分，並對接觸單元採用柔體-柔體的處理方法，將溫度場作為體載荷處理，建立了符合實際的加熱彎管問題數值模擬力學模型：在此基礎上，應用商用軟體ansys對加熱彎管過程進行三維有限元模擬與研究，獲得了成形時推力、彎矩、支撐力大小及其變化趨勢。 -
Equations of mesh, shorting contact line, undercutting limit line, meshing limit lines and the existence conditions, angle between the direction of relative speed and the direction of contact line, induced normal curvature about every point on the contact line are established. moreover, the paper also theoretically analyzed the error of the grinded gear surface. on the basis of the theory, the computer program is worked out to automatically produce the contact line and the boundary curves of mesh. analysis of meshing circs under different parameters can be done so that we can gain the best process condition
首先對漸開面二次包絡理論進行了深入的探討，推導出了兩次嚙合的嚙合方程式、瞬時接觸線方程式、根切界限線方程式、嚙合界限線的方程式及其存在條件，相對運動速度方向與接觸線方向的夾角及接觸線上各點的誘導法曲率；此外，還對磨齒后工件的齒面誤差進行了理論分析；並在理論基礎上編制了相應的計算機程序，自動生成接觸線族及嚙合界限線，對不同參數條件下的嚙合情況進行分析，可以使工藝條件達到最佳狀態；最後研究了磨齒裝置，設計了磨齒機的傳動系統。 -

Translation modes are similarly independent of the rotational support stiffnesses. large contact ratio do not mean lower mesh force. if either the number of sun or ring gear is not multiple of planet gear, system will run effectively, with lower impaction of tooth mesh in and out
研究表明：扭轉支撐剛度的變化影響系統的轉動模態，徑向支撐剛度（行星架的除外）的變化影響系統的位移模態；齒輪間重合度大並不等於輪齒間的受力情況好；行星輪與內齒圈齒數不為行星輪個數的整數被時，輪齒的嚙入、嚙出對系統的沖擊小，系統的效率高。 -
