要提出改進(jìn)的方案并進(jìn)行驗(yàn)證。 對(duì)計(jì)算結(jié)果進(jìn)行分析,有可能需要調(diào)整計(jì)算方案,也是難點(diǎn)之一,既需要經(jīng)驗(yàn)也需要知識(shí)。一般不推薦一個(gè)焊點(diǎn)只采用一個(gè) RBE2單元(只有兩個(gè)節(jié)點(diǎn)連接)的方式。此種辦法比較簡(jiǎn)單,而且焊接順序可以結(jié)合車(chē)間的焊接順序進(jìn)行,比較容易理解,建議初學(xué)者使用。 最小四邊形內(nèi)角:大于 40度216。Create Final Mesh216。 Select free edge216。 Set tolerance to .1216。Pseudo surfacesInitial MeshCompany ConfidentialUser Scenario 1216。 Reduce cost216。便于以后添加材料性質(zhì)卡和辨別零件??梢詫?N個(gè)面合并成一個(gè)面(此種方法只限對(duì)模型質(zhì)量要求不高的情況),但關(guān)鍵的特征線應(yīng)該保留,如拐角、和孔等。 Drastically reduce analysis modeling time216。Verify : Surface : Boundary216。Pseudo surface cleanup216。 2 gaps needs to be manually stitchedMake CongruentCompany ConfidentialUser Scenario 1216。Merge pseudo faces to eliminate skewed or sliver surfaces216。216。 Company ConfidentialIRREGULARITY CHECKSn General mesh/element checksu Boundary or “Crack” detectionu Elements Duplicationu Normalsu Nodal connectivityu Jacobiann Element specific distortion checksu Deviation form basic shaped elements, . tapern Curvature and singularity tests for quadratic elementsn Colorcoding based on node or element ID numbersCompany ConfidentialVERIFY ELEMENT BOUNDARYn Plots the boundary as free edges, or optionally free facesn Free edge/face of an element is the edge/face of the element not m
