通过 Ansys 软件建立有限元分析模型并进行静力分析,得到了金刚石压机结构在工况下的应力分布及变形情况。其次,将分析模型转换成参数化模型导入到 Ansys Workbench 中,通过对铰链梁结构特点和受力情况的分析,以零件体积和应力较大处的应力值为目标,选择其主要的结构尺寸(如缸底圆弧R 、凸耳宽度 H 等)为设计变量,对 R 和 H 进行优化设计。结果表明:缸底圆弧 R 的大小直接影响底部应力的大小,随着 R 的增大,底部应力逐渐减小,但当 R 增大到70 mm 以后,应力基本不变。凸耳宽度加大,应力减小,但体积相应增大。倒角 D 、d 对应力影响很小,但对体积影响不可忽略。
通過 Ansys 軟件建立有限元分析模型併進行靜力分析,得到瞭金剛石壓機結構在工況下的應力分佈及變形情況。其次,將分析模型轉換成參數化模型導入到 Ansys Workbench 中,通過對鉸鏈樑結構特點和受力情況的分析,以零件體積和應力較大處的應力值為目標,選擇其主要的結構呎吋(如缸底圓弧R 、凸耳寬度 H 等)為設計變量,對 R 和 H 進行優化設計。結果錶明:缸底圓弧 R 的大小直接影響底部應力的大小,隨著 R 的增大,底部應力逐漸減小,但噹 R 增大到70 mm 以後,應力基本不變。凸耳寬度加大,應力減小,但體積相應增大。倒角 D 、d 對應力影響很小,但對體積影響不可忽略。

Finite element analysis model for static analysis was established with Ansys. Stress distribution and deformation in working situation were analyzed.The models were then transfered into parametric models and imported into Ansys Workbench.Hinge sleeve was analyzed on its structure character and stress situation.To optimize the design,volume of parts and stress value at big stress sites was set as targets with major structure dimensions,such as bottom arc R ,lug width H ,as design variables.Results showed that R value directly influenced stress on the bottom. Bottom stress decreased as R increased.When R reached 70 mm bottom stress kept stable.Stress decreased as H increased,but the volume would increase accordingly.D and d had little influence on stress but their influence on volume could not be ignored.
