摘　　要：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70mm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。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.
