1液压胀形金属板材的塑性行为表征(英文)显示文摘采用圆形和椭圆形的模具进行液压胀形试验。利用最近提出的椭圆形模具胀形方法来确定等效应力—应变曲线。该方法将ARAMIS系统测得的实验数据与分析相结合。在使用椭圆形模具的液压胀形实验中,随着模具椭圆度的减小,等效应力—应变曲线逐渐远离圆形模具胀形的曲线。通过胀形测试来确定DC04钢板在正次应变范围内的成形极限图。Lucian LZRESCU Dan-Sorin COMSA Ioan NICODIM Ioan CIOBANU Dorel BANABIC 2012中国有色金属学会会刊:英文版2012,22,S2:6
2Compliant Mechanism Synthesis by Using Elastic Similitude显示文摘Compliant mechanisms have several advantages, especially smaller number of elements and therefore less movable joints. The flexural members furthermore allow an integration of special functions like balancing or locking. Especially fiber reinforced materials exhibit a wide range of function integration considering their compliance in passive as well active applications. To take advantage of compliant elements in applications a robust synthesis tool is needed. The synthesis based on topology optimization method or the pseudo rigid body approach leads to complex structures. Considering the use of fiber reinforced material a synthesis approach which leads to less complex structures is more suitable. For building up simple structures, with only one cantilever beam as compliant element(B) a graphical approach using the elastic similitude is the most efficient method. A step-by-step synthesis procedure is presented to synthesize compliant mechanisms with rotatory joints(R) and prismatic joints(P) to develop RRB/PRB- and RPB-linkages. Using the elastic similitude to implement these results into a graphical synthesis algorithm is the innovation part of this paper. It can be shown that this approach leads to a comfortable handling of beam elements during the synthesis, where the two free parameters can be directly coupled to scale and fix the orientation of the beam element. This advantage inherently shortens the development process. In giving an example the focus lies of the experimental approach, which also shows that the simple BERNOULLI beam model is valid and so the synthesis by using the elastic similitude. The method is presented and discussed by using an application for a cup holder mechanism made of fiber reinforced material.HANKE Uwe HAMPEL Peter COMSA Andrei MODLER Niels MODLER Karl-Heinz 2015Chinese Journal of Mechanical Engineering2015,28,4:2
