| 1 | 多相材料结构拓扑优化:体积约束还是质量约束?显示文摘针对拓扑优化设计中多年沿用的体积约束作为控制材料用量的思路,研究了采用质量约束开展多相材料结构拓扑优化的新方法,提出了相应的质量约束结构优化问题模型和材料插值模型.通过研究广义SIMP模型和对等混合模型两类多相材料属性插值方法,发现广义SIMP插值模型导致质量约束具有复杂的非线性特征,给优化问题的全局寻优和数值求解带来困难;采用的线性对等混合材料插值策略保证质量约束函数具有线性和变量可分离特征,为拓扑设计问题的数值求解,特别是凸规划寻优提供了极大便利.算例表明多相材料插值策略和结构优化模型的正确性和有效性;优化设计结果的比较说明了使用质量约束相对于体积约束的合理性和必要性,阐述了质量约束在解决结构轻量化布局设计问题的有效性以及所带来的显著收益. | 高彤 张卫红 Duysinx Pierre | 2011 | 力学学报2011，43，2： | 10 |

| 3 | Modeling joints with clearance and friction in multibody dynamic simulation of automotive differentials显示文摘Defects in kinematic joints can sometimes highly influence the simulation response of the whole multibody system within which these joints are included. For instance, the clearance, the friction, the lubrication and the flexibility affect the transient behaviour, reduce the component life and produce noise and vibration for classical joints such as prismatics, cylindrics or universal joints. In this work, a new 3D cylindrical joint model which accounts for the clearance, the misalignment and the friction is presented. This formulation has been used to represent the link between the planetgears and the planet carrier in an automotive differential model. | Geoffrey Virlez Olivier Brüls Emmanuel Tromme Pierre Duysinx | 2013 | Theoretical & Applied Mechanics Letters2013，3，1： | 0 |
