【摘要】：目前柔性夹钳的结构设计大多为中间驱动的单载荷输入形式,而实际应用中对夹钳的使用则更需要两端载荷输入的形式。建立了基于变密度法的柔性夹钳的数学模型,采用变密度法对设计区域进行了结构拓扑优化,根据经验法将拓扑优化结果进行了重构,并对优化过程中的重要参数进行了分析,说明了单元格的种类、数量以及体积分数对拓扑优化的重要性。设计出了一种新型的两端夹持力输入的免装配柔性夹钳,并对设计结果的有效性进行了验证,在此基础上提出了一种新的免装配产品的设计思路
[Abstract]:At present, the structural design of flexible clamp is mostly in the form of single load input with intermediate drive, but in practical application, the form of load input at both ends is more necessary for the use of clamp.The mathematical model of flexible clamp based on variable density method is established. The structural topology of the design area is optimized by variable density method. The results of topology optimization are reconstructed according to the empirical method, and the important parameters in the optimization process are analyzed.The importance of cell type, quantity and volume fraction to topology optimization is explained.A new type of assembly free flexible clamp with input of clamping force at both ends is designed, and the validity of the design result is verified. On the basis of this, a new design idea of assembly free product is put forward.
