Abstract

This research is a comparison of the characteristics of the displacement isolines due to powder-die-wall friction that arise during the compaction of ceramic powders in conventional die. It has been done using the CosmosWorks software package of the SolidWorks simulation software. The results of comparative simulation with FEM showed that the comparison of the displacement isolines and distribution of deformation of the ceramic powders. In the case of conventional uniaxial dry compaction for long length cylindrical green compact, considerable bending of the layers in the form of a cone can be observed. It is symmetry along centerline of cylindrical green compact. The distributions of the deformation of the green compacts (diameter 14 mm, height 20 mm) as a result of conventional compaction under ultrasonic vibration with power 1 and 2 kW are reduced to 4% and 6.5% when compared with conventional compaction without ultrasonic vibration respectively. Thus, density distribution can be minimized by increasing the power of ultrasonic vibration.

超声振动下圆柱形坯体位移等值线特性的比较

本研究比较了陶瓷粉末在常规模具压实过程中，由于粉末与模壁摩擦而产生的位移等值线的特性。使用SolidWorks仿真软件中的CosmosWorks软件包完成。通过与有限元法的对比仿真，对比了陶瓷粉末的位移等值线和变形分布。在传统的单轴干压实长圆柱形绿色压实的情况下，可以观察到相当大的弯曲层在一个锥形的形式。它是沿圆柱形绿色紧凑体中心线对称的。功率为1 kW和2 kW的常规压实与无超声振动的常规压实相比，直径14 mm、高20 mm的青坯在常规压实下的变形分布分别减小到4%和6.5%。因此，可以通过增加超声振动的功率来减小密度分布。
