Structural optimal design for hinge sleeve of cubic press

本文以有限元法作为结构分析手段,采用敏度分析技术,在考虑疲劳强度的条件下,完成了铰链梁的结构优化设计,为金刚石六面顶压机关键零部件的设计提供了一套较为完整的设计方法和设计系统。利用ANSYS的APDL参数化语言,编制了铰链梁的结构优化设计程序ODPST,采用零阶优化方法进行了铰链梁的结构优化设计,得到了精确可靠的设计参数,有效地提高了铰链梁的抗疲劳性能和强度。

By means of the structural analysis and taking into account of the fatigue intensity, the struetural optimal design of the hinge sleeve of cubic press were conducted based on the sensitivity analysis technology. A comparatively complete design method and system for the key parts of the diamond syuthesising cubic press realized. Using the APDI, language of ANSYS, the structural optimal design prngram ODPST is programmed. Taking the CO （0-step） method, the accurate and reliable design parameter can be obtained. This improves the fatigue intensity of the hinge sleeve effectively. In the optimization process, the sensitivity analysis technology is used to improve the ealculation efficiency.
