摘要
基于有限元分析方法,采用Ansys分析软件平台对整体相连齿啮式快开结构进行弹性应力分析、疲劳分析,获得了齿啮式快开结构应力分布规律,通过接触单元法来模拟卡箍齿与啮的接触过程,在满足强度和抗疲劳性能的要求下,以齿啮式快开结构的质量最轻为目标函数,通过有限元优化设计分析方法对整体相连齿啮式快开结构进行优化,优化分析后质量降低了26.97%。
Based on Finite Element Analysis method,applying the ANSYS analysis software platform to deal with elastic stress and fatigue analysis of tooth-quick opening structure. The overall stress distribution is retained. Using the contact element method to simulate the contact behavior between the teeth,under the condition of meet the requirements of strength and fatigue resistance,Establishing the overall minimum weight of the tooth-locked quick-opening structure as objective function,Through the finite element analysis optimization design method,the general weight of quick-opening structure was reduced by 26. 97%after optimization analysis.
