摘要
利用Pro-E、Mechanism/Pro、ADAMS和ANSYS等软件建立了夹持机构的多刚体动力学模型和有限元模型,在考虑摩擦基础上研究了夹持力F0与下倾角φ的关系,分析了不同夹紧力F0夹持额定负载时夹持机构的强度。研究结果表明,综合考虑锻件下倾角φ和关键零件的安全系数n,该夹持机构夹持额定负载时的最优工作夹紧力为240T～250T。研究结果对于提高操作机夹持机构的可靠性以及进一步实现柔性夹持控制具有重要意义。
The multi-body dynamic model and finite element model of gripping mechanism were built by Pro-E, Mechanism/Pro ,ADAMS and ANSYS software based on virtual prototype technology. The relationship between gripping force F0 and forging dip angle ~was researched under the condition of friction, and the strength of key parts with differ- ent clamping force Fo were analyzed. The results showed that the optimal clamping force of gripping mechanism dis- cussed in the paper is 240T ~ 250T for rated load by comprehensive consideration of forging dip angle ~b and safety fac- tor n of key parts. The results can provide certain theoretical significance for improving the reliability of gripping mech- anism and farther realizing the flexible conmol of gripping forging.
