| 摘 要： | 针对3000kN／7500kN·m操作机钳头夹持机构，分别夹持不同重力、不同夹持力矩的锻件，在钳杆不同转角位置、钳口不同夹持直径等工况下，进行三维建模和有限元仿真。分析在复杂工作条件下各主要零部件的受力状况，得到相应零部件上危险点应力值的变化规律，根据材料力学性能对其进行静强度和疲劳强度校核。结果表明，材料的静强度及疲劳强度完全满足使用要求。

| Abstract: | Three-dimensional modeling and finite element simulation of the 3000kN/7500 kN · m forging manipulator clamping mechanism were established at the operating conditions of different canting weight, different carrying moments, different tongs rotational positions and different clamping diameters. The stress state of the main components under complex working conditions was analyzed. The change rules of the stress value at the risk points on the corresponding components were obtained. Based on the mechanical properties of materials, the static strength and fatigue strength of each component were checked. Results show that the static strength and fatigue strength fully meet the requirement. |
