重载锻造操作机钳杆夹持机构优化设计

Optimization Design of the Clamp Mechanism in the Heavy-duty Forging Manipulator

钳杆夹持机构能否安全稳定的工作是锻造操作机设计是否合理的关键。建立夹持机构传力比和钳口夹持力的数学计算模型,并通过ADAMS软件对80t锻造操作机钳杆机构虚拟样机进行参数化建模,以夹持力最大为优化目标,建立约束条件对机构参数进行优化分析。通过分析钳杆机构中每个参数变化对夹持力的影响程度,确定影响夹持力相对较大的参数进行机构的优化设计。对优化后机构的夹持性能进行验证分析,结果表明其性能显著提高。

If the gripping mechanism of clamp lever can work safely and steadily is the key to the forging manipulator design. The mathematical models of the gripping force and force transmission ratio for the gripping mechanism are set up, and the par-ametric model of the virtual prototype for the clamp mechanism of the 80t forging manipulator is set up through the ADAMS software. Taking maximizing the gripping force as the optimization goal, constraint conditions on the parameters for optimiza-tion analysis is established. Through analyzing the degree of influence of each parameter in the clamp mechanism on holding force, the parameter that affects the gripping force is conformed for the mechanism optimization design. The performance anal-ysis of the optimized gripping mechanism is verified, the results show that its performance is improved significantly.
