摘要：

以飞机凸轮盖板零件为研究对象，根据零件的几何尺寸，利用商业Catia软件建立其三维模型，并结合网格剖分软件和Dynaform有限元软件，进行主动式充液成形仿真、试验及微观组织和力学性能研究。基于增量有限元法，根据不贴模和回弹的变形情况，对主动式充液成形中加载与卸载回弹过程的变形进行了工艺仿真分析，设计了主动式充液成形模具，研究了工艺参数对零件成形质量和回弹的影响规律。在最佳的工艺参数下，制备了凸轮盖板零件实物，研究了其周向和法向的硬度值、厚度值和微观组织，并得到了相关的变化规律，为主动式充液成形工艺设计与优化奠定理论基础。

For the aircraft cam cover plate part, according to the geometric dimensions of part, a 3D model was established by using commercial software Catia, the simulation and test of the active hydroforming were conducted,and the microstructure and mechanical properties were studied by combining mesh splitting software and finite element software Dynaform. Then, based on the incremental finite element method and according to the deformation condition of non-die adhesion and springback, the deformation during the loading and unloading springback process in the active hydroforming was analyzed by process simulation. Furthermore, the active hydroforming die was designed, and the influence law of process parameters on the forming quality and springback of part was studied. Finally, under the optimal process parameters, the actual cam cover plate parts were prepared, and the hardness values, thickness values and microstructures of cam cover plate along the circumferential and normal directions were studied, and the relevant change rules were obtained, which lays a theoretical foundation for the design and optimization of the active hydroforming process.
