为解决航空叶片精锻模具磨损严重,设计参数确定困难等问题,文章在分析模具设计过程和锻造工艺的基础上,基于Archard摩擦理论,借助有限元分析软件对不同设计参数的叶片模具的精锻成形过程进行了模拟仿真,运用正交试验设计方法分析了模具成形角度、桥部厚度、桥部宽度对叶片成形力和模具磨损的影响,得出了有益于叶片成形和减小模具磨损的最优化组合设计参数,并对该参数的计算方法进行了改进,简化了计算过程且参数计算更加精确;最后,通过工程实例对上述过程进行了验证,其实验结果与仿真结果的一致性较好,减小了模具磨损,提高了叶片模具设计效率。
In order to solve the problem of serious wear and tear of the precision forging die of aviation blade and the difficulty in determining the design parameters, the paper analyzes the die design process and the forging process, and based on the Archard friction theory, with the help of finite element analysis software, The forming process was simulated. The influence of mold forming angle, bridge thickness and bridge width on blade forming force and die wear was analyzed by orthogonal design method. Optimize the design parameters and improve the calculation method of the parameters, simplify the calculation process and calculate the parameters more accurately. Finally, the above process is verified by engineering examples, the experimental results are in good agreement with the simulation results, Reduce mold wear and improve blade mold design efficiency.
