针对传统钛合金高尔夫球杆头生产工艺复杂、效率低、成本高的不足,利用钛合金在一定条件下具有良好超塑性这一莫大的优势,开发了钛合金高尔夫球杆头的超塑气胀成形工艺。运用ABAQUS有限元分析软件,对高尔夫球杆头本体部分在钛合金最佳超塑状态下超塑气胀成形的过程进行了数值模拟分析,揭示了成形过程中应力、应变及厚度分布规律,进一步得到该超塑状态下的压力-时间成形曲线,为后续试验提供了有效参考,同时预测了超塑气胀成形高尔夫球杆头工艺的可行性,模拟结果为钛合金高尔夫球杆头超塑气胀成形工艺与模具优化设计提供了理论依据。

The traditional producing technology for titanium alloy golf club head is complex, of low efficiency and of high cost. Using the titanium alloy having good superplasticity under the controlled condition, the method of superplastic bulging technology for producing golf club head was studied. Using the ABAQUS finite element analysis software, the numerical simulation method was applied to analyze the superplastic bulging process for the main body of golf club head under the best superplastic condition of titanium alloy, the distribution rule of stress, strain and thickness during the forming process was disclosed, and the pressure-time curve under the best superplastic condition was obtained, which provided the effective reference for the physical simulation experiment, In the mean time, the feasibility of using the superplastic bulging technology to produce the golf club head was forecasted, according to the simulation result, the theory basis was provided for the superplastic bulging technology of golf club head and the mold optimum design.
