The Golf Club Head Simulation Of Stress State And Material Selection

In this paper, the development of golf products all over the world was reviewed. The manufacturers put a lot of engineering efforts into improving the performance of their products, yet they still depend on physical prototypes and subjective user evaluations to optimize the performance of their designs. This traditional design cycle, design-build-test, result to cost and time increase in products production and can not adapt to modern designing mode.This thesis integrates the computer-aided design software "Solidworks" and finite element analysis software of MSC.Marc to design folg club and investigate the physical phenomenon of impact between golf club head and golf ball. In order to find out the maximum vom mises stress and permitted wall thickness of different materials for golf club, the stress distribution and propagation of different golf club heads are studied. Then try to provide some references for products development and assessment of golf club.In present thesis three golf club head with different shape and size were studied and determined by 3D designing software Solidworks. There volumes were 210cc, 320cc, 380cc each. Then the finite element models are created. Combination with measurement results the material parameters of the golf ball for numerical simulation were determined. The ball core's Yong's modulus is 35MPa and Poisson Ratio is 0.4; the ball shell's Yong's modulus is 270MPa and Poisson Ratio is 0.35. The follows conclusion can be designed for the three golf clubs with different materials and a series of thickness by finite element analysis. The thickness of the club head made of stainless steel should be above 2.5mm, Al alloy should be above 4mm, Ti alloy should be above 2.3mm. Different model and volume of golf clubs will have some difference on the thickness. Proper materials of the club head were gained after hitting simulation for the three different models made of the same material. Al alloy is more adaptive for model 2 and Ti alloy for model 1. Stainless steel is adaptive for the club head of less volume only. Finally, the simulation result compare with the static compacting experiment was studied to verify the analysis above. The results show that the simulated result accorded with the experimental value. They Both appeared a large plastic distortion.. There is a little difference between experimental and simulated values, and the reason have been explainedThe results approved that the theory, technology and the software in this thesis could be used to golf products design.
