Study of Impact Sound of Golf Club Head

Lin, Shih-feng 06 September 2010 (has links)
With the popularity of golfing, the marketing of golf clubs has been promoted in recent years. The purpose of this study is to investigate the sound effects of golf impact on different shapes and thicknesses of striking face of the golf club using the finite element method. The researcher found that the vibration model and the resonance frequency of golf club heads. In addition, the researcher used vibration modal analysis to generalize the golf head modes with the distribution of the sound pressure. He also used acoustic transient analysis to check the sound pressure level. Finally, the correlations among the sound pressure, sound pressure level and sound frequency of the golf club head impacts were administered. After all, the study findings provides golf head designers and producers with a reference for designing, revising and producing comfortable and qualified impact sounds of golf club heads.

Impact Analysis of Various Centers of Gravity in the Golf Club Head

Chen, Kuan-hong 29 August 2010 (has links)
The center of gravity (CG) in the golf club head is crucial to the launch angle, launch velocity and spin of golf balls after the golf impact. The CG locations in this study refer to the depth of CG, height of CG and distance of CG, which were determined by the change of shell thickness of a golf club head. By means of the finite element method (FEM), the researcher analyzed the impact process for golf balls and golf head clubs. Then he discussed the relationship between club heads and ball behaviors after impact. He also simulated the trajectory by the numerical method on the basis of the impact results of the golf ball. To sum up, a longer carry was generalized by deeper CG, lower CG and higher loft angle for a golfer with a slow club head speed. A shallower CG, higher CG and lower loft on a club head for a golfer with a fast club head speed were also verified in this study. Finally, a series of impacts produced by FEM and numerical method were generalized. Specifically, the method can be used to predict the flying distance of golf ball. It also can help predict the proper CG locations for golf club head designing.

Analysis of impact effect to Varied shape of Golf Club head

Chang, Ting-jang 07 July 2004 (has links)
The purpose of this study is to investigate the function of the different structural designs of golf club head models (including a deep head, a shallow back, and a shallow head) and to get the optimum golf club head through the software simulation. By means of software SolidWorks, the researcher draws three main club head models. The C ++ was used for a linear programming to control the golf club head thickness including an impact face, a crown, a sole, a toe and a heel under the definite weight. The simulation also helps adjust the center of gravity position of the golf club head and integrates with the finite element method software LS_Dyna in analyzing the impact procedure between the golf club head and the golf ball. In addition, the researcher preceded the analysis by replacing the crown surface as carbon fiber reinforcement polymers (CFRP). He also investigated the off-centered hit effects through the impact analysis. It is expected that study findings can be extracted. Through the simulation of the hit effects, the golf club head designers will be inspired to create more effective golf club heads.

The optimal pricing strategy of golf clubs' membership

Hsu, Pei-chi 17 July 2004 (has links)
Due to the increasing of substitution and competition of products, the life cycle of products is shorter than previous time and the perishable has becoming visible for service industry and other related manufacturing industries. Wrong strategy and management of pricing make many companies lose the right opportunity to invest and even trapped in the bad financial structure with the apparent character. More and more private club managers use the concept of yield management to deal with their problems and maximize their benefits because of the property of perishable in recent years. However most researchers study about ways to improve the performance and to understand the distribution of consumers¡¦ recognition instead of realizing the factors impacting the products¡¦ pricing. I will develop an initial pricing model and find out how the relationship among the factors which influence the products¡¦ pricing interacts by this model

Organizational Innovation - A Case Study of the Traditional Industry in Taiwan

Huang, Tz-Jing 25 July 2005 (has links)
21st century has been the so-called the era of knowledge-based andinnovation-driven economy. As Taiwan has been stepping into the stage of slower growth, the major issue for Taiwan¡¦s future development is how we progress toward the innovation-based industrial growth. Facing the hypercompetitive future, staying efficient, keeping costs down, delivering products and services on time and to a sufficient standard of quality are goals that merely ensure the organization stays alive. Continuous innovation has been widely regarded as the major source of competitive advantage and the base on which an enterprise builds its core competence, uplifts its competitiveness and expands its global market share. With the recognition of the importance of organizational innovation, the purpose of the study is trying to examine the current status of organizational innovation in Taiwan's traditional industry, hoping to provide some guidelines for the industry to enhance its competitiveness via innovation. The research suggested two main steps to enhance the innovation system: (1) examine and evaluate a firm¡¦s existing organizational innovation and (2) reconstruct the innovation system. After the analysis of Taiwan¡¦s traditional industry, the guidelines to improve organizational innovation include: (1) improving administrative innovation, (2) improving information system, (3) collaborating with external organizations, (4) developing brand names, (5) developing disruptive innovation, and (6) reinforcing flexibility and adaptability.

Analysis of Golf ImpactPhenomenon and Club Head Design

Shian, Han-Lin 22 June 2000 (has links)
The purpose of this study is to integrate the efficiency of the computer-aided design software Pro Engineer and the finite element analysis software LS-DYNA on the structural design of the golf club head. By means of the parametric design characteristics of Pro Engineer, various thickness and different shapes of the golf club head have been studied. The impact model will extract the ball velocities and spins for a given hit location on the club face which is analyzed by the software LS-DYNA. After that, the factors for influencing the dynamic analysis, such as the thickness and the shape of the hitting face, the off-center hitting, the ball velocity and spin, the stress distribution, and stress propagation in the head are further identified and measured. Finally, the effects of the factors described above have been analyzed quantitatively to investigate the maximum velocity of the ball and the sweet spot of the golf club head.

Development of a Strain Energy Storage Mechanism Using Tension Elements to Enhance Golf Club Performance

Whitezell, Marc A. 23 March 2006 (has links) (PDF)
The development of current golf club designs has followed an evolutionary process starting with the original wooden heads of a hundred years ago, to the thin-walled, hollow body titanium heads of today. Current designs utilize what has become known as the trampoline effect to increase the efficiency of the ball-club impact, which has a number of limiting factors that restrict clubhead performance. These limitations provided the motivation for this research to explore new mechanisms by which the efficiency of the ball club impact could be increased. In particular this research focuses on the development of compliant mechanisms to increase club performance. The results of this research, from concept development to initial prototype plans, are included in this study. A discussion of past and current research in the area of golf club design is presented. A new list of performance metrics for golf clubs and a number of new golf club concepts is also presented. This is followed by a static and dynamic analysis of the most promising golf club configuration. The study is concluded with a concept validation analysis and a presentation of possible prototype configurations for a new golf club design.

Augmenting a National Register nomination for the Augusta National Golf Club course

Wright, John J. January 1996 (has links)
This study has presented a thorough investigation of the integrity and the significance of the Augusta National Golf Club Course from 1934 to the present. The golf course still reflects the design philosophy of Alistair Mackenzie. Design features that have been retained provide this evidence. The hillocks and hollows in the golf course were identified to show Mackenzie's influence in the golf course of today. Changes have been made to Mackenzie's original design. Some changes caused great strategic and aesthetic differences in the golf course. Other changes were necessary due to the spectator and the demands of providing optimum on-site viewing of the Masters Tournament held anually at the Augusta National Golf Club Course. The modifications to the course were responses to the evolving game of golf as played in 1934 as compared to 1996. The significance of the golf course with respect to its Master Designer, Alistair Mackenzie, was shown to be sufficient to warrant the augmentation of its National Register status. Treatment of the landscape is suggested based on the criteria set forth in the study. / Department of Landscape Architecture
