Braided composite materials for the production of lightweight, high rigidity golf shafts

Braiding is not currently used in the production of golf shafts. The objective of this work was to develop, through a modelling process consisting of altering lamina sequence, a golf shaft, using braided laminas, which would have mass, stiffness and torque comparable to commercially available composite and steel shafts. A 2D conical braided composite model was previously developed and validated to predict elastic constants of braided closed meshed structures. Energy methods were used to calculate the stiffness and torque of shafts using prescribed industry approaches. Shaft mass was calculated based on geometry and density of constitutent materials. Modelled shafts had both braided and unidirectional layers and compared favourably with or were better than commercially available composite and steel shafts in terms of deflection force and twist angle; they had the same weight as composite shafts but were much lighter than steel shafts. If these findings are verified, braided composites would be a viable and effective approach to the design of future golf shafts.

高尔夫行业工作者心理满意度及应对方式调查分析──以南京为例

研究目的与方法:采用《情感量表》和《应对方式量表》对南京高尔夫球场工作者进行调查分析。研究结果:南京高尔夫行业工作者,专业对口达75%,83.3%是大专学历,月薪2 500元以下占80.6%;工作3年(不含)以上的心理满意度总分显著高于0-3年的工作者(P<0.05),从得分来看,男性心理满意度略高于女性,月薪高的人群心理满意度略高一些;遇到问题时男性比女性更多的采用积极应对方式,而且存在显著性差异(P<0.05)。工作0-3年采取消极的应对方式低于工作3年以上的人且存在显著性差异(P<0.05),月薪2 500以下比2 500元以上更多的采取积极的应对方式,而且存在显著性差异(P<0.05)。     

Correlation between maximum in-shoe plantar pressures and clubhead speed in amateur golfers

Disagreements exist in the literature regarding the manner in which weight should be dynamically shared during the golf swing, both within-feet and between the back- and target-foot, to generate maximal clubhead speed. The purpose of this study was to determine whether preferential foot-loading locations underlie weight sharing by examining the correlation between clubhead speed and maximum plantar pressure (PP) distributions. Thirty-two amateur golfers with handicap indexes ranging from 2.7 to 25 performed 10 driver swings on artificial turf following a warm-up. PP distributions were recorded at 100 Hz, and clubhead speed was recorded using a ball-tracking Doppler radar system. Maximum PPs were extracted from a 2-s window approximately centred on ball contact and were regressed against clubhead speed. Significance was assessed over the entire foot surface using statistical parametric mapping (SPM), a spatially continuous technique. SPM revealed, at relatively high anatomical resolution, significant positive correlations between clubhead speed and PPs in the lateral target-foot (P < 0.05). This suggests that not only weight transfer but also weight-transfer location may be an important determinant of clubhead speed in amateur golfers.     

唐诗宋词中“秋千”意象的三种状态

在唐诗宋词中,涉及秋千的诗词有二百多首,这些数量虽然不多,但是“秋千”意象却是在研究古典文学作品中不可忽视的一个文学意象。“秋千”意象与古代闺阁女性的空间位置在不同的作品中呈现出不同的审美状态,文章主要从这二者之间的空间关系入手,进而梳理分析秋千在三种状态下的审美特征。     

基于校企合作的高尔夫球运动管理人才培养理论与实践研究

我国迅速发展的高尔夫球产业与起步较晚、相对滞后的高尔夫球教育之间产生了巨大的矛盾,高尔夫球专业人才缺口巨大。鉴于高尔夫球项目特点,有必要采取校企合作来进行人才培养。依据我国深化高等教育改革要求和高尔夫球人才培养特征,河北体育学院积极开展校企合作,确立了"院企联合、学训结合、分段教学、特色培养"的人才培养模式,在对该模式理论内涵进行分析的基础上,从基地遴选、共建机制、教学活动和管理工作等方面,对该校高尔夫球运动管理人才培养模式进行研究,旨在为我国高尔夫球人才培养工作提供借鉴。
