The newly designed javelin with low centre of gravity approved recently by IAAP for man was studied in a wind tun-nel. Results show that the arm of force from the javelin centre of gravity to the centre of air pressure has little to do withthe initial speed of javelin, it varies considerably with the variation of the angle of release; so does the ratio of lift anddrag, it gains only with the increase of the angle of release and goes to the maximum when the release angle is 25°.

The newly designed javelin with low centre of gravity approved recently by IAAP for man was studied in a wind tun-nel. Results show that the arm of force from the javelin centre of gravity to the centre of air pressure has little to do withthe initial speed of javelin, it varies considerably with the variation of the angle of release; so does the ratio of lift anddrag, it gains only with the increase of the angle of release and goes to the maximum when the release angle is 25°. Com-pared with old javelin, the new one with low centre of gravity has a greater value in pitching moment. It is suggested thatfor a better aerodynamic effect during javelin flying, the release angle should be properly reduced.

本文对国际田联改型男子标枪(俗称低重心标枪)的风洞实验进行了分析认为:标枪重心和空气压力中心之间力臂值和出手初速关系不大,它随迎角的变化有较大变动。升阻比和出手初速关系不大,它随迎角的加大而增大,迎角25°时达最大值。低重心标枪和旧标枪相比俯仰力矩绝对值增大,标枪飞行要获得适宜的空气动力效应。投掷时可适当减小出手迎角。

A mathematic model was established based on the initial conditions for the flight of the javelin, the aeromechanic characteristics of the javelin obtained in wind tunnel experiment and the physical parameters of the javelin. Using the computer simulation, the optimum release angle and shot angle of the new model woman javelin were determined. Meanwhile, the main factors affecting the lift-drag ratio and the value of force arm of the javelin were identified.

本文依据投掷标枪飞行的初始条件,结合风洞实验所获取的标枪空气动力学特性及标枪的物理特性参数,建立数学模型,用计算机模拟投掷标枪的方法,揭示出投掷新型女子标枪的最佳出手角及迎角,同时指出了影响标枪的升阻比及空气动力力臂值的主要因素.

In this paper, the orientation of the instantaneous center of rotation (ICR)with respect to the ankle joint was determined by using the fitting of a third degree spline function. According to the definition of arm of force (AF)of muscle, the AF at ICR of triceps surae corresponding to esch rotation angle of ankle joint were calculated. Finally, with the ICR position and the data of AF,a nonlinear regression equation of rotation angle of ankle joint was established using variance analysis and nonlinear regressive...

Finally, with the ICR position and the data of AF,a nonlinear regression equation of rotation angle of ankle joint was established using variance analysis and nonlinear regressive method with poly variables.

用分段三次样条拟合计算了踝关节瞬时转动中心(简称瞬心)的位置,并根据肌力臂的定义,计算出不同踝关节角度时,小腿三头肌相对于瞬心的力臂。再按照统计学原理,对所得瞬心位置和肌力臂数据进行方差分析,利用多元非线性回归方法最终建立了肌力臂与踝关节形态参数及关节角度的非线性回归方程。
