脚和地的连续接触面在水平力作用下对太极拳平面模型的影响

TheEffect of Continuous Contact between the Feet and Floor to the Taiji Plane Mechanical Model under Horizontal Force

考虑了脚底连续面积对太极拳力学模型的影响。根据推或拉的情况把连续面分成两部分。脚底的应力为线性分布,但是脚底任何处的应力不能为负值。当某部的应力为零判为失根。由此导出太极拳模型的力学公式,并编制了软件,用以分析临界力。计算了宽弓步侧向稳定力矩。

This article analyze the effect of the continuous feet contact area to the Taiji mechanical model. Based on push or pull, the contact area is divided into two sections. The stress under the feet is set to linear, but nowhere the stress can be negative. The posture loose root when the stress at any section reach zero. We derived a Taiji mechanical model and developed a software to analysis critical force. The normal stabilization torque of wide bow stance is calculated.
