用多力的立体模型分析太极拳的技击功能

Analyzing Taijiquan combating Capability by multiple force 3D model

太极拳的技击功能体现在各个招式中,表现在散打和推手练习中。其发力常常是多力并用,联合出击,形式多样。因此,提出了太极拳立体模型的多力系统理论,编写了双力的计算软件,重点分析了太极拳的双力系统。一个广义力有三个力分量和三个力矩分量。双手的力学模型体现两个广义力的打、化、缠的协作效应。多力立体模型简括了人体和接手的构架、平动和转动、外力等因素,软件可用于定量分析太极拳招式的动静态效应。列举了对太极拳招式"手挥琵琶""搂膝拗步"的分析。

The fighting capabilities of Taijiquan are embodied in the postures, which are manifested in Free Combat and Push Hand. Multiple forces are usually applied simultaneously, cooperatively and in various forms. Therefore, this paper develops a multiple force 3d model for Taijiquan, and compiles a double force software, and especially analyzes the double force system of Taijiquan. A general force had three force components and three torque components. Double hand model simulates the punch, resolve, twist effect of two general forces. The 3d modal analyzes the structure, linear and rotatory motions of the body and hand, including the external forces. The software quantifies the static and dynamic effects of Taijiquan postures. Taijiquan postures of Hands Strum Lute and Divert Push Twist Step are analyzed as examples.
