摘要
以人体系统为原型,开展了人体系统运动过程中的人体系统变质量力学基础研究。主要内容有人体系统变质量力学基本概念;人体系统变质量块体质点动力学基本方程;人体系统变质量块体质点动力学微分方程;人体系统变质量块体质点的动量定理;人体系统变质量块体质点的动量矩定理和人体系统变质量块体质点的动能定理,为建立人体系统变质量力学的数字化模型提供理论基础。
The basic study on varing-mass mechanics of human body system in the process of human body system motion was done in this paper, using human body system as prototype. The contents are the basic concepts of varing-mass mechanics of human body system; the basic dynamical equation of block particle of human body system varing-mass; the dynamical differential equation of block particle of human body system varing-mass; the momentum theorem of block particle of human body system varing-mass; the momentum quadrature theorem and the kinetic energy theorem of block particle of human body system varing-mass. It provided theoretical basis for the construction of digital model of varing-mass mechanics of human body system.
