The friction force is therefore called a nonconservative or a dissipative force. 因此,摩擦力称为非保守力或耗散力。
Based on Lyapunov's stability theory and dissipative structure theory, the stability of isostatic adjustment movement and anti-isostatic movement of crust under isostatic force was analyzed; 根据Lyapunov稳定理论和耗散结构理论,分析了在均衡力作用下,地壳的均衡调整运动和地壳的反均衡运动的稳定性;
Base on the lumped parameter model of the torsional vibration system of crankshafts with variable inertia and considering the nonlinear elasticity force and nonlinear dissipative force, a six-degree-of-freedom nonlinear dynamical equations with parametric excitation and compulsive force are deduced. 从旋转惯量变化的曲轴扭振系统的集总参数模型出发,同时考虑了系统的非线性弹性力和非线性耗散力,导出了参强联合作用下的六自由度非线性扭转振动微分方程。
Aims at these two situations, using dissipative theory and based on backstepping method, this dissertation provides H_ ∞ robust control 、 position passivity control and hybrid force/ position passivity control. 本论文主要就是针对这两种情况,利用耗散系统理论,提出了基于Backstepping设计方法的鲁棒H∞控制、无源位置控制以及混合力/位置无源控制。
Utilizing the dissipative structure theory, the evolutionary process of vibrating liquefaction in saturated granules is analyzed. When the irreversible force increases to some degree, the system will be in a state far from equilibrium, and the new structure probably occurs. 利用耗散结构理论分析了振动液化的演化过程,认为当不可逆力增加到一定值时,系统进入远离平衡状态,新的结构可能出现。
The expressions of hydrostatic force and viscous dissipative force were employed to clarify the relationship between the hole disappearance phenomen and shear thickening effect. 提出了基于流体动力学的简化模型,利用静水压力和粘性耗散力的表达式阐明了初始扰动的消失和剪切增稠效应的关系。
