The mathematics model of joint friction in a mechanical system was presented, in which the action forces in the joint were converted into ideal constraint force and friction moment. 建立了机构运动副摩擦的数学模型,将关节接触面间的作用力转化为理想约束力与摩擦力矩。
An Ideal Way of Life: the Unification of Self-control and External Constraint 理想的生活之道:自制与外制的统一&基于对中国古典哲学重新审视所获得的新生活观
Ideal constraint can be divided into complete ideal constraint or incomplete ideal constraint according as generalized ideal constraint forces equal to zero or not. 对于理想约束,按照广义理想约束力是否为零,把理想约束分为完全理想约束和不完全理想约束。
Here, on the basis of approximating the amplitude-frequency characteristic of ideal difference filter, the optimal coefficients of difference filter are obtained through the modeling by minimized method with constraint conditions. 文章在逼近理想差分滤波器幅频特性的基础上,通过带约束条件的最小化方法建模求解差分滤波器的最优系数。
The ideal constraint force of 1-order nonholonomic constraint 一阶非完整约束的理想约束力
The simulations of lateral guidance loop applying the new equation to some missile have been carried out to verify the new ideal constraint equation, and the results are fairly satisfactory. 以某型号导弹为例,利用这种新颖的平行接近法理想约束方程,进行了航向自导回路的数字仿真,得到令人满意的结果。
The simplest instance is ideal load of bilateral constraints, which means that there is only ideal constraint force during load. 所谓理想加载是指加载中的作用力仅是加载约束的理想约束力。
