球面摆 meaning in English

spherical pendulum

Because the equation has a strong coupling and nonlinear form , it is hard to find out a resolution . then we simplify a double lines pendulum to a spherical pendulum model and set up its mathematical model
由于它具有强耦合性和强非线性，很难求出解析解，因此又将双线摆模型进一步简化成为球面摆模型，并建立了相应的数学模型。
According to the designing plan , the mathematical model of spherical pendulum is more simplified in two aspects , and the results we get has the same form with the mathematical model of simple pendulum . then a rule of kinematical of pendulum in relative coordinate is gotten
本文根据方案中遇到的主要工况将球面摆的数学模型进一步简化为两个主运动方向上的摆动的运动微分方程，简化结果与单摆的数学模型一致，得到了摆锤在相对坐标中摆角的变化规律。
