重力载荷 meaning in Chinese

gravity load

Compared with non - slung - load flight , additional aerodynamic load , gravity load should be considered in the slung - load system . so the moment to the gravity center , flight mode and the natural frequency will change
直升机吊挂飞行,与直升机非吊挂飞行状态相比,增加了新的气动载荷、重力载荷,和因此产生的对直升机重心的力矩,其飞行运动模式、低频振荡固有频率均发生改变。
2 . dynamics analysis : by setting up jacon matrix differential coefficient sport is passed to descartes space . it makes terminal executing manipulator produce differential coefficient of acceleration and force in every different coordinates can be got . then the effective inertia , coincident inertia and gravity load of two manipulators are calculated by lagrange method . so generalized joint torque of each joint is got , and along with equivalent driving torque , actual driving torque of each joint can be worked out . 3
动力学分析：建立雅可比矩阵将关节空间的各关节的微分运动传递到笛卡尔空间，使末端执行器位姿产生微分运动，以用于求加速度及力在不同坐标系间的线性变换，再用拉格朗日法计算两机械手的有效惯量、偶合惯量、重力载荷，从而计算得到各关节的广义关节力矩，并与等效驱动力矩共同算得各关节的驱动力矩。
