[求助] 坐标系翻译,急求,多谢

1、速度坐标系。
原点O取在导弹的质心上;ox3轴与速度矢量v重合;oy3轴位于弹体纵向对称平面内与ox3轴垂直,向上为正;oz3轴垂直与x3oy3平面,其方向按右手定则确定。
2、弹体坐标系。
原点O取在导弹的质心上;ox1轴与弹体纵轴重合,指向头部为正;oy1轴在弹体纵向对称平面内,垂直与ox1轴,向上为正;oz1轴垂直与x1oy1平面,其方向按右手定则确定。
3、弹道坐标系。
原点O取在导弹的质心上;ox2轴与速度矢量v重合;oy2轴位于包含速度矢量v的铅锤平面内,且垂直于ox2轴,向上为正;oz2轴垂直与x2oy2平面,其方向按右手定则确定。
4、地面坐标系。
原点A取在导弹质心在地面上的投影点,Ax轴在水平面内,指向目标为正;Ay轴与地面垂直,向上为正;Az轴轴垂直与xAy平面,其方向按右手定则确定。

1.Velocity coordinate system
Select the mass center of the missile as origin O; align ox3 axis with the velocity vector v; make oy3 axis perpendicular to ox3 in the longitudinal and symmetric plane and the positive direction be upward; make oz3 axis perpendicular to the x3oy3 plane and its direction determined by right-hand rule;
2. Missile coordinate system
Select the mass center of the missile as origin O; align ox1 axis with the longitudinal axis of the missile and the positive direction be pointing to the head; make oy1 axis perpendicular to ox1 in the longitudinal and symmetric plane and the positive direction be upward; make oz1 axis perpendicular to the x1oy1 plane and its direction determined by right-hand rule;
3. Trajectory coordinate system
Select the mass center of the missile as origin O; align ox2 axis with the velocity vector v; make oy2 axis perpendicular to ox2 in the plumb plane containing the velocity vector v; make oz2 axis perpendicular to the x2oy2 plane and its direction determined by right-hand rule;
4. Ground coordinate system
Select the projection of mass center of the missile on the ground as origin O; make Ax axis in horizontal plane and be positive when pointing towards the target; make Ay axis perpendicular to the ground and be positive when pointing upwards; make Az axis perpendicular to the xAy plane and its direction determined by right-hand rule
供参考,希望有帮助
