gimbal lock

英語（米国） (en-US) 英語（イギリス） (en-GB)

名詞

可算名詞 不可算名詞

The loss of one degree of freedom in the three-dimensional rotational movement of a three-gimbal mechanism, which occurs when the axes of two of the three gimbals are driven into a parallel configuration, so that the system's rotational movement becomes two-dimensional (and necessarily remains so until an appropriate force is applied); the equivalent situation in a simulation of rotational movement, when the mathematical model uses Euler angles (representing pitch, yaw and roll) or their equivalent.

日本語の意味

三軸ジンバル機構において、2軸が平行になり、回転自由度が1つ失われる現象。これにより、本来の3次元回転が実質的に2次元の回転運動に制限される。

このボタンはなに？

When the two inner gimbals aligned and restricted rotation, the spacecraft's attitude control encountered gimbal lock, losing one degree of rotational freedom until an external torque was applied.

内部の二つのジンバルの軸が平行になって回転が制限されたとき、宇宙船の姿勢制御は二つのジンバル軸が平行になることで回転の自由度が一つ失われ、適切な外力が加わるまで二次元的な回転に制限される現象に直面しました。

Gimbal lock occurs when the pitch nears 90° or 270°, causing the bank and heading to lie along the same plane. This limits the item to only two rotation axes, as the bank and heading effectively do the same thing.
