ellipse_pressure_shifted — DRIVE `tactorque` op

• Data kinds: matrix × matrix × scalar × scalar × scalar → matrix

• Call: import fullseye as fs; fs.ledger.ellipse_pressure_shifted(X, Y, a: 'float', b: 'float', P: 'float', d=(0.0, 0.0)) -> 'np.ndarray' (to call the implementation directly, import tactorque; tactorque.ellipse_pressure_shifted(X, Y, a: 'float', b: 'float', P: 'float', d=(0.0, 0.0)) -> 'np.ndarray'; from the registry, opsdrive.get("ellipse_pressure_shifted"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

半軸 a(x)・b(y)[m] の楕円 Hertz 圧 p0 √(1 − x′²/a² − y′²/b²) [Pa]、P = 2πab p0/3(Johnson 1985 式 4.24)、中心を d にずらす。

b ≫ a で円筒(稜・くさび状)の押し込みに近い形 —— 形状不変の門の 3 つ目。Raises ValueError: a, b, P ≤ 0、X と Y の形が違う。
