hertz_small_strain_error — DRIVE tacdome op

• Data kinds: signal × scalar → table

• Call: import fullseye as fs; fs.ledger.hertz_small_strain_error(d, p: 'float', reading: 'str' = 'derived') -> 'dict' (to call the implementation directly, import tacdome; tacdome.hertz_small_strain_error(d, p: 'float', reading: 'str' = 'derived') -> 'dict'; from the registry, opsdrive.get("hertz_small_strain_error"))

Usage

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

小変形の線形解(Hertz)を大変形に当てたときの誤差 [%] (d だけで決まり、L・寸法・弾性率に依らない)。

`force_from_delta = 1/κₙ − 1(押し込みから力を読む)、radius_from_delta = 1/(a/a_L) − 1、force_from_radius` =

(a/a_L)^{p+1}/κₙ − 1(接触半径から力を読む = 視触覚センサの読み方、平頭は nan)、`force_universal` = 普遍形 (1 − k d)⁻¹ で読んだ力の誤差

κ_universal/κₙ − 1(k·d ≥ 1 は nan)。

Raises `ValueError`: d が [0, 1) の外、p が範囲外。
