neco-radiation

日本語

Acoustic radiation power estimators for vibrating surfaces and rectangular plate modes, using point arrays and modal coefficients.

Estimator paths

RadiationCalculator computes a direct estimate from active sample points, normal velocities, and one representative frequency.

ModalRadiationCalculator precomputes simply-supported rectangular plate modes and then evaluates radiation power from active-cell values on that reduced basis.

Usage

Direct point/value estimate

use neco_radiation::RadiationCalculator;

let calc = RadiationCalculator::new();
let points = [[-0.05, 0.0], [0.05, 0.0]];
let velocities = [0.2, 0.2];
let power = calc.radiated_power(&points, &velocities, 0.01, 440.0);

assert!(power >= 0.0);

Reduced plate-mode estimate

use neco_radiation::{ModalRadiationCalculator, RadiationParams};

let params = RadiationParams {
    rho_air: 1.225,
    c_air: 343.0,
    max_modes: 4,
};
let active_cells = vec![(1, 1), (1, 2), (2, 1), (2, 2)];
let calc = ModalRadiationCalculator::new(&params, 5, 5, 0.1, &active_cells, 1.0, 1.0);
let power = calc.radiated_power(&[0.1, 0.2, 0.2, 0.1]);

assert!(power >= 0.0);
assert!(calc.num_modes() <= params.max_modes);
