Fields§

§mu: f64

Friction coefficient μ.

§k1: f64

Thermal conductivity body 1 k1 [W/(m·K)].

§k2: f64

Thermal conductivity body 2 k2 [W/(m·K)].

§rho_cp1: f64

Density * specific heat product ρcp1 [J/(m³·K)].

§rho_cp2: f64

Density * specific heat product ρcp2 [J/(m³·K)].

§t_critical: f64

Critical scuffing temperature Tc [K].

§t_bulk: f64

Implementations§

impl ScuffingModel

pub fn steel_steel() -> Self

Create a typical steel-on-steel scuffing model.

pub fn thermal_diffusivity_1(&self) -> f64

Thermal diffusivity κ [m²/s] for body 1.

pub fn thermal_diffusivity_2(&self) -> f64

Thermal diffusivity κ for body 2.

pub fn flash_temperature_rise(&self, q: f64, a: f64, v: f64) -> f64

Flash temperature rise ΔTf [K] using Blok’s contact temperature formula. q = heat flux at contact [W/m²], a = contact radius [m], v = velocity [m/s].

pub fn contact_temperature(&self, q: f64, a: f64, v: f64) -> f64

Contact temperature Tc = T_bulk + ΔTf.

pub fn scuffing_risk(&self, q: f64, a: f64, v: f64) -> bool

Scuffing risk: returns true if contact temperature exceeds critical.

pub fn safety_factor(&self, q: f64, a: f64, v: f64) -> f64

Safety factor against scuffing (Tc_critical / T_contact).
