# Industrial Specification: Steering System

## 1. Technical Definition
A mechanical system that controls the direction of movement for soil compactors by transmitting operator input to the wheels or tracks.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **15-25 MPa hydraulic pressure, 0.5-2.5 Nm steering torque at input shaft, -40°C to 85°C ambient temperature**. Failure boundary: **Hydraulic pressure exceeding 30 MPa causes seal extrusion, steering torque exceeding 3.5 Nm results in shaft shear failure at 450 MPa yield strength, temperature below -45°C causes hydraulic fluid viscosity exceeding 8000 cSt**, Mechanism: **Seal failure occurs via extrusion when pressure differential exceeds 5 MPa across seal interface, shaft failure follows Tresca yield criterion at τ_max = σ_yield/2, hydraulic fluid solidification occurs at pour point temperature of -42°C for ISO VG 46 fluid**.

### 2.1 Analytical Physics Model
Governed by the **L10 Bearing Life & Fatigue Model**:

> **Primary Equation**: $L_{10} = (\frac{C}{P})^p$  
> **Engineering Impact**: Predicts mechanical lifecycle before component fatigue.
