# Industrial Specification: Automotive Modular Chassis Assembly System

## 1. Technical Definition
Integrated production system for assembling complete vehicle chassis modules

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.8-1.2 MPa hydraulic pressure, 20-40 N·m fastener torque, ±0.1 mm positioning accuracy**. Failure boundary: **Hydraulic pressure exceeding 1.5 MPa causes seal rupture, fastener torque below 15 N·m results in joint loosening, positioning error beyond ±0.3 mm causes misalignment**, Mechanism: **Hydraulic seal failure due to elastomer yield strength limit (Hooke's law), fastener loosening from insufficient preload below joint separation threshold, misalignment from cumulative tolerance stack-up exceeding kinematic constraints**.

### 2.1 Analytical Physics Model
Governed by the **Frame Structural Deflection Analysis**:

> **Primary Equation**: $\delta = \frac{5 q L^4}{384 E I}$  
> **Engineering Impact**: Ensures structural stability for multi-stage machines.
