Introduction
Background of Standard Revision and Technological Evolution
GB/T 3367.1-2018, as the basic standard of diesel locomotive terminology system, replaces the 2000 version of GB/T 3367.6 standard. The main technical changes are reflected in:
| Technical Field | 2000 Edition | 2018 Edition Update |
|---|---|---|
| Test Methods | 7 Types of Tests | New Traction Thermal Test (2.6.5) and Factory Line Operation Test (2.6.16) |
| Transmission Technology | Definition of AC and DC Transmission | Revise the definition of AC drive diesel locomotive (2.1.14) |
| Structural parameters | Axle type definition | Modify the axle type definition (2.2.1) |
Analysis of core terminology system
2.1 Classification of diesel locomotives
The standard classifies diesel locomotives according to 8 dimensions, among which the classification of technical features has the most engineering value:
- Transmission mode: mechanical transmission (2.1.10), hydraulic transmission (2.1.11), electric transmission (2.1.12)
- Suspension system: primary suspension (2.1.17) and secondary suspension locomotive (2.1.18)
- Speed grade: The definition of high-speed diesel locomotive is adjusted to ≥200km/h(2.1.5)
2.2 Key parameters of structural elements
21 structural parameters are defined, among which the weight parameter relationship is as follows:
| Parameter name | Definition clause | Included elements |
|---|---|---|
| Calculated weight | 2.2.18 | 2/3 fuel + normal coolant + tools |
| Curb weight | 2.2.19 | Full fuel + normal coolant + tools |
| Empty weight | 2.2.20 | Not including crew/fuel/water/sand |
Technical specifications for traction brake system
2.4.1-2.4.30 Traction performance system
Establish a four-level traction force definition hierarchy:
- Diesel engine traction force(2.4.7): Limited by prime mover power
- Transmission traction force(2.4.8): Limited by mechanical transmission capacity
- Adhesion traction(2.4.11): Limit value of wheel-rail friction
- Couple traction(2.4.6): Actual available traction
2.4.41-2.4.71 Braking technology matrix
The standard defines 7 types of braking methods, and the key technologies are compared as follows:
| Braking type | Principle | Applicable scenarios |
|---|---|---|
| Resistor braking(2.4.50) | Kinetic energy→electrical energy→thermal energy | Electric locomotive |
| Hydraulic brake(2.4.51) | Kinetic energy → hydraulic oil thermal energy | Hydraulic transmission locomotive |
| Magnetic rail brake(2.4.52) | Electromagnet friction brake | High-speed emergency brake |
Implementation suggestions and engineering applications
Terminology usage specifications
- AC transmission system should strictly adopt the latest definition of 2.1.14
- Axle weight calculation needs to distinguish between calculated weight (2.2.18) and curb weight (2.2.19)
Test standard implementation
New test requirements:
- The traction thermal test (2.6.5) should include data collection under different operating conditions
- The factory line operation test (2.6.16) needs to verify the dynamic braking characteristics
