What is a crankshaft bending fatigue testing machine?

In the fields of industrial manufacturing and mechanical design, the crankshaft is the core component of the engine, and its durability and reliability directly affect the overall performance of the equipment. In order to ensure the stability of the crankshaft under long-term high-load operation,Crankshaft bending fatigue testing machineIt came into being. This article will introduce in detail the definition, working principle, application scenarios and technical parameters of this equipment, and discuss its industry value based on recent hot topics.

1. Definition of crankshaft bending fatigue testing machine

What is a crankshaft bending fatigue testing machine?

The crankshaft bending fatigue testing machine is a testing equipment specifically designed to simulate the alternating loads experienced by a crankshaft during reciprocating motion. It tests the fatigue life, crack growth rate and fracture characteristics of the crankshaft by applying periodic bending forces. Its core goal isVerify the fatigue resistance of crankshaft materials, providing data support for optimizing design and production processes.

2. Working principle and structural composition

Testing machines usually consist of the following modules:

module nameFunction description
Load systemApply cyclic bending force hydraulically or electrically
control systemAdjust load frequency, amplitude and number of cycles
sensor unitReal-time monitoring of stress, strain and temperature changes
data acquisition systemRecord fatigue crack initiation and propagation data

The workflow is: sample installation → parameter setting → cycle loading → data recording → result analysis.

3. Application scenarios and technical indicators

This equipment is widely used in the fields of automobiles, ships, and aerospace engines. The following are typical technical parameters:

Parameter itemscope
Maximum load10-500kN
frequency range0.1-50 Hz
Sample length200-1500mm
Test accuracy±1% FS

4. Industry hotspot relationships

Hotly discussed on the Internet in the past 10 days"Lightweight New Energy Vehicles"Directly related to crankshaft fatigue performance:

  • Hotspot 1:Tesla’s new alloy crankshaft passed 2 million fatigue tests, and the testing machine data became a technical highlight
  • Hotspot 2:A domestic car company’s recall due to a broken crankshaft highlights the importance of fatigue testing

5. Future development trends

With the upgrade of smart manufacturing, testing machines are moving towardsIntelligent(AI predicts crack paths),Efficiency(Multi-axis simultaneous testing) direction development. The global market size will reach US$1.2 billion in 2023, with a compound annual growth rate of 6.5%.

Conclusion

The crankshaft bending fatigue testing machine is a key equipment to ensure the reliability of the power system, and its technological upgrades will continue to respond to the industrial field's need to explore the ultimate performance of materials.
