Bolted joint loosening in agricultural machinery is a major safety risk due to harsh conditions. Current monitoring methods are insufficient, necessitating advanced, cost-effective online systems for improved reliability.
Area of Science:
- Agricultural Engineering
- Structural Health Monitoring
- Mechanical Reliability
Background:
- Bolted joints are critical for agricultural machinery structural integrity.
- Loosening is a prevalent failure mode exacerbated by vibration, impact, and corrosion.
- Inadequate traditional inspections lead to failures, reduced efficiency, and safety hazards.
Purpose of the Study:
- To comprehensively review bolted joint reliability challenges in agricultural machinery.
- To evaluate conventional and modern detection methods for bolt loosening.
- To identify deficiencies and propose future research for agricultural monitoring systems.
Main Methods:
- Literature review of bolted joint failure modes and environmental impacts.
- Analysis of conventional detection techniques for joint integrity.
- Classification and assessment of modern monitoring technologies (vibration, acoustic, direct, vision-based).
- Evaluation of techno-economic feasibility and limitations in agricultural applications.
Main Results:
- Current bolt loosening surveillance technologies show significant deficiencies for agricultural machinery.
- Existing methods are often inadequate for harsh agricultural environments.
- There is a critical need for specialized, reliable, and affordable online monitoring solutions.
Conclusions:
- Existing bolt loosening monitoring technologies are insufficient for agricultural machinery.
- Developing tailored, cost-effective online systems is essential for enhancing machinery reliability and safety.
- Future research should focus on intelligent and robust structural monitoring solutions for agriculture.
