TL;DR
This paper introduces a new double-track rail system for transporting heavy agricultural machinery in hilly regions of southern China, improving stability and efficiency.
Contribution
The novel double-track rail system and its dynamic performance analysis in hilly terrains are presented.
Findings
The rail system's stress–strain distribution was analyzed under a 750 kg load using resistance strain gauges.
The first 20 natural modes of the double-track rail were identified using the Eigensystem Realization Algorithm.
Comparative analysis showed the rail's vibration characteristics under constrained and actual boundary conditions.
Abstract
To address the limitations of conventional single-track rail systems in challenging hilly and mountainous terrains, which are ill-suited for transporting heavy agricultural machinery, there is a critical need to develop a specialized the double-track rail transportation system optimized for orchard equipment. Recognizing this requirement, our research team designed and implemented a double-track rail transportation system. In this innovative system, the rail functions as the pivotal component, with its structural properties significantly impacting the machine’s overall stability and operational performance. In this study, resistance strain gauges were employed to analyze the stress–strain distribution of the track under a full load of 750 kg, a critical factor in the system’s design. To further investigate the structural performance of the double-track rail, the impact hammer method was…
