Abstract

To address the challenges of testing traction performance parameters of agricultural tires under varying soil types, tire specifications, and operational conditions, a dedicated test platform was developed to improve efficiency and reduce workload. The system includes a hydraulic drive with adjustable torque and speed, and a data acquisition module. Key components were selected based on design requirements and the frame was modeled and analyzed using ANSYS for both stress strain behavior and sixth-order modal characteristics, confirming structural integrity and absence of resonance. Field experiments were conducted using a 12.4-24 agricultural tire in accordance with the Chinese national standard GB/T 14828-2003, under three test surfaces: asphalt, withered grass field, and tilled soil. Results indicate that the developed equipment performs reliably through these conditions, demonstrating good stability and accurate data acquisition. The system's main specifications include external dimensions of 3155 mm x 1750 mm x 1385 mm, a total mass of 835.5 kg (1308.5 kg fully loaded), a variable speed range of 0-12 km/h, and a maximum driving torque exceeding 1000 N·m. These findings support the effectiveness and practical applicability of the device in agricultural tire traction performance testing.
