This research article investigates the nonlinear characteristics of a three-axle rigid mine car equipped with a balanced hydro-pneumatic suspension system and the influential factors affecting these characteristics. Through extensive simulation calculations, the performance of the suspension system was assessed under obstacle-crossing trench conditions. A comprehensive multi-signal data acquisition and analysis system was developed to synchronously collect critical parameters such as pressure displacement within the oil and gas suspension cylinder and stress and strain data from the supporting structure. The resulting time-domain curves captured variations in these parameters during testing at speeds of 10 km/h and 25 km/h on flat surfaces and obstacles with specified dimensions. The interaction between the suspension cylinder’s loading capacity and operational characteristics was evaluated, revealing a significant inverse relationship between pressure and displacement, particularly within the front suspension system. Stress analysis indicated high stress concentrations at critical points during obstacle crossings, suggesting areas for potential performance improvements. Additionally, findings demonstrated that maximum stress in the cylinder support occurs during dynamic loading conditions, highlighting the need for reinforced designs under such scenarios. Collectively, this comprehensive analysis lays the groundwork for enhancing the robustness of oil and gas suspension systems in mining vehicles, contributing valuable insights for their future development.
