Abstract EN
In recent years, hydropneumatic suspension (HPS) has come into widespread use for improving the ride comfort and handling of mining dump trucks and off-road vehicles.
Therefore, it is critical to improve the mathematical modeling accuracy to enhance the design and control efficiency and accuracy of HPS.
This paper aims to propose a model for improving the modeling precision by considering the effect of different factors on HPS characteristics.
A computational fluid dynamic (CFD) model of a HPS was developed, and the volume of fluid (VOF) method was used for the transient calculations in order to simulate the fluid dynamic characteristics and determine the damping and stiffness forces of HPS.
The effect of temperature, oil viscosity, nitrogen dissolution rate, and suspension vibration speed on the nonlinear characteristics of HPS was investigated.
A limited number of simulation sample points were designed based on the variation ranges of the above factors using the design of experiment (DOE) method.
The corresponding damping and stiffness force of each sample point were calculated by CFD simulation.
The obtained simulation data were utilized for the fitting of a Kriging model.
The results demonstrated that the Kriging model can provide high accuracy, with a prediction error lower than 5%.
The proposed modeling method of the HPS nonlinear characteristics is highly efficient, accurate, and faster than traditional methods.
