Description

technical field [0001] The invention belongs to the technical field of vehicle passability evaluation, and relates to an in-situ test simulation device for wheeled vehicle passability. Background technique [0002] Vehicle passability generally refers to the ability of vehicles to drive on uneven roads and soft soils, and generally refers to the support passability of the road surface. The main task of vehicle bearing passability research is to use theoretical analysis and experimental methods to explore the working characteristics and load conditions of various vehicles under different soil conditions, so as to improve vehicle performance, and according to soil characteristics, the relationship between load and vehicle parameters, Develop mathematical models and equations to determine vehicle design parameters and ideal design solutions. The ground factors that affect the vehicle passability mainly include the pressure-bearing characteristics, shear characteristics and bea...
