Analysis of properties on cargo constrained system of truck rollover based on MATLAB/simulink

This paper set up a system which was made of truck, cargo and constraint device. To model this system, the paper selected EQ_1156W_3 truck as the research object, and used two TD_50B as the cargo constraint device according to the mass of the cargo and the American standard. Used lateral acceleration as rollover index of vehicle-cargo-constraint system, and calculated the rollover threshold in order to evaluate the anti-rollover performance of the truck by fewer parameters, then got the relationship between the mass of cargo and rollover threshold. On the basis of analysis of rigid body vehicles, the influence of the tyre and suspension to truck rollover was considered, and the mathematical model of vehicle-cargo-constraint system was established. The analysis on cargo constrained system of truck rollover based on MATLAB/simulink was used.
