Simulation Evaluation of Ultra-high Value of Special Ramp for Trucks

In order to verify and revise the rationality of the application of the ultra-high value (maximum value and recommended value) specified in the specification in the special ramp of truck, it analyzes and compares the advantages and disadvantages of the calculation models of the point mass-rigid body (PMR) and the point mass-suspension (PMS), and proposes the ultra-superhigh calculation model suitable for the special ramp of trucks. According to the Japanese code, the distribution model of the ultra-high and transverse force coefficient of the special ramp for trucks is established and the recommended value is put forward. Trucksim simulation software is used to verify the rationality of the ultra-high values proposed according to the new mechanical calculation model and distribution model. The results show that according to the new mechanical model and distribution model, the new minimum radius of special ramp for trucks is more reasonable than the standard value.
