Abstract
The gearbox used in the tractor and double trailer combination has more gears, which is complicated and not easy to design. In order to improve the overall vehicle power performance, this paper jointly builds a virtual simulation platform with MATLAB and TruckSim and carries out transmission optimization design based on the Monte Carlo method. The design combines the original scheme of an 18-speed gearbox and the two-parameter optimal power shifting strategy to form a new scheme and a new shifting strategy by randomly casting points in the region. The study shows that the iterative convergence curve of the Monte Carlo design for transmission gears is continuously increasing; for the fixed driver shifting strategy, the power performance of the manual transmission is effectively improved after optimization, and the improvement effect is more significant in the middle and high speed; the power performance of the vehicle generally decreases after the change of the two-parameter optimal power shifting strategy; the improvement effect of the automatic transmission is relatively limited after optimization on the basis of the original scheme. This kind of virtual simulation platform can help the teaching and practice of the content related to powertrain design in vehicle engineering.
