In order to improve fuel economy, the number of gears in the hydraulic automatic transmission of heavy-duty mining trucks is continuously increasing. Compared with single-transition shifts, double-transition shifts can optimize the structure of multi-speed transmissions, but the difficulty of control will also increase. In this paper, a dynamic model of a 6 + 2 speed automatic transmission and vehicle powertrain system are built based on the Lagrange method, and the dynamic analysis of the two sets of clutches that make up the double-transition shift are carried out. Since a simulation model of the double-transition shift process is built-in MATLAB/Simulink, the shift jerk and clutch energy loss are used as multi-objective, and the genetic algorithm is used to optimize the simulation. Five strategies for the overlapping time of the clutches are proposed, and simulation experiments and Pareto optimal analysis are carried out, respectively. The simulation results show that the non-overlapping of the two sets of clutch inertia phases in the double-transition shift can effectively reduce the shift jerk. The overlapping of the torque phase and the inertia phase of the other clutch set can control the clutch energy loss at a low level due to using less shift time.

The Relationship

China's export-led growth is rooted in China's double transition of demographic transition and structural change from industrialization. Accession to the WTO has allowed China to fully integrate into the world system and capture the gains of its comparative advantage in abundant labor supply. Structural change has a dampening effect on the Balassa–Samuelson effect so as to sustain China's competiveness in the world market. The double transition will take 10 to 15 years to finish; in this time period, China will likely continue its fast export-led growth. Along the way, export-led growth has also created serious structural imbalances highlighted by underutilized savings, slow growth of residential income and domestic consumption, and a heavy reliance on investment. This linkage requires new thinking when global imbalances are to be tackled.
