The driving theory and the dynamic characteristics of small radius steering, medium radius steering and big radius steering is analyzed, and the simulation model is established under Matlab/Simulink. Then the track bulldozers steering performance of the three sheerings is simulated. The results show that, at different steering modes, the running states of the two sides driving motors are not the same, and the track driving forces of the two sides vary widely. The track driving force is great in the small radius steering model, while small in the medium and big radius steering models. The simulation results lay the foundation for dual-motor drive track bulldozers steering performance matching.

Aiming at the complexity of mechanical devices and the polytrope of operating conditions for marine propulsion plant, the modeling and simulation of propeller and dull system are investigated based on MATLAB/Simulink. The simulation model of propeller and dull system is constructed in which the Chebyshev fit expression across four quadrants is given for the propeller. So it becomes practical to express static and dynamic properties of propeller and dull system. A luxury cruises fitted on two engines and two fixed pitch propellers is considered to perform simulation tests. The actual navigation conditions of marine propulsion plant, including starting, parking and reversing etc, are taken into account. The simulation results analysis illustrates the correctness and validity of modeling and simulation for propeller and dull system. Thus provides a new method for the optimization and design of marine propulsion plant.

As one form in power-by-wire actuation system, the Electro backup hydraulic actuation system (EBHAs) has broad application prospects in the aviation field. In this paper, a numerical simulation model of the system performance for EBHAs is established. Based on the detailed description of its working principle, the mathematical models of EBHAs and its subsystems, as well as numerical model in the Matlab / Simulink environment are established, and a larger number of numerical simulations are carried out, which contain the normal working mode and the backup working mode. Furthermore, numerical simulation results are compared and analyzed with those results of experimental, which further verified the system simulation model established in this paper. It can be concluded from the results that the dynamic response of the system can meet the requirements of the design, no matter the normal or backup working modes. And the simulation results of the system sweep frequency are basically consistent with the test results, and the error is less than 10%. It is clear that the simulation model presented in this paper can accurately describe the system characteristics of EBHAs, which is useful to the design of EBHAs system.
