- Articulated steering system is widely used in engineering vehicles due to its high mobility and low steering radius. The design parameters have a vital impact on the selection of the steering system assemblies, such as the operation stroke, pressure, and force of the hydraulic cylinders during the steering process, which will affect the system weight. The energy consumption is also relevant to the geometry parameters. According to the kinetic analysis of the steering system and dynamic analysis of the steering process, the kinetic model of an engineering vehicle steering system is established, and the power needed to boost it is calculated and validated by the field test result. The influence of the factors is analyzed based on this model. To lower the system weight and needed pressure, the multi-objective particle swarm optimization method is initiated to optimize the geometry parameter of the articulated steering system. After optimization, the weight of the system decreased by 0.61kg and the maximum force and pressure are decreased by 9.47% and 9.54% respectively.
