A recent trend in the development of off-highway construction equipment, such as excavators, is to use a system model for model-based system design in a virtual environment. Also, control system design for advanced excavation systems, such as automatic excavators and hybrid excavators, requires system models in order to design and simulate the control systems. Therefore, modeling of an excavator is an important first step toward the development of advanced excavators. This paper reviews results of recent studies on the modeling of mechanical and hydraulic subsystems for the simulation, design, and control development of excavator systems. Kinematic and dynamic modeling efforts are reviewed first. Then, various approaches in the hydraulic system modeling are presented.

In order to analyze the dynamic characteristics of the concrete pump closed type hydraulic system in the process of pumping, we add two speed sensors and power units in the system, to achieve the dynamic loading of the pumping load by judging the main oil cylinder speed. We also establish the concrete pump closed type hydraulic system model for the dynamic simulation. The results show that in the process of pumping, pumping pressure keeps constant value and no pressure impact. Meanwhile the piston displacement linearity increases or decreases and the piston velocity keep the constant value.

In order to meet the requirement of fiber splicing, the problem of low efficiency and manual operation is adopted. The device is designed and fabricated to meet the convenience and convenience of splicing and equipping in optical fber production. The simulation design and control system design of SolidEdge are discussed. At present, there isno such device in the market, and it has certain value in optical fber equipment.
