| Since the construction of hydraulic excavator efficiency, quality, multi-purpose, and other aspects, as has long been an important earthwork machinery has been widely used. As recent social development, and market conditions change, the community-wide hydraulic small, mini-excavators have a new demand, manufacturing production has become more vigorous development.In accordance with the usual classification, small hydraulic excavator is the power system, hydraulic system, working devices, rotary devices, operating devices, and electrical systems and other components. In addition to the general common hydraulic excavator, because of its cost and size constraints, some small excavators have their own characteristics, features in many of the most critical one is that the small single-Doo hydraulic backhoe excavators are often subject to Manufacturing costs and the restrictions can not be equipped with more advanced electronic control devices, making it the performance to a greater extent, dependent on the hydraulic system of mechanical devices such as the design level; In addition, relative to large and medium-sized excavators also on the system a higher degree of integration requirementsPapers consider two excavators working device, first, excavators working device itself. Work can be understood as robotics unit in the operation of the robot, the use of Newton - Euler's formula dynamics modeling analysis, this could be boom, Doo-working equipment such as the internal structure of the introduction of performance parameters simulation design, use it can be installed in the work of excavators digging under steady-state distribution of the changes. The second is from the focus on analysis of the hydraulic system of control device performance. This paper LUDV analysis of the impact of the work flow system of distribution of the simulation analysis, briefly discussed the load of traffic load distribution and a single linear flow control the problem.
