Embodiment Construction

[0025] figure 1 It is a block diagram of the system structure of the present invention. First, it is the physical system of the real pump truck boom. The model library of each part constructed after dismantling is mainly the model library of the mechanical arm, control, hydraulic pressure, and sensor. The two models built through these model libraries are System-level model library, the difference between these two model libraries is the different folding methods of the pump truck boom, which are R-type folding method and Z-type folding method. The R-type folding method is complex and takes up little space, while the Z-type folding method is simple but takes up a lot of space. The former is mostly used in multi-arm systems, while the latter is mostly used in systems with fewer arms. After the system-level model is built, it is the simulation control, which mainly includes algorithm setting, control time setting, parameter setting, etc. The last part is the simulation result,...

Abstract

The invention discloses a Modelica language based design method of a system for stimulating a cantilever crane of a concrete pump truck. The method comprises the following steps of: detaching a real physical model according to a sequence of a cantilever crane main body, functional subsystems of the cantilever crane, and components of the cantilever crane; establishing each model library according to a sequence of a component module library, a subsystem module library and a system module library, establishing a parameterized interface of each module based on parameterized modeling, and transferring physical and mathematical equations through parameters between the interfaces; encapsulating a model and providing a user parameter setting window, wherein the same model library has a common interface and different model libraries are connected by an element comprising the common interface shared by the different model libraries, so that parameter transfer between models in different fields is ensured and a complicated pump truck cantilever crane model cam be built. The Modelica language based design method of the system for stimulating the cantilever crane of the concrete pump truck has the characteristics of modularization, layering, standardization and parameterization; stimulating modules are interoperable and can be reused; and through an open modeling concept, different components can be added in the using process.

Description

technical field [0001] The invention relates to the field of computer simulation, in particular to a design method of a concrete pump truck arm frame simulation system in multiple fields such as hydraulic pressure, machinery, control, and electronics. Background technique [0002] In the field of booms of concrete pump trucks, computer simulation can take advantage of the characteristics of less investment and quick results, and quickly obtain several different design schemes with less investment. Its design is often nonlinear and interdependent. This requires comprehensive consideration of the boom system of the pump truck in the process of modeling and simulation, and the establishment of a complete and perfect model as much as possible. Professor Zhang Guozhong from Shenyang University introduced the CPCWD software system for the overall design of concrete pump trucks developed by him in the article "Research on the Concrete Pump Truck Arm Frame Distribution Mechanism an...
