Study on Automatic Spray of Distribution Boom System of

The concrete pump car was modeled in 3DMAX, then it was imported into the virtual scene. The model can simulate the process of concrete pouring, through which search algorithm can be tested.

Modeling and Analysis of Truck Mounted Concrete Pump Boom

By far there is lack of research on different working conditions between rigid and flexible dynamics of truck mounted concrete pump booms. First a 3D model has been established by using virtual prototyping technology of a 37 m long boom in Pro/Engineering software. Then the rigid body simulation model has been built. Next modal superimposition method is adopted to change the 4 rigid body booms

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. Qing Yun Liu, Wei Wang the research indicates that the 3-D finite element model is an efficient and accurate method to calculate

Research on rigid–flexible coupling dynamic

Apr 06, 2015 · Three dynamic models of boom system in concrete pump truck were established in this article. The multi-rigid-body model was built at first. Then, the modal reduction method is adopted to build the rigid–flexible coupling model. At last, spring–damper systems were equivalent to the hydraulic cylinders by virtual spring–damper method.
