Possessing the merits of good solidness, high security and excellent  reliability, the aerial work Platform is a kind of special vehicle which can  lift operators and working equipment up to the specified altitude. Based on  virtual prototyping technology, dynamics models are established against the  background of the work unit of Runshare telescopic arm aerial work platform.  Besides, on the foundation of the modal synthesis method, a rigid-flexible  coupling model of the Runshare aerial work platform is created by the method of  finite element and multi-body dynamics joint simulation.

Runshare’s research focus on the following points:

1.Characteristics for the working body, the use of three一dimensional  modeling Software Pro / E CAD model to establish a working body, and appropriate  to simplify the model.

2.By Pro/E software and dynamic analysis software ADAMS joint, the Establishment of a high-altitude Platform for rigid body dynamic model, and  its simulation analysis of a certain working conditions. Through the dynamic  model simulation results and theoretical analysis and comparison of data to  verify the Correctness and feasibility of the model.

3.Designing a feasible experiment Plan to test and gather the displacement  data of Amplitude Cylinder and the strain data of the measurement Point on the  working arm of Platform in the typical condition, and afterwards, analyzing and  handling those prepare for the simulation and analysis of Runshare aerial work  platform.

4.The finite element analysis software ANSYS will work arm modal neutral  file generated in the modal synthesis method, based on the established system of  flexible coupling models. The system dynamics simulation, the strain measuring  point corresponding to the data, compared with the experimental results verify  the feasibility and effectiveness of the simulation model.

In summary, the work Provides design foundation and theory gist for  Runshare’s further researches about high-low Pressure rocket launch system, and  the research methods provides reference for further research.
