Abstract


Aerial work platform is used to operating personnel and equipment shipped to the height specified operating special vehicles , should have a higher stability, security and reliability . Works of aerial work platforms and working bodies GTZZ21 type telescopic boom aerial work platforms work agencies as the research object , the establishment of a working body dynamics model based on virtual prototyping technology . Co-simulation method based on the finite element and multi-body dynamics and modal synthesis method based on the proposed establishment of rigid-flexible coupling model of aerial work platforms , and the model is a dynamic simulation study . The following content characteristics of working bodies , the use of three-dimensional modeling software Pro / E to establish the working bodies of the CAD model , and the model is appropriate simplification . Jointly by Pro / E software and dynamics analysis software ADAMS , rigid body dynamics model of aerial work platforms , and a simulation analysis of the operating conditions . Dynamics model simulation results and theoretical analysis of the data , verify the correctness and feasibility of the model . 3, according to the typical operating conditions of the working arm of the aerial work platform design feasible experimental test the typical conditions luffing cylinder displacement data and the strain data of the measuring points of the working arm , and its processing and analysis for the further simulation analysis and made the necessary preparations . 4 , using the finite element analysis software ANSYS work arm modal neutral file is generated in the modal synthesis method based on the establishment of a system of rigid-flexible coupling model . System dynamics simulation to obtain the corresponding measured strain data points are compared with the experimental results verify the practicality and effectiveness of the simulation model . This paper set design and theoretical basis for the design and further study of the dynamic model of aerial work platforms , papers involving research methods can provide a reference for future research
