Aerial work platform is a kind of aerial work engineering machinery and equipment, widely used in construction，municipalization，factories，gardens and other places，and mainly engaged in fire fighting， rescue and relief， construction installation and maintenance，etc. Along with the development of the urbanization process， the larger using domain and quantity of aerial work platform，the increasing of operation difficulty and the more complicated working environment，more advanced and reasonable aerial work platform are needed to be designed urgently in order to adapt to social development and meet the needs of economic development.
Focuses on GTBZ25 aerial work platform developed by Runshare., we took the method of collaborative design and 3D design in Pro/E has been used. In order to ensure the safety of operating personnel，stability as a key issue has been calculated in considering the tyre reaction. The results getting from co-simulation of main bearing hinge point in superstructure by ADAMS and MATLAB have been compared with traditional manual calculation results to ensure the rationality of the hinge point force. The stress and strain of main stress components ， such as boom ， rotary table and frame in prototype，have been analyzed in the finite element software Workbench. In addition，the stability of leveling oil cylinder，telescopic arm’s bundle cylinder and derricking cylinder in aerial work platform has been checked， while the major points of hinge pin have been selected and checked. In order to making more competitive products in the market, meeting the reasonable cost and reaching the expected design goal, the engine，hydraulic system and slewing mechanism have been calculated in type selection. Trial prototype meets the design goals and objectives after a series of experiments. At last，the third-party testing agency has been invited for prototype test，which qualified the test results provided a theoretical basis for the research and design of Runshare GTBZ series aerial working platform.
