Along with the rapid development of construction, aerial work platform, as  a kind of tall buildings cleaning, maintenance and adornment machinery has been  widely used. Aerial work platform compared with traditional mechanical safety,  high efficiency, strong adaptability etc many advantages, its overall and local  stability study to ensure construction safety, reducing safety accidents have  very important significance.

First, the overall use of moment method overturning stability, using MATLAB  software to draw the stability coefficient curve, obtained the mechanical  stability of the overall conclusions of overturning; on the frame so rigid  assumptions, calculations leg reaction force, come within the scope of work four  point support and the three supporting both cases;

Followed by use of ANSYS software validation by comparing the displacement  of the overall stability of the leg;

The final specification were used finite element method algorithm and  section 4 of the local stability of the arm, found that partial plastic  instability in the webs of first arm section, but the more conservative  specification algorithm; on the whole do telescopic eigenvalue buckling and  nonlinear buckling analysis, obtained the first part of the tank failure webs  connecting hinge points of cylinder.

The nonlinear buckling analysis is sufficient to simulate the actual  situation, draw telescopic arm section 4 and the overall buckling load when the  hanging baskets were 12058N, and 10126N.
