Along with the development of construction industry in our country, high-rise buildings by leaps and bounds.Aerial work platform instead of traditional scaffold has been recognized. And be used widely. Aerial work platform are widely used in construction of exterior decoration, cleaning and maintenance etc homework occasion at the some time it install mobile and manipulation convenient, so it provided convenience for construction.This paper firstly take the aerial work hanging basket suspension mechanism as an example, when it working in pre-tightening and inherit maximu load situation, MTR wire rope strength coefficient and the arm strength safety coefficients of the was derived, on this basis we do the finite element analysis for the suspension mechanism of aerial work platform, proposed the main form of suspension mechanism intensity failure, then we proposed some major measures to improve the intensity of suspension mechanism.Based on the design idea and technical route of finite element method, and mainly aimed at the load-bearing institutions of the ZLP500U suspended working platform. According to the basic principle of mechanics and mechanics we simplify the structure properly. Using the interface technology of ANSYS and CAD, established working platform model, and analyses the static structure strength and stiffness under the actual three under the conditions of platform truss structure, as a result the biggest stress and strain appear in the chassis of different respectively on the beam.Through research on the dynamic characteristics of the ZLP500U suspended working platform, validation the structure design of it is rationality, Using subspace modal extraction method we conduct modal analysis for the U suspended working platform, then get the form six order natural frequency and vibration mode, by the structural harmonic response analysis and transient dynamic analysis, get the vibration frequency and the displacement response maximum of the U suspended working platform dangerous node. Based on the structural dynamic analysis, it can guide the U suspended working platform’s further optimal design, and ensure its construction safety and stability. Based on the finite element analysis results, in order to reduce the weight of the working platform, taking the structural strength and rigidity as constraint conditions, we conduct optimal design on the working platform structure with first-order method, get optimized results, provides reliable according to reports for the structure improvement.
