Abstract:
For the complex structure of a hybrid mode aerial working mechanism, a three dimensional contact element method is proposed for its strength analysis. In order to validate the precision of this method and to analyze the influence factors of global stress distributions, strength analysis of a simply supported beam was adopted firstly by this method, and then compared with traditional degrees of freedom(DOFs)coupling, an interface element method and theoretical solutions. The results indicate that the contact element method is more precise; frictional coefficient and stiffness factors have only a little influence on global stress distributions, the maximum tolerance is less than 7%, and the effect of penetration tolerance factors can be ignored. Finally the finite element model of the whole mechanism is set up by the contact element method involving frictions, where solid elements and spring elements are integrated to build the model of a hydraulic system. Compared with the test results the tolerance of analysis results is lower than 15%, which proves that the contact element method is precise and can be widely applied in practice.
