The Research on Instant Contact Deformation of Round Link Chain Based on Symmetric Penalty Function Method
In order to analyze deformation and stress state of round link chain which it is generated by instant impact for sudden loading between the chains during the working condition,the method of symmetric penalty function was adopted to analyze contact between round link chains; and the timite element software ANSYS LS-DYNA was further used to carry on nonlinear contact analysis,the displacement curves,the stress and deformation with time were gained during the process of impact by simulating the process of the instant impact of chains.The results show that it is circular to the contact area of round link chains and it is the main reasons of damage that the greater stress and deformation of impact is caused when time lasts 0.05s through theoretical analysis and finite element analysis software.The theory equations of load conditions and the method of finite elements can provide a theoretical basis and simulation methods for analyzing the round link chain driving in a variety of different working conditions under the conditions of impact.
