[CN 201610663402.9] A rod system modeling method for eight-link mechanical press
[CN 201610663402.9] An eight-link mechanical press rod system modeling method Title: An eight-link mechanical press rod system modeling method Application Number: CN 201610663402.9 Applicant: Hefei University of Technology Application Date: 2016-8-12 Patent Type: Invention Application The invention discloses an eight-link mechanical press rod system modeling method, which is characterized by: setting the parameters of each rod system to be obtained for the eight-link rod system as variables, two objective functions related to variables are established. The constraint conditions to be met by each variable are proposed, and the fitness function of the variables is established under the conditions of meeting the constraint conditions and not meeting the constraint conditions respectively. Then the NSGA II algorithm is used to solve the values of the variables. The value range of each variable is given in the solution process, and the satisfactory solution of the variable is assigned to the rod system parameters to complete the rod system modeling. The invention can determine the parameters of the rod system for the known eight-link press design requirements, and facilitate the development of presses with different strokes.
