Mechanical press is a widely used engineering smiting device for materialsprocessing pressure. With the rapid development of heavy industry, improve thekinematics performance of the mechanical press operating mechanism and laborproductivity, is the basic requirement of modern manufacturing plastic processing. Inthis paper, three kinds of multi-link press to carry on the research, the main researchwork and achievements are as follows:(1)This paper is based on the analysis of multi-link press, by means of numericalanalysis and synthesis method, established the kinematics model of multi-linkmechanisms, and provides the mathematical foundation for simulation and optimizationof mechanical press.(2)Based on virtual prototyping technology, three-dimensional models ofmulti-link mechanism in ADAMS are established, simulated respectively six-barpressing mechanism, double crank seven-bar and eight-bar machine, and kinematicssimulation, parameterized design variables, design study and optimization design, thediscrete method respectively in three kinds of mechanism kinematics optimization,improve performance of mechanical press.(3)Proposed a modeling method of double crank seven-bar mechanism to handle asflexible body, by simulation comparison, replacing the rigid body with flexible bodycan achieve a more realistic simulation of the dynamic behavior of mechanical exercise.In this paper, analysis and optimization of multi-link press are only for singletarget optimization, without taking into account other factors outside possibility.Conditions are ideal. The future will continue to further optimize. |
