Optimization Research On One-shaft Auto-walk Rolling And Taping Machine

It is obvious that small-sized compact machine has been more and more popular since ten years ago. Because of its high mobility and easy control, being auxiliary facility in the great-scale construction engineering, the small-sized compact machine has been indispensable in the small engineering and widely used in pipe laying engineering of water, gas and electrical equipment.But seeing from the current situation in our country, there is almost none mature product or manufacture company on small-sized compact machine of our own. So it is emergant to develop the machine with light weight, small volume, well-knit structure, good compacting function, high function-price ratio and our own intellectual property right.After years research, our country's scientific research institution has developed some models of small-sized compact machine, such as hand-holding vibration roller, circled vibrating compactor, auto-walking vibration roller. Learning from these models, it's difficult to integrally solve the problems of small compact machine with well-knit structure, stable walking speed and low costs.Based on the previous work of other people, this thesis establishes the kinematics differential equations of the old prototype of auto-walk vibration rolling and taping machine, then solves the equations through sensible simplification and gets the factors which effect the machine's auto-walking speed obviously; Based on these factors, new model of the auto-walk vibration rolling and taping machine is set up; utilizing the powerful ADAMS, we gets its optimal structural and moving parameters and the fastest walking speed through kinematical and dynamical emulating and optimizing under kinds of different conditions. At last, by contrasting the emulation results with the practical testsof the old prototype of auto-walk vibration rolling and taping machine, I verify the sensibility of ADAMS optimizing results of it and realize the idea to largely promote the auto-walking speed and stable work of the machine and effectively simplify the model.
