Analysis And Research On The Energy-saving Mechanism Of Balance Of Impact Roller

In the construction of infrastructure, Impact Roller plays a role for which other compaction equipments are not a substitute, except it does not full use of energy in the workplace caused by waste of energy, also exists the convex surface of the material that make tractor bump, Driver's extreme working conditions and has not been widely applied etc. But balance of impact roller basically solved the Impact Roller's main problems.In allusion to the issue of mechanical energy-saving, In this paper, "On the basis of the constant potential energy for the vibration and impact machine energy-saving designed principles " as the basis,after analyzing the constants and variables total potential energy of the system, it was verify that: in the design of mechanical systems, so as long as the total system potential energy for constant or tend to the smallest envelope, the system will reduce power consumption. At the same time, In mechanical design, if the system of kinetic energy in the smallest changes, which were very helpful for machines' energy-saving,after that educing the principle of mechanical energy-saving designing based on potential energy.In this study, taking the triangular-shaped impact roller, with its center of mass movement to establish the equations of motion,and draw its potential energy curve; Summed up the calculation formula of moment of inertia about the impact roller of wheel, At the same time, application of modern three-dimensional design software to work out the relatively accurate moment of inertia about the rotation axis of center of mass ,which provide the foundation for dynamic analysis;Application of Lagrange's equation to dynamic analysis the impact roller, and using of MATLAB for the numerical simulation, Come to the relationship between its power consumption and the time changes, It concluded the essence of the problem with a serious waste of energy is the cyclical mutation of potential energy;Based on 'the energy saving principle' , According to the specificity of the impact roller,and designed of balance of impact roller;Based on the above theory, with MATLAB to optimize the potential energy curve, obtained the scope of the best phase angle; In accordance with the changes in angular velocity to study the changes of the center distance,and the application of mapping method to determine the center distance of balance of impact roller; Argued that:the reason of energy-saving of balance of impact roller were among the system potential energy and kinetic energy in the smallest the changes and the road surface roughness. Through the model test and prototype testing, to draw the principle of potential energy saving had a good energy-saving effect, and which was correct.Through theoretical analysis,design and preliminary experimental test: in the design of machinery that must be met in addition to energy conservation principle, it was also come to energy-saving technologies which demanded traction at the maximum in the course of the entire work system and system kinetic energy in the smallest range of changes.
