Authors | |
Abstract | Reducing start and stop time without destroying the pavement surface is important in enhancing productivity of double-drum roller and compact quality of asphalt pavement, but it is difficult in confirming the maximum brake deceleration or start acceleration of double-drum roller. Dynamic analysis is used in studying these questions, and a mathematic model of double-drum roller is established, based on the model, the factors which will affect the maximum brake deceleration of double-drum roller is studied, such as brake force from travel hydraulic travel system, the adhesive force from compacted ground, the inertia force of drums and double-drum roller itself. And the max brake deceleration equation is obtained which consider all these factors. It indicates that drum inertia affects the max brake deceleration of double-drum roller notable, and should be taken into account during design procedure and control program. At last a maximum deceleration control method based on slip control and classic PID algorithm is advised. |
