Study on Double-Drum Roller Maximum Braking Deceleration
Reducing start and stop time is important in enhancing productivity of double roller and compact quality of asphalt pavement, but it is difficult in confirming the max braking deceleration or starting acceleration of double-drum roller. Dynamic analysis is used and a mathematic model of double roller is established. Based on the model, the factors which affect the max braking deceleration is studied, such as braking force from hydraulic travel system, the adhesive force from ground, the inertia force from machine itself. And the max braking deceleration equation is obtained which consider the entire factors. The result indicates that drum inertia affects the max braking deceleration of double drum roller notable, and should be taken into account during design procedure and control program.
