Center Of Pressure, Bulldoze Traction, and Resistance Force
Abstract
Because of effect outside force particular resistance force the center of caterpillar pressure to be moved from central point of caterpillar, it changes bulldoze traction-adhesive particularity. It is the best if the center of pressure is to be move in permissible limit. It may be done by design sensible structure of working organ and bulldoze, choice logical working regime or use active work. One of the active work to decrease resistance force, to limit the center of pressure to move away is using compressed air to lubricate the blade order to decrease force of friction of soil shaving moving on board surface. The move of the center of pressure depends on effect of decrease resistance force and bulldozes structure parameters. This article presents method to define resistance force of work based on theory about limit state of desultory environment and algorithm to specify bulldoze structure parameters in propose to guarantee the center of pressure move in permissible limit and increase bulldoze traction.
