Selection method of tracked vehicle damping characteristics

Bauman Moscow State Technical University, Moscow, 105005, Russia

At present, due to the increase in the caterpillar machines power-to-weight ratio, when

the technologies for manufacturing highly-engineered engines are known and widely

used, the machine average speed following the traction capabilities limitations has in-

creased significantly. Therefore, the motion regime along periodic irregularities is possi-

ble, with the caterpillar being completely detached from the supporting surface. This

motion type leads to constant incidence of the car from a certain height and frequent sus-

pension breakdown, since the suspension system (SP) is selected according to other crite-

ria. The article considers a method for selecting a damping characteristic that provides

the maximum energy capacity while providing a given acceleration level in the driver

place. The article shows simulation results, and confirms that the powerful forward

damping introduction allows us to suppress the oscillations.

Keywords:

caterpillar machines, torsion suspension, pneumohydraulic suspension, sus-

pension system, smooth running, damping
