The direction of scientific research connected with increasing the efficiency of timber road transport by reducing energy losses in the hydraulic drive of the manipulator in the process of loading and unloading timber has been substantiated. The analysis of scientific works in the field of methods of recuperation of various types of energy in wheeled vehicles, recuperative devices and hydraulic drives, allowing to accumulate and usefully use the energy of compressed air. A perspective diagram of a recuperative hydraulic drive of a timber truck manipulator with a pneumatic system is proposed. The goal of the work is formulated, which is to develop mathematical and simulation models for the functioning of the proposed pneumatic system of a recuperative hydraulic drive for assessing the necessary indicators of its efficiency based on the revealed dependencies. Developed and investigated mathematical and on its basis simulation models of pneumatic system functioning. The dependences of the influence of time on the amount of compressed air, pressure and temperature in the pneumatic accumulator and pneumatic cavities of pneumatic cylinders are obtained.
