Design of electric drive system for construction machinery chassis

Abstract The main advantages of the construction machinery chassis are high energy consumption, a large number of consumption and emissions, so the research of energy saving in the current energy and environmental conditions is very important practical significance. This paper analysis the object of study is representative of mechanical engineering -- chassis of engineering machinery, and chassis of engineering machinery work of energy consumption and emissions of quality is mainly affected by the influence the dynamic system, including its structure, parameters and control methods etc., so the engineering machinery chassis energy saving consumption mainly is to study the design of the power system.

The task is to study and design of engineering machinery chassis power drive system and electric drive technology is an important trend in the development of construction machinery industry, the key technology mainly including electric drive control system, the battery management system and power source. Engineering machinery chassis drive system is in today's world of electric vehicle research and development and industrialization of a new engineering machinery chassis development direction is synchronized, because of the widely used the ideal control characteristics, by the academic and engineering circles widespread attention. Four wheel independent drive technology can make the construction machinery chassis electronic, greatly improve the performance of the construction machinery chassis, so that the power driven system of articulated engineering machinery chassis is more competitive.
