Abstract

The advantages of shelter are high utilization, mobility, versatility and variety of modes of transport.It also can be convenient for maintenance and can provide unique advantages of the internal working conditions in harsh environments, especially in the important role of modern war can not be underestimated. In order to meet modern warfare, logistical equipment and supplies in a timely manner, easy to operate, high degree of mechanization and informationization requirements. Improve equipment, battlefield survivability to carry out the machine solution platform "developed an extremely important military and practical significance.

This article describes an extension of the commencement of the shelter system, select a structure suitable for complex terrain, and the use of hydraulic technology to control the commencement of the extended shelter and recover the system, according to the technical specifications of the extension tank to expand the system hydraulic system overall program design. And discuss and select the appropriate synchronization scheme, the control program designed hydraulic schematic and electrical control diagram. Finally, in accordance with the given institutional performance parameters and hydraulic performance parameters to component selection and calculation, to meet the requirements of indicators to be achieved in the cabin.

Keywords: shelter  Synchronous  electro-hydraulic control
