Theoretical and experimental considerations regarding to functioning of a combat vehicle shutter’s hydraulic actuation system

Abstract

Abstract:The paper proposes a theoretical analysis of kinematic and dynamic performances of several elements in the composition of a combat vehicle shutter's hydraulic system, using LMS AMESim, specialized CAE software. System descriptionThe project refers to a controlled opening system for a combat vehicle shutters. These shutters are disposed on the ceiling housing armor. Their opening is done with hydraulic cylinders, one for each one.Hydraulic installation scheme was carried out in order to meet the requirements imposed in the development operational project. These requirements are: The maximum opening/closing time to not exceed 15 second;  The system must be provided with a hydraulic discharge element, for manual manipulating in case of damage;  Hydraulic pump powered at 24 V.  The mass of a shutter to not exceed 150 kg The designed actuating system of shutters is a hydraulic system with electrical command. The electricity used to power the system's pump is obtained from additional installed electric generator inside of vehicle or from vehicle batteries.The system's command is realized from an electrical panel. In case of damage, this system allows manual operation of the shutters.The hydraulic system diagram of shutter's actuating (shown in figure 1) has the following components:
