Research On High - Speed And High - Speed Driving Technology

Fast and continuous high impact driving technology is used to simulate multiple penetrations for fuse in the experimental environment, with its working requirements of speediness, continuousness, and high impact.In this paper, the fast and continuous high impact driving technology was research object. The drive mode of hydraulic and mechanical spring was set in parallel, and then the system design scheme of control and acquisition circuit was further supported. First, the two key technologies of the hydraulic and mechanical spring impact were studied in view of the significance of driving technology. The mathematical formula of hydraulic rapid motion and high speed impact of mechanical spring motion were derived. Thus factors influence the system motion were analyzed which provides theoretical basis for the simulation verification and prototype design. Secondly, the AMESim and ADAMS simulation software were used to establish the simulation model of hydraulic and spring collision, and the effect of several key factors on the movement of the hydraulic system and the effectiveness of spring on realizing the high speed collision were analyzed by simulation. Then, on basis of the theoretical derivation and simulation result, the driving experimental device through AMEsim, Solidworks, Altium designer software was designed, which was composed of accumulator fast hydraulic circuit, mechanical spring collision mechanism, control and collection circuit. Finally, the experimental prototype was tested. The motion displacement curve of hydraulic system when 6-12Mpa pressure was applied and impact acceleration curve with spring stiffness of 125000N/m and time interval of 20ms,25 ms,30 ms,and 35 ms are obtained. The experimental results shown that the device designed can meet the desired requirements.
