Simulation And Optimization Of A Certain Type Of Vehicle Artillery Hydraulic Support System

The vehicle-mounted howitzer is a new type of artillery developed in recent years. Theartillery and chassis shared power and control platformwhich makes the organic integrationof firepower and mobility.Vehicle-mounted howitzer has been got rid of the traditional model limitations. It combines the self-propelled artillery "self and towed artillery "simple" and find a better balance between the tactical performance and fitted out costproviding a more powerful fire support for the rapid mobility combat mode in the modern conditions. The chassis of the vehicle-mounted howitzer is relatively light, so that the emission stability has been greatly affected. Therefore, a stable performance and efficient transition support system is particularly necessary. This paper is focused on study of the vehicle-mounted howitzer hydraulic support system during expanded and collapsed process and the impact of the back seat on the hydraulic support system in the emission process, the main contents include as following:1. Modeling of vehicle-mounted howitzer hydraulic support system.The characteristics of a certain type of vehicle-mounted howitzer hydraulic support system have been analyzed. Two different models have been established using AMESim software based on the operational status of the system, simulating working process of the line into wartime and emission process, which lay the foundation for the next step hydraulic support system analysis and optimization.2. Simulation and analysis of vehicle-mounted howitzer hydraulic support system.Thesimulation and analysis of war conversion processof hydraulic support system have been carried out. The various influential factors for the hydraulic support system in the expandable and collapsible process have been simulated. The causes of the jacks and hoesis not synchronized during the expandable and collapsible process have been found. The hydraulic components dynamic curves of the instant impact force on the hydraulic components have been researched during the emission process by simulating the hydraulic support system during launch, and thecauses of soft leg phenomenonexisting in the emission process are analyzed, which provide the basis for the next step optimization scheme.3. Optimization design on the hydraulic circuit of the hydraulic support system.The optimization design on the hydraulic circuit of the hydraulic support system have been carried out, mainly for the optimization objectives of the expanding synchronization in line war conversion process and reducing the emission of the impact of destructivity and the hydraulic outrigger retraction caused by the emission of shock. The improvement and optimization have been achieved of the twoabove phenomena through the hydraulic circuit redesign and change. The optimized hydraulic circuit has been simulated by the AMESim softwareto verify the feasibility of optimization ideas, which provide the reference and theoretical support for the next step hydraulic modification and optimization.
