自行火炮动力舱整体吊装支架静动态有限元分析

自行火炮动力舱整体吊装支架可大大提高自行火炮的可维修性，提高其战斗力和生存力，是自行火炮动力舱的发展方向．本文设计了我国第一个自行火炮动力舱整体吊装支架，并对该支架进行了静态和动态分析．有限元分析结果表明，该支架刚强度能够满足设计要求，在发动机和路面激振的作用下，支架不会产生共振．

Static And Dynamic FEM Analysis Of The Integral Hoisting Stand For A Tracked Vehicle Powertrain Cabin

The integral hoisting stand for a tracked vehicle powertrain cabin can effectively increases the maintainance ability,the militancy and the vitality of the tracked vehicle.It is the trendency in the design of the powertrain cabin of the tracked vehicle in the world.In this paper,the first integral hoisting stand for a powertrain cabin in china is designed and the FEM analysis for the stiffness an strength of it is given.The results of the FEM analysis show that the structure of the integral hoisting stand for the powertrain cabin is reasonable and its stiffness and strength can meet the design requirements.The results also show that there is no resonance in the integral hoisting stand under the stimulation of the engine and road.
