Rack centrifugal acceleration to overload simulation design
Abstract: The aircraft such as missile is the high quality and precision weapon lauched by air to air .They have high requirement and have excellent maneuverability. The better maneuverability the missile have, the higher the intensity of holistic structure requires .The better it bear the mobile over loading,the higher the structure capability of engine requires.To ensure that the missile can run normally in the case of high-position and overloaded, and also make sure that error is under control. We must hold a experimental test to some parameter before it is made and used.Therefore, we must design relative apparatus to test parameter and the overload simulation laboratory bench of the engine has been designed..
The overload simulation laboratory bench of the engine is through the transmission system make the engine which install at the rotators shelf to rotate, that make the engine has the centrifugal force, tests its certain performance parameter change in the overload situation.pass left scheming can realize launch machine and leave the stalk acceleration, hull adapts to changes and the diagraph that temperature wait. Presently the main work is the system transmission design and measures the test sample clamping. The main study content include:learn the character of the task and the development trend,the design ,compare and confirmation of transmission system project, the design ,choice and calculate of part and the principium protract of blueprint. the design ,choice and calculate of the the project of clamp,the discussion of the problem of manufacture between production department.
This experiment pedestal of design under the condition of not make some fire, to can two launch the machine to carry on the test, also can make a test.Test the piece generally at 2 m in, weight not over 100 Kg, have the structure simple, tightly packed, work dependable, support the convenience etc. characteristics. The aim of the design of this laboratory bench is to satisfy the common hot test-drive on the ground and to test the capability of the aircraft with the function of the vertical acceleration. The missile will not invalidation under this condition
Keywords:Leave the scheming revolve the set deliver the motive over loading invalidation
