设计简介
摘要：导弹等飞行器特别是对对空发射等高质量、高精度的武器，它们有很高的要求，要有很好的机动性能，导弹的机动性能越好，要求它的整体结构强度就越高，承受机动过载的能力越强，发动机的结构性能就要求越高，所以我们在生产使用前必须对一些参数进行实验性测试，这样才能保证它在高空过载情况下正常放心使用，并且保证其误差在允许范围内，因此，我们必须设计出相关仪器来测试出其参数, 因此，所以发动机过载模拟实验台产生了。
发动机过载模拟实验台是通过传动系统使固定在旋转架上的发动机转动而产生离心力，在过载情况下测试其某些性能参数的变化情况。通过离心机可以实现发动机内的弹道参数、离轴加速度、壳体应变以及温度等的测量.现主要工作就是系统的传动设计和测试件的夹紧。研究内容：了解该课题的特点以及发展状况.传动系统方案的设计、比较与确定.零件设计、选择、计算以及图纸的初步绘制,工件的夹紧方案的设计、比较与确定,生产部门讨论加工问题.
此次设计的实验台在不作点火的情况下，对可两个发动机进行测试，也可作单件测试。测试件一般在2m以内，重量不超过100㎏，具有结构简单、紧凑，工作可靠、维护方便等特点。实验台的设计目标是要满足地面普通热试车试验，在法向加速度作用下对飞行器进行性能检测，不至于导弹在机动飞行中失效。

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
