5.采用通用的试验分析方法,对试车台进行了动静态标定和热试车考核试验,试验结果表明,本文试车台能够很好的兼顾稳态和动态测试,具有较高的测试精度和动态性能,综合性能优于已有试车台。
Combining physical demand, this paper designs a test-bench for low thrust liquid rocket engine within 5～100N to remedy the insufficiency of the test bench in existence. It can both comprise steady and dynamic test very well. The results of simulating and firing show that its all-round properties precede the test benches there have been.
Main work and conclusions of this paper are as following:
1. According to the technology index of the test of the low thrust liquid rocket engine within 5～100N,this paper select the measurement scheme. After the technology difficulties of the test having been studied, a general plan is established.
2. This paper designs the details of test bench according to general plan. The test bench adopts big mass design and ceramic thick film sensor technology. And static state standardization can be made automatically. The test bench possesses certain shock insulation and heat shielding ability. Its monolithic structure is compact and application function is perfect.
3. Utilizing finite element method, this paper simulates the test bench and found its fundamental performance parameter. Results show that the test bench possesses favorable steady and dynamic ability, and the structure can satisfy strength requirements at the same time.
4. The paper reads up the relationship between free running frequency of press-leading tube and the substance in it and its structure. The paper also studies the heat conduct character of press-leading tube when the substance in it is water. The fundamentals are derived and will offer gist to the application design of press-leading tube.
5. Using universal orientation analysis method, the paper assesses the test bench through dynamic and steady calibration and hot firing. Results show that this test bench comprises both steady and dynamic test very well. It presents superior measuring accuracy and dynamic properties. Its all-round properties precede the test benches there have been.
