Traditional fixing method of the spring causes measuring error and it's unallowable for this miniature spring. So the whole measuring instrument is designed systematically and the development of new fixing and positioning devices are focused on. The new fixture method is analyzed by FEA and results are good.

随后各章论述了新型刚度测试仪器的研制过程，对于传统弹簧的安装夹紧方式在刚度测试中引起的测量误差进行了分析，对于微小型扭转弹簧的刚度测试而言，这是不能允许的超大误差，为此，在系统地设计完成了整体测试装置的基础上，重点研制了新颖的弹簧的定位夹紧结构，对于该定位夹紧结构方案也利用有限元分析软件进行了仿真分析，结果表明比较理想。

In ground testing research of some large airplane and aerocraft, suspend structure of sky need to be simulated. As a lower natural frequency and a good underprop, air spring can satisfy the need of the testing research. In this paper, a calculating model of air spring was built by ABAQUS.

一些大型的飞机，航天器等在做地面试验的时候，需要模拟空中的悬浮结构，由于自身的固有频率比较低，所以需要更低固有频率的支撑物，而空气弹簧正好可以满足试验的需要。

For eliminate redundant stress in spring unit brought by continuously variation of strain,in wind spring device,the adopt spiral output wheel with continuously variant radii was used and the variation of moment can be canceled out by variation of radii,the approximate constant output force can be obtained.

为消除弹簧装置中应力随应变不断变化而产生的多余应力，在卷簧结构中，采用螺旋变径输出轮，用半径的变化抵消力矩的变化，获得近似恒定的输出力。在精度要求不高的场合，采用此方式可形成简便可靠的近似恒力的弹簧装置

To prove the validity of the universal method, spring force characteristic of a certain electromagnetic relay was calculated by the method, and the real spring force characteristic was tested with a testing equipment.

采用该方法对某型号电磁继电器的反力特性进行了计算，并以反力特性测试装置对该继电器反力特性进行了测试。

If all comes down to the Spring Wheat plantings on Tuesday's 3:00p report. If North Dakota and Minnesota finally got to planting Spring Wheat, the threat of several million acres going unplanted will fade but with a week of dry weather shows no intent we will take out 6.00 and push to 6.22. A break early next week sets up 5.64 as support. To achieve that we need a dry six to ten day forecast and a Tuesday Planting Report over 70% seeded in those two states.
