An analysis has been made of the stability of the outer facing-sheet for the composite structure with double cylindrical shells on the basis of a previous article by the same authors. Taking advantage of the fact that the circumferential membrane stress can be decreased, the authors have developed the concept of the equivalent cylindrical shell and from the theory of stability of cylindrical shell, a new formula for the calculation of the stability has been derived.

In this paper the author has discussed two foundamental methods--control of tractive force and control of slippage ratio which in testing the wheel or crawler tractor.In order to meet the testing requirmets in paddy field, the author proposed a new slippage control mechanism added to the tractors which are in mass production, the author also explicated the new method principles and its advantages, and a testing track-laying chassis has been rebuild according to this new method.The test result of the said chassis tried in the paddy field is shown on data sheet, and some tractive characteristic curves of tested track are given.Finally, according to the analysis and test result stated, an appropriate conclusion has been drawnout.

本文叙述了对轮子或履带试验的两种基本方法——控制牵引力法和控制滑转率法。在对已有的滑转率控制机构分析的基础上,为满足水田中试验的需要,提出在成批生产的拖拉机上加装滑转率控制机构的新方案,论述了这种方案的原理,说明了它的优点。介绍了按这种方案改装的试验用履带底盘。示出用该底盘在水田中试验结果的一组数据,画出被试履带行走装置在试验地中的牵引特性曲线。最后根据上述问题的理论分析和试验结果提出相应的结论。

Three ways-machining, embedded sheet and tension process-used usually with the forming of a simulated crack on the photoelastic specimen are given in this paper. The first and the second ways can only give a notch crack on the specimen, but it is the third that can produce a perfect "natural crack" (or its width is approximately zero). The effect in the crack specimen on which the crack is formed in different ways and the photoelastic experiment is made to determine SIF K_I is analyzed. Some distinguishing...

Three ways-machining, embedded sheet and tension process-used usually with the forming of a simulated crack on the photoelastic specimen are given in this paper. The first and the second ways can only give a notch crack on the specimen, but it is the third that can produce a perfect "natural crack" (or its width is approximately zero). The effect in the crack specimen on which the crack is formed in different ways and the photoelastic experiment is made to determine SIF K_I is analyzed. Some distinguishing features for determining SIF K_I in "natural crack specimen" are presented. The experiment shows that the measurment in "natural crack specimen" possesses several advantages such as wider range of data collection, stabler values and clearer distribution regularity of the test points on T-N curve, therefore higher accuracy of results measured can be obtained. So "natural crack" specimen is a perfect test specimen. In addition, three criterions for assessment of quality of the crack specimen are herein provided.

本文总结了目前光弹性法研究断裂力学中于模型试样上制作模拟裂纹所用的三种方法——机械加工,夹片和张拉法。前两种方法只能在试件上形成切口状裂缝,而第三种方法可以形成品质优良的“理想尖裂纹”(即裂缝宽度为零的尖裂纹)。本文分析了在用不同方法所形成的裂纹试件,对光弹性法实验确定K_1的影响。给出“理想尖裂纹”试件作K_1测定中所呈献的特点.实践表明,在“理想尖裂纹”试样上进行测定时,由于数据采集范围大,数值稳定性好,T—N曲线上试验点分布规律性明显,能带来高精度的测定结果。此外,文中还提出评定裂纹试样的三条质量标准。
