pressure strength inner body radome



由硬脆材料制成的各类罩体在成型过程中有时会出现内部缺陷,性能参数需要测量,本文介绍了一种检测试验件的静强度与破坏强度的方法,由计算机控制完成整个试验过程,对试验件采用机械定位,在罩体大端内外两侧布置橡胶胎,同时向橡胶胎内充入高压油,利用液压动力夹持天线罩,向罩体内腔充入高压气体,通过观察罩体是否破损来检验其静强度与破坏强度。


 












外文摘要





 



A method of filling inner cavity of radome body with high-pressure gas is provided in this paper, which is used to examine the static strength and destroy strength of test piece. The testing process is accomplished due to the control of computer. The test piece is mechanically positioned. Two rubber tyres are respectively arranged on inner and outer side of a larger end of the radome body, while high-pressure oil is filled into the rubber tyres. The radome body is clamped and supported by hydraulic power. Then fill the inner cavity of radome body with high-pressure gas. By observing if the body is to be broken, the static strength and destroy strength thereof is examined.
