Abstract

The invention belongs to the technical field of testing and relates to a preparing punch for a platy concentric circular ring sample. The concentric circle combination body is used for guaranteeing that the inner circle and the outer circle are concentric, an elastic rubber gasket is arranged between two punch bodies, and therefore damage to the sample by sample preparing is reduced. The preparing punch for the platy concentric circular ring sample is composed of the pair of concentric circle punch bodies and is characterized in that the inner circle punch body (1) and the outer circle punch body (2) respectively comprises a punch body and a matching section matched with the corresponding punch body. A flexible backing ring (3) is arranged between the punch bodies. The height of bottoms surface of the backing ring (3) is larger than or equal to the height of the plane of the blade parts of the punch bodies. The preparing punch for the sample is high in concentricity and simple in structure, because the sample is extruded and buffered through the rubber gasket in the preparing process of the sample, the protrusion or edge breakage of the circular ring sample can be greatly buffered, and the flat and regular sample is easy to obtain. In the preparing process of the sample, for a soft or fragile sample, deformation or edge breakage can be buffered, so that the appearance of the prepared sample is regular and complete. The preparing punch is suitable for occasions where the ring sample is manufactured and particularly suitable for occasions, wherein the sample of which electromagnetic parameters are tested through a concentric method is manufactured on the occasions.

Description

—种片状同心圆环试样制样冲子 - to prepare a sample flaky concentric annular ring-like punch

技术领域 FIELD

[0001] 本发明属于测试技术领域,涉及测试样品制备技术,特别涉及微波电磁参数测试技术领域。 [0001] The present invention belongs to the technical field testing, to test sample preparation technique, particularly to a technical field of microwave electromagnetic parameters tested.

背景技术 Background technique

[0002] 电磁参数一般指复介电常数和复磁导率,它们是描述材料与电磁场相互作用的两个基本特征参数,其中复介电常数反映了材料对于电场能量的存储与损耗,复磁导率反映了材料磁场能量的存储与损耗,实部与虚部的量值则分别反映储能与损耗的大小。 [0002] parameter generally refers to electromagnetic complex permittivity and permeability, which are two fundamental characteristics that describe electromagnetic field interacts with material, wherein the material complex dielectric constant reflects the loss for storing electric energy, complex magnetic conductivity of the lossy material reflects storing magnetic energy, the magnitude of the real and imaginary portions respectively reflect the size of the storage and loss. 电磁波在材料中的的传播完全由材料的电磁参数所决定,因此它是隐身材料设计中的关键参数,必须对其进行准确测试。 Propagation of electromagnetic waves in the material is completely determined by the parameters of magnetic material, so it is a critical parameter in the design of the camouflage material, it must be measured accurately.

[0003] 测量材料电磁参数的方法主要分为传输反射法和谐振腔法。 [0003] A method for measuring the electromagnetic parameters of the material is divided into transmission and reflection and resonant cavity. 其中传输反射法是利用所测出的样品的反射和传射系数得到复介电常数或复磁导率,根据所用夹具的不同,又分为同轴法、波导法、自由空间法和开口同轴探头法等,其中同轴法最为常用,同轴法一般用来测量片状固体或者粉末状固体,被测物质为损耗至低损,这种方法对被测件的机械加工精度要求比较高,被测物质的截面必须和空气线或波导的轴线垂直,而且被测物质与传输线或波导之间完全接触,否则会产生一定的测量误差。 Wherein the transmission and reflection is the use of the measured sample reflection and transmission coefficients are complex permittivity exit or complex permeability, depending on the jig, the method is divided into coaxial waveguide method, and an opening with a free space method axis probe method or the like, wherein the method most commonly used coaxial, generally coaxially method for measuring solid flake or powder solid, the test substance to the loss of low-loss, the method is relatively high precision machining of the DUT , and the cross section of the test substance must be an air line or a vertical axis of the waveguide transmission line and the test substance or with full contact between the waveguide, otherwise it will produce a certain measurement error. 同轴法是测试材料电磁参数的常用方法,属于网络参数法,它具有测试频带宽、需要样品量少的特点。 Is a commonly used method of coaxial electromagnetic parameters of the test materials belong to the network parameter method, having a test frequency band, it requires less sample characteristics. 目前应用较广的测试装置是7mm同轴空气线,测试前需要制备形态为内径3.04mm、外径7mm的圆筒或圆环形样品O Currently the widely used testing device is 7mm coaxial air line, requires the preparation of an inner diameter of 3.04mm to form before the test, the outer diameter of 7mm cylindrical or annular Sample O

[0004] 对于片状低反射功能材料电磁参数的测试,一般用冲子来制样,使用口径分别为Φ3.04mm和Φ7ιήπι的冲子冲出圆环状样品。 [0004] For the sheet-shaped low-reflection electromagnetic parameters functional test material, generally used to punch the sample preparation, the use of an annular aperture are punched Φ3.04mm and punch samples of Φ7ιήπι. 在实际操作中,要制得同心度较好的圆环并不容易,由于估计不准确或定位偏差,制得的圆环通常有些偏心。 In practice, to obtain good concentricity ring is not easy, since the estimated positioning error or inaccuracy, the resulting ring is typically somewhat eccentric. 另外,这种方法对于硬度与韧性适中的材料比较合适,对于较软或较脆的材料,边缘容易鼓起或崩落。 Further, this method is suitable for a material of moderate hardness and toughness, to the softer or more brittle material, the edges readily bulge or caving.
