三圆弧波纹膜片(见图1)是一种常用的膜片。膜片的外边缘波可以有不同的大小,虽然都是圆弧波纹,但随边缘波的大小不同,膜片特性,应力值,有效面积也不同。作者利用环壳理论和初参数法,对不同边缘波的三圆弧波纹膜片进行了大量计算,并与实验做了比较,拟合出不同边缘波的三圆弧波纹膜片的工程简便公式,为工程设计提供了实用而可靠的设计公式和方法。
Three circular corrugated diaphragm (see Figure 1) is a commonly used diaphragm. Diaphragm outer edge of the wave can have different sizes, although all arc ripples, but with the size of the edge of the wave, the diaphragm characteristics, stress values, the effective area is also different. By using the theory of ring shell and the initial parameter method, the authors calculated a large number of three circular corrugated diaphragms with different edge waves and compared them with the experimental ones to fit the simple formula of three circular corrugated diaphragms with different edge waves , Provides a practical and reliable design formula and method for engineering design.
