Type yg008 multi - filament yarn tensile strength tester is to determine the tensile strength and percentage elngation of raw silk and other linear materials ; print , output various data
产品说明：本仪器用于测定生丝和其他线形材料的断裂强度和伸长率，并打印输出各项数据。
Second , through employing the 3 - d finite element model and the dual objective function inversion method developed in this paper , and taking the measured fundamental frequency of system and the structure response to a harmonic excitation at the top of structure in field as the reversion objectives , the linear material parameter inversion is performed in ansys by using ansys parameter design language ( apdl )
第二,采用三维实体有限元模型和本文提出的双目标函数反演方法,把现场测试得到的系统基频和顶部激振下实测的结构动力响应作为反演目标,利用ansys参数设计语言( apdl ) ,在ansys软件中实现了系统材料线性参数的反演。
