摘要

PPROBLEM TO BE SOLVED: To accurately determine a viscoelastic characteristic of a time area in a method for determining the viscoelastic characteristic of the time area represented by the sum of exponential functions of time from frequency distribution of viscoelastic values of a material, and to accurately calculate a physical characteristic depending on a time in a simulation method performed using a simulation model provided with a viscoelastic characteristic in which numerical analysis can be performed. PSOLUTION: As distribution errors of the frequency distribution used when determining the viscoelastic characteristic of the time area from the frequency distribution of the viscoelastic of the obtained material, error of a value of storage/accumulation elasticity, error of a value of loss elasticity, error of a value of loss tangent, error of a value of a slope of the storage/accumulation elasticity relative to frequency, error of a value of a slope of the loss elasticity relative to the frequency, and error of a value of a slope of the loss tangent relative to the frequency are used, the viscoelastic characteristic of the time area is determined such that the distribution error becomes smaller than a predetermined threshold value. Further, the physical characteristic is calculated by the simulation making the viscoelastic characteristic of the time area as an input. PCOPYRIGHT: (C)2008,JPO&INPIT

要解决的问题：在一种确定时间区域的粘弹性特性的方法中，该方法用于根据材料的粘弹性值的频率分布确定时间的指数函数之和来表示该时间区域的粘弹性特性，并且在使用具有可进行数值分析的粘弹性特性的模拟模型的模拟方法中，根据时间精确地计算物理特性。

解决方案：作为从获得的材料的粘弹性的频率分布确定时间区域的粘弹性特性时所使用的频率分布的分布误差，存储/累积弹性值的误差，损失值的误差弹性，损耗正切值的误差，储能/蓄积弹性的斜率的值相对于频率的误差，损耗弹性的斜率的值相对于频率的误差，以及α的值的误差使用损耗正切相对于频率的斜率，确定时间区域的粘弹性特性，使得分布误差变得小于预定阈值。此外，通过将时间区域的粘弹性特性作为输入的模拟来计算物理特性。
