【摘要】 设计了基于Matlab/Simulink的高分子粘弹性计算机辅助教学(CAI)软件。计算机程序由各种功能模块根据聚合物的粘弹性原理连接组合而成,通过点击模块可以输入和修改实验数据和模拟参数,运行后可以从虚拟的“示波器”、“数字显示屏”和“XY记录仪”上显示模拟结果。该软件可演示和模拟高分子材料的静态和动态粘弹性行为,如形变的滞后效应、动态力学损耗、Boltzmann叠加和自由振动衰减曲线等。该软件不仅可用于高分子物理课程的教学演示,也能够应用于高分子材料的设计和研究。更多还原

【Abstract】 CAI(computer assistant instruction) software of polymer viscoelasticity was designed based on Matlab/Simulink.The computer programs consisted of various functional modules according to the viscoelasticity priciple of polymer.Experimental data and simulation parameters may be input and modified by clicking the corresponding modules.The direct-viewing simulation results will be obtained from the output modules such as oscilloscope,digital display and XY recorder. This software can demonstrate and simulate the viscoelasticity behavior of polymer both in static and dynamic state,such as hysteresis effect,dynamic mechanical loss,Boltzmann superimposition of strain and free vibration decay curve.The software can be used not only for instruction demonstration in polymer physics course,but also for design and study of polymer materials.更多还原
