摘要

提出一种基于ANSYS二次开发功能的数值模拟技术,用来模拟用户自定义的非线性应力应变关系,给出基于ANSYS的用户自定义滞回模型开发方法的操作流程。同时,利用这项技术实现EDR阻尼器和拟线性变摩擦滞回阻尼器的滞回特性,在AN-SYS中实现阻尼器单元的负刚度特性,数值分析验证了这项技术的正确性,具有极高的实用性。
A numerical simulation technology based on secondary-development function of ANSYS is presented herein.It can be used to simulate user-defined nonlinear stress-strain relationship.The operating procedure of development approach for user-defined hysteretic model based on ANSYS is given.The hysteretic characteristics of EDR damper and pseudo-linear hysteretic curve damper with friction-variable characteristics are realized using this kind of technology.The negative-stiffness characteristics of damper elements are also realised based on secondary-development function of ANSYS.The validity of this kind of technology is verified in numerical analysis.The very well practicability would be expected.
