تحلیل مودال با استفاده از روش component mode synthesis (cms) همراه با صحه گذاری تجربی

در این پروژه روش های تحلیل مودال سازه هایی که از چند زیرسازه تشکیل شده اند بررسی شده است. از جمله این روش ها روش سنتز مودها است که ابتدا بطور مختصر تاریخچه فعالیت هایی که در این زمینه تا کنون انجام شده است بررسی شده و سپس الگوریتم های مختلف این روش مورد مطالعه قرار گرفته است. از جمله این الگوریتم ها روش سطوح مشترک ثابت و روش سطوح مشترک آزاد است طوریکه روش اول با دقت بیشتر و تنها برای داده های ت...

Component Mode Synthesis in ANSYS Workbench Simulation

At ANSYS Workbench 11.0, the ANSYS Rigid Dynamics add-on module enables users to define joint connections in complex kinematic assemblies. This ability to model rigid and flexible parts in ANSYS Workbench Simulation via joints is beneficial since the rigid parts are modeled with mass and rigid links (that is, rigid contact elements), thus providing load transfer capabilities and allowing users ...

Deviatoric component modes in an interval component mode synthesis procedure

This paper focuses on the integration of interval uncertainties in the procedure of the Component Mode Synthesis (CMS) method used for the dynamic analysis of large finite element (FE) models in mechanical engineering. Two methods are combined in this work: the Interval Finite Element Method for the nondeterministic eigenvalue and frequency response function analysis of FE models with uncertain...
