Component Mode Synthesis of Structures with Geometric Stiffening in Msc/nastran
Implementation of modal synthesis in MSC/NASTRAN is usually done using structural solution sequence based Direct Matrix Abstraction Programs, DMAPs. However, modal synthesis in MSC/NASTRAN without using structural solution based DMAPs is possible. But either method is tailored towards supporting components that have no non-linearity. Certain components, such as the solar arrays of the space sta...
متن کاملMSC/NASTRAN Based Component Mode Synthesis Analysis Without The Use of DMAPs
Component mode synthesis method of analyzing large structures is a very powerful and efficient tool available in MSC/NASTRAN. For many years the method based on MSC/NASTRAN has been widely used in the aerospace and automotive industries where different physical components are often designed and modelled by different organizations, departments or groups. For forward and backward flow of data it ...
متن کاملGpu Computing with Msc Nastran 2013
Current trends in HPC (High Performance Computing) are moving towards the use of many core processor architectures in order to achieve speed-up through the extraction of a high degree of fine-grained parallelism from the applications. This hybrid computing trend is led by GPUs (Graphics Processing Units), which have been developed exclusively for computational tasks as massively-parallel co-pro...
متن کاملEfficient Component Mode Synthesis with a New Interface Reduction Method
When the finite element model of a complex structure is partitioned into substructures in order to enable component mode synthesis (CMS), there may be a large number of degrees of freedom (DOF) on the interface between components. In such a case, the constraint-mode-related coordinate transformation at the substructure analysis stage becomes computationally expensive, and the CMS model may be c...
متن کاملتحلیل 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...
