Clarification about Component Mode Synthesis Methods for Substructures with Physical Flexible Interfaces

Flexible physical interfaces

Flexible Physical Interfaces Nicolas Villar Human-computer interface devices are rigid, and afford little or no opportunity for end-user adaptation. This thesis proposes that valuable new interaction possibilities can be generated through the development of user interface hardware that is increasingly flexible, and allows end-users to physically shape, construct and modify physical interfaces f...

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...

Overlapping Component Mode Synthesis

Synthesis and Control of Flexible Systems with Component-Level Uncertainties

An efficient and computationally robust method for synthesis of component dynamics is developed. The method defines the interface forces/moments as feasible vectors in transformed coordinates to ensure that connectivity requirements of the combined structure are met. The synthesized system is then defined in a transformed set of feasible coordinates. The simplicity of form is exploited to effec...
