Characteristic constraint modes for component mode synthesis [PDF]
AIAA Journal, 1999 Abstract In this paper, a technique is presented for improving the efficiency of the Craig-Bampton method of Component Mode Synthesis (CMS). An eigenanalysis is performed on the partitions of the CMS mass and stiffness matrices that correspond to the so-called constraint modes.

Modal energy propagation method in coupled systems of rigid and flexible structure
Nihon Kikai Gakkai ronbunshu, 2022 Since the noise generated by mechanical structures affects the merchantability, it is important to predict it at the design stage. Statistical energy analysis (SEA), which solves the energy equilibrium equation between subsystems, is widely used to ...

Improved Craig–Bampton Method Implemented into Durability Analysis of Flexible Multibody Systems
Actuators, 2023 The Craig–Bampton method is frequently applied in most commercial multibody dynamic software. Nevertheless, the Craig–Bampton modes only represent the free-free modes in flexible multibody systems.

Distributed multilevel optimization for complex structures [PDF]
, 2007 Optimization problems concerning complex structures with many design variables may entail an unacceptable computational cost. This problem can be reduced considerably with a multilevel approach: A structure consisting of several components is optimized ...

Substructuring of a Petrol Engine: Dynamic Characterization and Experimental Validation
Applied Sciences, 2019 In this work, the vibration behavior of a 4-cylinder, 4-stroke, petrol engine was simulated by leveraging on the Finite Element Method (FEM). A reduced modelling strategy based on the component mode synthesis (CMS) was adopted to reduce the size of the ...
