Compliant mechanisms have the advantages of simplification in manufacturing and assembly, reducing cost, weight, wear, backlash and noise owing to their intrinsic structures. The aim of this study is to develop optimization methods to design reliable, high performance and easily manufacturable compliant equivalents of rigid body mechanisms used in industrial applications by utilizing the advantages of compliant mechanisms over rigid body mechanisms. Two particular mechanisms from the industry, namely a bistable field of view switch mechanism of optical systems and an adaptive finger mechanism for robot grippers are discussed in this thesis. The pseudo-rigid-body model is used for the design of bistable field of switch mechanism that is partially compliant while an analytical large deflection beam model is utilized to design the adaptive finger mechanism that is fully compliant. The optimized solutions satisfying the required motion conditions and desired force characteristics are also investigated through finite element analysis. The results are compared and the proposed designs are validated through physical prototypes.

on the analysis and design of a new type of partially compliant mechanism
Tanık, Engin; Söylemez, Eres; Department of Mechanical Engineering (2007)
In this study analysis and design procedures of partially compliant mechanisms using two degree of freedom mechanism model are developed. The flexible segments are modeled as revolute joints with torsional springs. While one freedom is controlled by the input to the mechanism, the motion of the parts are governed both by the kinematics and the force balance. The procedure developed for the analysis of such mechanisms is shown on two different mechanisms: a five link mechanism with crank input and slider out...
Simulator of an additive and subtractive type of hybrid manufacturing system
Dilberoğlu, Mecid Uğur; Yaman, Ulaş; Dölen, Melik (2019-06-24)
Additive Manufacturing (AM) facilitates the production of intricate objects despite its weakness in attainable part quality and fabrication speed compared to the conventional manufacturing methods. To alleviate the problems arising as a natural outcome of AM methods, hybrid technologies become viable options by employing concurrent manufacturing procedures, e.g. synergetic additive and subtractive manufacturing (SM) actions. Hybrid workstations have recently opened up new dimensions to 3D-printing industry,...
Engineered Deregulation of Expression in Yeast with Designed Hybrid-Promoter Architectures in Coordination with Discovered Master Regulator Transcription Factor
Ergun, Burcu Gunduz; Demir, Irem; Ozdamar, Tuncer H.; Gasser, Brigitte; Mattanovich, Diethard; Çalık, Pınar (2020-04-01)
Engineered promoters are key components in the cell-factory design, allowing precise and enhanced expression of genes. Promoters having exceptional strength are attractive candidates for designing metabolic engineering strategies for tailoring de novo production strategies that require directed evolution methods by engineering with de novo synthetic biology tools. Here, the custom-designed AOX1 hybrid-promoter architectures in coordination with targeted transcription factors are shown, transcriptionally rew...
Investigation of decoupling techniques for linear and nonlinear systems
Kalaycıoğlu, Taner; Özgüven, Hasan Nevzat; Department of Mechanical Engineering (2018)
Structural coupling methods are widely used in predicting dynamics of coupled systems. In this study, the reverse problem, i.e. predicting the dynamic behavior of a particular subsystem from the knowledge of the dynamics of the overall system and of all the other subsystems, is studied. This problem arises when a substructure cannot be measured separately, but only when coupled to neighboring substructures. The dynamic decoupling problem of coupled linear structures is well investigated in literature. Howev...
Hybrid-architectured promoter design to engineer expression in yeast
Gündüz Ergün, Burcu; Çalık, Pınar (Academic Press Inc., 2021-01-01)
Engineered promoters are key components that allow engineered expression of genes in the cell-factory design. Promoters having exceptional strength are attractive candidates for designing metabolic engineering strategies for tailoring de novo production strategies that require directed evolution methods by engineering with de novo synthetic biology tools. Engineered promoter variants (EPVs) of naturally occurring promoters (NOPs) can be designed using metabolic engineering strategies and synthetic biology t...
