The paper presents the modeling and simulation of a new parallel robot concept with 6 Degrees of Freedom (DOF), called PARA-SILSROB used for the single incision laparoscopic surgery. The paper focuses on the inverse kinematics, the preliminary design, and the robot...

... of systems and help describe their complex behavior. But the challenge in Digital twin model building is still exist, it cannot accurately reproduce the physical resources, and the introduction of error will lead to the differential extension of virtual system from physical space. The challenge is how...

... Abstract In industry and academia, designers and engineers use prototyping at various stages in the design process to evaluate progress, archive process, assess viability, and communicate mental models to a team. Cognitive processes not only play a huge role during the design process, but also...

... Systems Modeling is a mandatory course in this major. This course uses a technique of power flow called bond graphs to model mechatronic systems. This technique is not discipline specific and students with different disciplinary background can easily understand and master it. Recently, the use of Simscape...

... Abstract Modeling of multiple objectives in a decision and multilevel decisions are important in decision-based concurrent design. In this paper we address these twin issues in the context of a rotating disk. The initial mathematical description, referred to as the baseline model...

... Abstract In this paper we investigate the vibration characteristics of a rotor system with flexible disks. The coupled vibration mode between rotating shaft and the flexible disk are analyzed for lateral and axial vibrations respectively. Gyro and sheer effects are considered for the modeling...

... Abstract There is an increasing demand in the conceptual design for more intuitive methods for creating and modifying free-form curves and surfaces in CAD modeling systems. The methods should be based not only on the change of the mathematical parameters but also on the user’s specified...

... in developing such a framework is how can we define and assess the role of knowledge and how different ways of organizing knowledge may impact on the overall performance of a collaborative engineering team ? In this paper, we introduce the notion of knowledge structure , and present our initial model...

... is important can be simplified if the structures of mathematical models, computational problems and algorithms are represented by means of dichromatic graphs. Playing the role of unusual route maps, these graphs allow the student to understand at a glance what a computational problem is, and the flow...

... Abstract This paper proposes a modeling technique for motion and vibration in flexible structures. We call this technique ‘extended reduced order physical model’. Because vibration is generally influenced by motion, it is necessary to analyze vibration together with motion. New modeling...

.... This paper presents a method that models known design concepts and manages their functional couplings for designers to achieve these difficult balances systematically during concept improvement. The modeling involves three steps. The first is to represent the known design concept as a dual-hierarchy...

... Abstract Parallel kinematics manupulators (PKM) are established robotic systems. Yet there is no established modeling approach that takes into account the special kinematics of the (usually structurally identical) limbs. In this paper a modeling approach is proposed that accounts...
