  1. 41. Finite Element Modeling of Rubber Bushing for Crash Simulation - Experimental Tests and Validation

    University essay from Lunds universitet/Byggnadsmekanik

    Author : Oscar Jesus Centeno Gil; [2009]
    Keywords : Technology and Engineering;

    Abstract : Until recently, the general level of detail in full car crash models has not allowed a physical modeling of rubber bushings with solid elements. This is partly because of the difficulty in modeling the complex characteristic of rubber, but also due to limited understanding of the mechanical properties of rubber materials. READ MORE

  3. 42. Modeling of mechanical motions in a sewing machine

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Johan Tegsten; [2008]
    Keywords : ;

    Abstract : To avoid high costs and delays, it is important to correct mistakes and to solve problems as early as possible in the development process. The aim for this master thesis is to develop dynamic models to describe the mechanical motions in an advanced sewing machine. READ MORE

  4. 43. Modeling and Balancing of Spherical Pendulum using a Parallel Kinematic Manipulator

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : David Barrio Vicente; [2007]
    Keywords : Technology and Engineering;

    Abstract : The balancing act of an inverted pendulum with a robotic manipulator is a classical benchmark for testing modern control strategies in conjunction with fast sensor-guided movements. From the control design perspective, it presents a challenging and difficult problem as the system is open-loop unstable and includes nonlinear effects in the actuators, such as friction, backlash, and elasticity.

  5. 44. Introduction of vegetation in large scale hydrodynamic models

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Goncalo Ferreira Cardoso; [2005]
    Keywords : Environmental technology; Väg- och vattenbyggnadsteknik; soil mechanics; vegetation modelling; vegetation modeling; lake hydrodynamics; shallow lakes; hydrodynamic models; hydraulics; Technological sciences; Teknik; Civil engineering; offshore technology; hydraulic engineering; pollution control; Miljöteknik; kontroll av utsläpp; Technology and Engineering; Earth and Environmental Sciences;

    Abstract : Vegetation is known to have different effects in shallow water environments, including changes in hydrodynamics. This often creates the need to include vegetation in large scale hydrodynamic models, which nowadays can already be achieved using some software packages available in the market. READ MORE

  6. 45. Analysis and Measurements of Vehicle Door Structural Dynamic Response

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Maskinteknik (CI)

    Author : Mats Hörnlund; Alexander Papazoglu; [2005]
    Keywords : Technology and Engineering;

    Abstract : In order to reduce lead time and cost in the product development of vehicles more development will be made virtually. However, the predictability capability of simulation models is questioned and the simulation models need to be correlated versus hardware measurements and modeling techniques improved. READ MORE
