NUMERICAL SIMULATIONS OF SHEAR ... - ltu.diva-portal.o

FINITE ELEMENT MODEL A simplified finite element model is created based on the experiment description given by Fransson and Sandkvist, 1985. The ice rubble is modelled by solid element having shape of 500 mm cube (shown in green colour). One fixed part and one moving part (bracket) modelled with solid element.

Study of an axial loaded sandwich panel - ltu.diva-portal.o

behaviour will be done. This investigation will be carried out through experimentation, finite element modelling and calculations to find resistance values. Ultimately, these results will be analysed and examined and prove if the sandwich panel with 1mm steel plate is able to withstand a 3-storey modular house.

Study of pitch bearings in wind ... - kth.diva-portal.o

bearing load is calculated by assuming a quasi-static loading as the blade completes one revolution. A simplified finite element model is then built where the stiffness of the rollers is modeled onto special connector elements, which consumes less computational resource and still delivers an accurate result.

Simplified finite element bearing modeling - DiVA port

Simplified finite element bearing modeling - with NX Nastran Erik Adolfsson This report was produced at the request of ABB Robotics and the work was conducted at their facilities in Västerås, Sweden. In the development of industrial robots the structures are slimmed to increase the accuracy and speed.

Modeling and Simulation of Brake ... - kau.diva-portal.o

using simulation in finite element (FE) method it should be possible to predict at what frequencies the brakes tend to emit sound. The method chosen for the analysis was the complex eigenvalues analysis (CEA) method, since it is a well-known tool to predict unstable modes in FE analysis. The results from the

Finite Element Modeling of Contact ... - liu.diva-portal.o

Finite Element Modeling of Contact Problems Asim Rashid ... contact interactions are investigated using nite element modeling. In the rst part, a new augmented Lagrangian multiplier method is implemented ... piston rings, bearings and clutches. In many applications, tri-bological interactions of contacting bodies alter the topography of mating ...

Finite Element Modeling of Contact ... - liu.diva-portal.o

Many engineering design optimization problems involve multiple conflicting objectives, which today often are obtained by computational expensive finite element simulations. Evolutionary multi-objective optimization (EMO) methods based on surrogate modeling is one approach of solving this class of problems.

LINEAR AND NONLINEAR FINITE ELEMENT MODELLING AND STRESS .

Figure 1. Isoparametric view of the model. To model the portal crane box girder with four-node tetrahedral element, Msc.Patran/Nastran software was used to finite element analysis using the girder solid model generated by means of Msc.Patran/Nastran. Young’s Modulus (E) is 2.1x105 N/mm2 and Poisson Ratio (ν St) is 0.3 for finite element ...

Modeling of end-plate bolted composite connection in fire .

Simplified model to obtain characteristics of composite joints in fire was proposed. The resulting axial force due to the expansion of the beam in fire was considered. The proposed simplified model was validated by a verified 3-D finite element model. Equations to predict the M–θ relationship considering axial force effect were proposed.

DiVA - Search result - DiVA port

Then the development of the methods were done by generating ideas for bearing models and testing them on simple structures. Nine methods was produced and a tenth, the method used to model bearings today, was used as a reference. The methods was used to build bearing models in a finite element model of a six axis robot wrist.

Stochastic Finite Element Simulations of ... - DiVA port

simplified, parameterized, stochastic vehicle simulation model for the evaluation of passive restraint systems in real-life frontal crashes with regard to rib fracture injuries. Methods. The work was divided into five phases. In phase one, the geometry and properties of a finite element (FE) generic vehicle buck model

DiVA - Sökresultat - du.diva-portal.o

A three-dimensional finite element model of cold pilgering of stainless steel tubes is developed in this paper. The objective is to use the model to increase the understanding of forces and deformations in the process. The focus is on the influence of vertical displacements of the roll stand and axial displacements of the mandrel and tube.

DiVA - Sökresultat - beta.diva-portal.o

The model has less material constants than previous models, and the material constants can more easily be determined from uniaxial experiments. The model was tested by performing simulations of creasing of paperboard with a two dimensional finite element model, that mimiced a laboratory creasing device.

Dynamic behaviour of pot bearings - KTH Diva - mafiadoc.c

The finite element modelling approach used is described in section 5.1 and the case studies are described in section 5.1. The main purpose of these modelling efforts was to indirectly validate the bearing model by using it in simplified models of real bridges, aiming at a reasonably accurate idealization of the fundamental mode of vibration.
