  • CHAPTER 9 – The Stress Analysis Environment
    Up and Running with Autodesk Inventor Simulation 2011, 2010
    Co-Authors: Wasim Younis
    Abstract:

    Publisher Summary The finite element method (FEM) is a mathematical/computer-based numerical technique for calculating the strength and behavior of engineering structures. Autodesk Inventor— and much other Analysis software—is based on the FEM, where, simply, a component is broken down into many small elements. There are three methods within Autodesk Inventor Simulation that can be used to enhance the accuracy of the results: P-refinement, H-refinement, and higher order elements. Autodesk Inventor Simulation is only capable of performing linear Analysis, where components have small deformations, under operational loading conditions. On the other hand, nonlinear Analysis is typically involved when components are experiencing large deformations and thus component material can deform beyond the elastic limit. This chapter describes static Analysis. It is an engineering discipline that determines the Stress in materials and structures subjected to static or dynamic forces or loads. The aim of the Analysis is usually to determine whether the element or collection of elements, usually referred to as a structure or component, can safely withstand the specified forces and loads. This is achieved when the determined Stress from the applied force(s) is less than the yield strength the material is known to be able to withstand.

  • DP8 – Motion Load Transfer Analysis: Structural Validation of Mounting Lugs
    Up and Running with Autodesk Inventor Simulation 2011, 2010
    Co-Authors: Wasim Younis
    Abstract:

    This design problem is follow-on from Design Problem 3 and highlights the effective use of Dynamic Simulation to validate the structural integrity of the mounting lugs. The force is exported from the simulation study and is directly used in the Stress Analysis Environment, removing the need to apply loads and restraint. The main requirements of this design problem are to determine maximum Stress in the mounting lugs when the ramp is fully loaded and factor of safety—for example, the fatigue life could be predicted. The design criteria to be used for this design problem include: The material to be used is mild steel, the factor of safety required is 2, and impact loading is not taken into account.

  • Up and Running with Autodesk Inventor Simulation 2011 - DP9 – Multiple Motion Load Transfer
    Up and Running with Autodesk Inventor Simulation 2011, 2010
    Co-Authors: Wasim Younis
    Abstract:

    This chapter explains the design problem that is follow-on from Design Problem 4 and highlights the effective use of Dynamic Simulation to validate the structural integrity of the connecting rod. The force is exported from the simulation study and directly used in the Stress Analysis Environment, removing the need to apply loads and restraints. The main requirements of this design problem are to determine: maximum Stress in the connecting rod while in operation, maximum deflection in the connecting rod, and factor of safety—for example, the fatigue is predicted. In addition to the requirements, the design criteria to be used for design problem are the following: the material to be used is mild steel, the factor of safety required is 5, and piston (minimum weight is 350 g).

  • Chapter 17 – The Frame Analysis Environment
    Up and Running with Autodesk Inventor Simulation 2011, 2010
    Co-Authors: Wasim Younis
    Abstract:

    Publisher Summary Frame Analysis is associated with analyzing large structures mainly comprising uniform cross-section channels/frames. Some of the examples include bridges structural platforms and towers. Frame Analysis, within Autodesk Inventor Simulation, allows defining criteria for static and modal Analysis, including preStressing. In addition, frame Analysis uses beam elements instead of the 3D tetrahedron elements used within the Stress Analysis Environment. A simple beam element comprises two nodes, one at each end, and has three translational and three rotational degrees of freedom (DOF) six in total. Frame Analysis graphic window displays the model geometry and simulation results. Updates to show the current status of the simulation, including applying boundary conditions and loads with the help of view manipulation tools. The process of creating an Analysis involves four core steps: idealization—creating channels using content center and/or frame generator; boundary conditions idealization—creating channels using content center and/or frame generator apply loads and constraints and apply/modify connections beam release and rigid links; run simulation and analyze–analyze, and interpret results; and optimization—customizing beam properties—change materials.

  • Weight Optimization Of A Lift-Tipping Mechanism For Small Solid Waste Collection Truck
    International Journal of Scientific & Technology Research, 2014
    Co-Authors: Vitus M. Tabie, A. K. Fiagbe
    Abstract:

    This paper deals with Optimization of a lift-tipping mechanism for a small solid waste collection truck. Finite element Analysis was performed on a linkage mechanism that operates the tipping mechanism. The exercise involved validating the design changes made in the Stress Analysis Environment. The work flow was repeated until the weight of the designs was optimized against the design criteria. Siemens Solid Edge ST3 software package, NX Nastran (7) solver was used in the optimization process. The weight of the linkage mechanism has been reduced from 11.6 kg to 7.5 kg which represents 35.4% reduction in weight. Key Terms: Optimization, Finite element modelling, simulation ————————————————————

  • NUMERICAL Analysis OF A CANTILEVER BEAM AND VALIDATION USING THEORETICAL METHODS WITH APPLICATION TO UNIT DELIVERY
    Authorea, 2020
    Co-Authors: Dominic Onimowo, Emmanuel Onimowo
    Abstract:

    This paper investigates the deflection and bending Stress in a cantilever beam of uniform rectangular cross section with a point load using a 3D Finite Element (FE) model. The results are validated using the Bernoulli-Euler’s elastic curve theory equations. The research aims to study and analyse the static Analysis of a rectangular beam considered to be isotropic. During this Analysis, the displacement is assumed to be small, the material exhibits a linear Stress strain relationship i.e.: obeys Hooke’s law, there is no change of magnitude, orientation or distribution of the load applied and the effect of gravity are negligible hence with of the beam is not accounted for in this Analysis. The simulation is carried out in the Autodesk Inventor Stress Analysis Environment and validated using theoretical methods after which the effects of point loads on structural integrity and mechanical properties are studied.
