Optimizing the Design of a Coil Spring
http://www.maplesoft.com/applications/view.aspx?SID=153608&ref=Feed
<p>The design optimization of helical springs is of considerable engineering interest, and demands strong solvers. While the number of constraints is small, the coil and wire diameters are raised to higher powers; this makes the optimization difficult for gradientbased solvers working in standard floatingpoint precision; a larger number of working digits is needed.</p>
<p>Maple lets you increase the number of digits used in calculations; hence numerically difficult problems, like this, can be solved.</p>
<p>This application minimizes the mass of a helical spring. The constraints include the minimum deflection, the minimum surge wave frequency and the maximum stress, and a loading condition.</p>
<ul>
<li>the minimum deflection, </li>
<li>the minimum surge wave frequency, </li>
<li>the maximum stress, </li>
<li>and a loading condition.</li>
</ul>
<p>The design variables are the</p>
<ul>
<li>diameter of the wire, </li>
<li>the outside diameter of the spring,</li>
<li>and the number of coils</li>
</ul>

http://www.maplesoft.com/applications/view.aspx?SID=153573&ref=Feed
<p>A manufacturer has designed a fuel pod in NX. The fuel pod has a hemispherical and conical end, and a cylindrical midsection. To minimize material costs, the manufacturer wants to minimize the surface area of the fuel pod while maintaining the existing volume.</p>
<p>This application:</p>
<ul>
<li>pulls the current dimensions of the fuel pod (radius of the hemispherical end, length of the cylindrical midsection, and height of the conical end) from the NX CAD model, </li>
<li>calculates the current volume of the fuel pod,</li>
<li>optimizes the dimensions to minimize the surface area while maintaining the existing volume,</li>
<li>and pushes the optimized dimensions back into the NX CAD model.</li>
</ul>
<p>NOTE: To use this application, you must</p>
<ul>
<li>have a supported version of NX installed, </li>
<li>load canisterOptimization.prt in NX (this is the CAD model of the fuel pod),</li>
<li>ensure the NXMaple link works correctly.</li>
</ul>

TensionControlling RolltoRoll Model
http://www.maplesoft.com/applications/view.aspx?SID=34922&ref=Feed
<p>In this model, the Feed Spool on the left feeds material to the Winder Spool on the right. Two DC motors control this process. The Feeder Controller sets the desired RPM of the Feeder Spool, which determines the material feed rate. The Winder Controller sets the desired tension. In the example, a 40cm wide, 1mm thick spool of polypropylene is fed a length of 1m between the rollers. First, at 1 second, the Winder Spool applies tension to the material at 10% of its yield strength. Next, at 3 seconds, the Feeder Spool is spun up to the desired RPM. The roller properties are set to 1cm thick stainless steel.</p>

Monotonic Plastic Zone Size for Plane Stress and Plane Strain
http://www.maplesoft.com/applications/view.aspx?SID=4249&ref=Feed
This worksheet demonstrates the use of Maple for calculate plastic zone shapes and sizes for plane stress and plane strain for cracks under static loading. The sizes of plastic zones were obtained by equaling VonMises criteria (using Irwin's elastic solutions), to monotonic yield strength of material (Sy). For this reason, the shape and size of plastic zones showed here do not take into account the strain hardening of material within plastic zone. Sizes in polar coordinates r and theta are functions of quadratic relation between elastic stress intensity factor K and Sy (K/Sy)^2. For a established angle theta, the graphic shows the estimated sizes of plastic zones (coordinate r, in meters) for different relations of (K/Sy)^2. Parameters of procedure "plastic_zones" are n, Sy, Kini, Kfin and material, where n is the number of frames, Sy is the yield strength of material (in MPa), Kini and Kfin are the initial and final stress intensity factors (in MPa*m^1/2), respectively, which define the view frame.

Aircraft landing gear simulation and analysis
http://www.maplesoft.com/applications/view.aspx?SID=3782&ref=Feed
A computer aided graphical synthesis was undertaken to understand the kinematics of a nose wheel landing gear mechanism such as that on the Lockheed F16 using Working Model software. The mobility of the design was verified by computer animation. Computer modeling and finite element analysis are explored to analyze stresses developed while landing at normal sink rates. The deflections of the main spring gear are calculated and the internal stresses evaluated utilizing the finite element program Stardyne (Research Engineers, Inc.). The results of the modeling and simulation are discussed in this paper.

Metal forming process and mathematical modeling
http://www.maplesoft.com/applications/view.aspx?SID=3777&ref=Feed
The comparison of predictions from mathematical models and experimental data is one of the most important aspects of engineering analysis. In this worksheet we consider the process of pulling a metal rod through a cone shaped object (the dye). This process, called "drawing", is illustrated below and is one of the main forms of metalforming.

This worksheet demonstrates how Maple can be used to fit a circle to a set of datapoints. If a set of datapoints are known to lie on a circle, the average quadratic distance of the points from a circle should be minimized.

Welding 1: intersection of two pipes
http://www.maplesoft.com/applications/view.aspx?SID=3773&ref=Feed
This is a problem that arose from a consulting contract with the welding industry. The question is this: How does one control a robotic welding torch so that the welder follows precisely the joint between two cylindrical pipes? A typical pipe weld is pictured in the photograph in Fig. 1, where the joint between the two pipes is clearly seen to describe a closed curve. In the most general situation, the company must be able to form welds between pipes with differing crosssectional radius and arbitrary joint angle.
