Create algebraic function using a numeric dsolve solution

XelN4g4 — Sat, 27 Apr 2013 09:51:23 Z

Hello,

for my mechanical engineering studies we have to optimize an engine during a workshop. Therefore we have to use a numerical dsolve to solve the equation of motion. I have to get the maximum bearing reaction for a constant rpm. In order to get this I can't think of anything else but use the dsolve solution and use it in maximize.

ysk_2 := t -> -rc*cos(phi(t))-lp*cos(alpha(t))-lkb-y(t);
ysp_2 := t -> -rc*cos(phi(t))-lp2*cos(alpha(t))-y(t);

Entering reference values in tables

9colai — Thu, 28 Feb 2013 14:57:45 Z

Hi!

I just started using Maple for my engineering study some weeks ago, i have had luck finding help by google and forums so far. But now i ran into the first problem i can't find any answers for.

I want to add some values in a table like you can in excel. The values have to change like everything else in the document when then references changes and

MapleSim 6: Advances in System-Level Modeling

Laurent Bernardin — Tue, 04 Sep 2012 16:37:14 Z

MapleSim has seen a rapid evolution since its inception in 2008 as a multi-domain system-level modeling and simulation environment. Market response has been outstanding: Maplesoft has been working with an expanding list of key industry players such as AISIN AW Co., Ltd. and B&R, while major customers like

NASA Jet Propulsion Laboratory to Land Rover on Mars on Monday

Paul Goossens — Fri, 03 Aug 2012 19:45:04 Z

On Monday, August 6 at 1:31 a.m. EDT, NASA will attempt the landing of a new planetary rover, named Curiosity, on the surface of Mars. The Mars Science Laboratory project is managed by the NASA Jet Propulsion Laboratory (JPL) in Pasadena, California, a world-renowned center for robotic space exploration and advanced science and engineering. JPL recently began a widespread adoption of Maplesoft technology, and Maplesoft’s products are expected to help JPL save...

Extension of getdata

Markiyan Hirnyk — Tue, 03 Apr 2012 14:44:31 Z

Starting from Maple 15, the useful ?plottools/getdata command is added. It tansforms a Maple plot to a Matrix. Unfortunately, the getdata command deals only with Maple plots. The question arises: "How to get a data from bmp, jpg, tiff, pcx, gif, png and wmf formats?" This is used in medicine and engineering. Such question was asked here

Displaying calculations

trosenberger — Fri, 02 Dec 2011 16:07:47 Z

I have been using Maple in Document mode to provide documentation of engineering calculations according to various design standards.

I have been asked to provide more detail about certain critical calculations.

Ideally, I would want to enter the formula as a symbolic espression, then the output would begin with and echo of the expression with numberic values substituted for the variable names (ie without performing any mathematical operations), and then give the evaluated answer.

New Generation CAE system for framed structures based on Maple

S.Arlou — Mon, 19 Sep 2011 16:32:08 Z

It would be good I hope to present symbolic-numeric CAE system for framed structures analysis.

It will be available soon as Preview version for enthusiasts

The main features are:

One calculation act - all analytical dependencies.
Fast designing process for structural systems in industry, consulting and design companies;
Fastest parametric analysis of construction. New quality of designing in optimization tasks,...

First Workshop on Undergraduate Engineering Education with MapleSim

Sun, 15 Aug 2010 21:05:46 Z

On Tuesday August 10, 2010, the first meeting of an ad hoc group focused on exploring the use of MapleSim in the engineering curriculum met at McMaster University, Hamilton, Ontario, Canada. Faculty from McMaster University, Kettering University, Lawrence Technical University, University of Waterloo, Ryerson University, University of Ontario Inst. of Technology, and the State University of New York (Buffalo and Binghamton).

The full-day workshop provided an ideal...

How to create a spectrum of colors in contourplot?

Hamidreza — Thu, 24 Jun 2010 08:11:42 Z

Hi friends,

I am using contourplot / contourplot3d for a function f(x,y). But the coloring accepts only two colors whereas I want to get a contour like the one which is shown here and is more common in most engineering applications.

My second question is how I can change the size of the plotted graph, because I am using the results in a report, so I need to have a better resolution.

Thank you!

how to improve simulation efficitioncy with kinematic loop mechanical model?

wander — Mon, 14 Jun 2010 02:39:54 Z

Current I need model a mechanical system with kinematic loop. In Maplesim4 the calculation speed is too slow. I need to use this model in HILS. How to solve this problem? I check the 'four bar' example, It's too slow(simulation 1 second, 40second is needed, Intel xeon 3GHz,2cpu) Anyone who can help me? Thanks! Wander

There is something profoundly satisfying when something that goes “viral” on the Web has some connection to your life. This happened recently when I and my colleagues were pointed towards a video of some laboratory robots that somehow drew almost a million views on YouTube alone. For an engineer,...

An “Animated” Conversation

Stephanie Rozek — Thu, 20 Aug 2009 04:00:00 Z

This week I decided to do some research and find out the details of how to make model animations with MapleSim, by adding in CAD drawing files of the component parts. To see what I mean, take a look at this quick animated movie that shows a robot arm with five degrees of freedom:
