    ANSYS offers engineering simulation solution sets in engineering simulation that a design process requires. Companies in a wide variety of industries use ANSYS software. The tools put a virtual product through a rigorous testing procedure (such as crashing a car into a brick wall, or running for several years on a tarmac road) before it becomes a physical object. This pdf gives good start to understand and learn ANSYS

  4. Designing a machine or a product involving moving parts is common. This kind of design process requires performing motion simulation – also known as rigid body dynamics. Consider a classic Mechanics example of an elliptical trammel used to trace ellipses. A designer can define mates to perform assembly animation in a normal CAD program available today, to see how the components of the trammel mechanism move. However, the speed of the motion is irrelevant and timing is arbitrary in this case of assembly animation. In order to find velocities, accelerations, joint reactions, and other deta

  5. If there is any way you could co-op (work for a company who builds agricultural mechanization devices for several months each year) that would be most enlightening. I know a recent graduate of the university here who has already participated in exciting implementations and has several job offers to choose from. This is a wonderfully productive and growing profession.

    Machine Design Methods

    As an older engineer, I am rather dismayed by what I see as the results of engineering education today. I have seen most young engineers come out of their college degree programs with a modest familiarity with come CAD program and a related Finite Element program, and an almost complete lack of capability to analyze machine components without the use of FEA. Thus they are unfamilliar with basic design calculations relating shear stress in a shaft to the power being transmitted, the shaft sped and the shaft diameter. Instead, they want to create an FEA model and run the numbers that way which i

    Mine Hoist Problem, #54

    And just how would I do that, Timothy? 1)Do you want a video of the system (which only exists on paper at this time) and is therefore impossible to do? or 2) Do you want a video of me talking about the problem? What would be the point of that? the written words "hold still" and can be read and re-read as many times as necessary. What do you have in mind, Timothy? DrD

    Mine Hoist Problem, #54

    Well, here we are on 31 August with 151 views (presumable this first page only), and only 4 downloads (necessary to really see what the problem is). That is just slightly more than 2.5% of people bothering to actually look at the problem. How could this group be more lacking in curiosity? DrD

  9. James , You have identified in your own statement why no one is interested. You said, "one way is to do my project to make speed and torque increase that will violate a law of engineering and open many new doors for millions for all of history." No doubt many folks would like to open new doors and make history, but when you talk about violating the laws of engineering (physics), you are asking for the impossible. The laws of physics are not man-made laws that can easily be replaced with other man-made laws. Rather the laws of physics are the distillation of observed truth in the natu

    A COMPLETE INSTRUCTOR AND STUDENT SUPPLEMENT PACKAGE - Continued These ppts are set of instructor and student supplements. . A FOCUS ON DIAGNOSIS AND PROBLEM SOLVING The primary focus of these ppts is to satisfy the need for problem diagnosis. Time and again, the author has heard that technicians need more training in diagnostic procedures and skill development. To meet this need and to help illustrate how real problems are solved, diagnostic stories are included throughout. Each new topic covers the parts involved as well as their purpose, function, and operation, and how to tes

  11. Why not just do your own analysis and write your own code? This is cheap, gives you complete control, and let's you analyze any device you can understand. Take a look at my book, Mechanics of Machines, Ver. 2.1, available here at ME Forum without cost, for the way to do these things. DrD

  12. Hello, I am new to this and I'm looking for a program I can download to design a linkage system ( also if available, pulley, and gear system), input forces on the system and then get feedback on how much mechanical advantage is produced. Any guidance on this would be greatly appreciated as i've been searching for quite a while to no avail.

    one tooth gear

    James, your device looks more like a ratchet than a gear. Have you studied the principles of gearing? Your sketch just seems to bounce from one position to the next, whereas a gear controls the motion at all points in the tooth engagement. DrD

  18. This research study has been done in Aljabalein Power Plant at White Nile State. The objective of the study is to compare and differentiate between two types of fuel, light fuel oil (LFO) and crude oil (CRO) used in power plant situated in Aljabalein site. The comparison has been done on different viewpoints including the impact of exhaust gases on the surrounding environment, the performance of engines at different loads, and the operation and maintenance costs. It is found that CRO fuel oil is preferred to LFO fuel due to less operation costs. But it has many disadvantages such as hi

  28. If you're looking for top class rendering effects plus nice graphic designs then go for Solidworks. If you are looking for a simple, easy to learn software which widely used in industries then go for CATIA or Creo Parametric. But for simulations use ANSYS, its the best there is.
