    Catia V6 PKM Express Installation

    I am planning to buy 10 licenses of CATIA V6 PLM Express Academia for my university. I am wondering how hard the installation is. The OS is windows server 2008. Could the installation be done by someone who is not an IT expert? I was warned by a friend of mine that this installation needs...

    Precast plants layouts

    Dear all, I am looking for an information source "book, website, report, etc.." that helps me in designing a layout for a precast concrete plant whether “circulation or stationary”. Based on my knowledge, I see that that the layout design depends on the types of elements produced, plant...

    Compression spring selection

    Thanks a lot guys. The best thing is to redesign the device so that there is enough space for the springs.

    Compression spring selection

    Ok. Thanks. But Can the high stress problem be solved if the force is reduced to 100N instead of 150N at a height of 17mm. Or what is the highest force that can be achieved at a hieght of 17 mm.

    Compression spring selection

    Thank you. Now I can say that you know exactly what I am looking for. Basically, I was looking for a spring with a stiffness of 30 N/mm but I was unable to find it in any of the catalogues. As for me, it seems to be impossible from a scientific point of view to have such spring with a...

    Compression spring selection

    Thank you all for your response. I am sorry if my explanation is not clear enough. Anyway, the procedure that I described is repeated twice a day and the device should serve for around three years which means more than thousand cycles. To reiterate, the problem is: I need a spring that can be...

    Compression spring selection

    The spring is for dynamic loading. To answer your second question: The spring is imbedded inside a device that is attached to the ground. In this case, the spring is initially compressed to a length of 12 mm. At this point; the spring force is not an issue. In other words, the spring force is...

    Compression spring selection

    I am looking for a compression spring that has the following specifications: Initial length: 22-23 mm The spring will be compressed to a length of 13-14 mm. The force when the deflection is 5 mm should equal or exceed 150 N (let’s say if the initial length is 22 mm, the force at a length of 17...
