Disc Spring Solver intends to help the disc springs users to foresee the performances of the springs that they are using by giving them the possibility to make calculations using standard algorithms or new and more accurate algorithms and by offering options which are completely new compared to the other disc springs related softwares. One of these algorithms is the new Ferrari method that revealed how the standard method to verify if a reduced disc spring was dimensionally right was wrong, for more information look at the paper "A New Calculation Method for Belleville Disc Springs with Contact Flats and Reduced Thickness".
Disc Spring Solver can also suggest the best disc spring to meet the user's requests by combining more than 1000 different kinds of discs chosen from the included database.
Disc Spring Solver gives, for instance, first and, at today, only software of its field, the opportunity to create a spring stack with the desired design where the packets can be made with a different number and different kinds of disc springs and to consider the friction (and some other factors) effect during the foreseeing of the stack behaviour.
Moreover, the very intuitive user interface of Disc Spring Solver has been thought to give to the user the opportunity to set every calculation option in the main window and not in quite hidden child windows.
This is definitely the most complete disc spring software I have ever tried, I have used it in my applications (I am an engineer and I project sliding gates for ladles in steelplants) and its accuracy and being so easy to use are very useful for me
Maybe it is a little too expensive but I have seen the the new version is less expensive and anyway it costs less than the others.
I liked above all the possibility to design every kind of spring stack, above all stacks made with packets having a different number of springs. It is the only software I ever tried that allows this. The possibility of creating plots and 3D animations gave me the possibility. Moreover its accuracy in calculating performances as deflections under loads and so on (especially using its new algo "equivalent spring") gave me what I really needed for my work, as I said I project sliding gates for ladles in steelplants by I hae used it also for other applications and I have definitely recommended it to my collegues. I have also verified that what it is said on the site, in the CAD page, about the accuracy it is true, it gives me different values for the base angle and this is useful if you need to project a stack with packets having more than one spring.
