![]() Trebuchet Simulator - Engineering Analysis and Simulation software that works realiably and quickly. Free download. Trebuchet simulator capturing all. And if you wish to build a trebuchet yourself, this trebuchet software program allows you to optimize. And then download the. Trebuchet Simulator To aid designers and enthusiasts (and anyone who wants to win a trebuchet competition), I created a trebuchet simulator, programmed in Microsoft Excel which simulates the motion of a trebuchet, and is very useful for trebuchet design. It captures all the essential. And if you wish to build a trebuchet yourself, this trebuchet software program allows you to optimize the dimensions of your trebuchet for maximum throwing distance, and also allows you to determine the required finger angle which results in the trebuchet releasing the payload at the right time, for maximum throwing distance. The required finger angle is based on the friction between the finger and ring. See the link above for an explanation of finger angle and ring. A user manual in PDF format is included with the Excel program. The simulator is straightforward to use and since it is programmed in Excel the design data is displayed automatically in charts, for easy reference. The figure below shows an example of a chart in the Excel spreadsheet, which shows range (throwing distance) as a function of release time. Below is a screen capture of the Excel spreadsheet. With the simulator you can also: • Choose whether or not to use a guide chute. • Calculate sling tension, and the reaction forces at the fixed pivot location of the beam (to which the sling and counterweight is attached). Accurately predicting the motion of a trebuchet requires a lot of complicated mathematics. Having a software program, like this simulator, will save you a lot of work. All the files that come with this trebuchet simulator are contained in a single (compressed) file, in the 'zip' format. This file is 2.4 MB in size. You need to uncompress this file before you can access it. Ashtech downloads. To use the trebuchet simulator program you need to have Microsoft Excel installed on your computer. ![]() The program is compatible with all versions of Excel. The cost of the Excel program plus manual is $7.95 USD, and is payable through PayPal. To purchase, click on the link. This will open another browser window, which will take you to the PayPal site. From there you can enter your purchase information, and then download the product. Support is available if you have any questions or need assistance with anything. You may email me via my. My alternate email address is:. If possible, write me with the same email address that you entered in the purchase form. This isn't necessary but it just makes it easier for me to confirm that you actually purchased the product. If you didn't purchase the product your support questions will go unanswered. Since the simulator cannot be returned after it is downloaded, refunds (if requested) will be determined on a case by case basis. There are several simulators around, mostly for trebuchets. Atreb and Fat Sim is considered to be the most accurate simulator, and is a very powerful tool. It does have a limited demo, but it is very limited. Is basically the same thing for. They are both Windows only. Both run OK, however, under Windows emulators for Mac. VirtualTrebuchet is a free online simulator. It simulates. It is easy to use, and gives accurate results. It is a web application with no download required. TrebStar has both Mac and Windows versions. It is very easy to use, and the demo is quite functional. It can simulate basic, though it can be forced to simulate. It does not include friction so it will always overestimate range, but is great for optimizing dimensions. The free app is fully functional with no features disabled, as of Feb. The very first (1998) simulator with a sliding projectile phase! Working Model One of the more general purpose ones is. It has a free demo that does not allow saving, and is quite expensive. The demo can be useful, and was used by Chris G when he invented the. It can handle pretty much any design, but is much harder to use. There is a somewhat recent Windows version, and a really old Mac version. Algodoo (Was named Phun) is a completely free general purpose physics simulator (like working model). It is easy to use, and very modern, however it is harder to make things like slings and timed releases in Algodoo than working model.
