MITCalc is a set of engineering, industrial, and technical calculations for your day-to-day routines. It will reliably, precisely, and most of all quickly guide you through the design of components, the solution of a technical problem, or a calculation of an engineering point without any significant need for expert knowledge.
MITCalc contains both design and check calculations of many common tasks, such as: spur gear, bevel gear, worm gear, planetary gearing, timing belt, v-belt and chain drives, bearings, springs, beam, buckling, shaft, bolt connection, shaft connection, force couplings of shafts, pins, tolerances, tolerance analysis, welded connection, technical formulas and many others. You also have available many material, comparison, and decision tables, including a system for the administration of resolved tasks.
Description in PDF format: English version, Persian (Farsi) version
MITCalc is an open system designed in Microsoft Excel to which you can make further modifications or user extensions without any programming skills.
You don't have to learn MITCalc because you already know how to use it. The straightforward and fully comprehensive user interface with complex on-line help and the "expert notes" system will allow you to be more productive in just a few minutes.
MITCalc supports simple interconnection of individual parts between either each other, or your calculation, or tables. You can easily customize a solution to any special task you need.
MITCalc cooperates with many 2D and 3D CAD systems (AutoCAD, AutoCAD LT, IntelliCAD, Autodesk Inventor, SolidWorks, SolidEdge, Pro/Engineer...). To draw a designed solution in 2D or insert correspondent 3D models and their assemblies is a matter of seconds.
Do you think you may be interested in MITCalc and you would like to try it? You don't need to wait! Download it right here (30-day evaluation). We truly believe that MITCalc will be a fundamental tool in everyday process of solving your technical tasks.
The calculation is intended for the purposes of geometric and strength designs of helical compression cylindrical
springs made of wires and rods of circular sections, loaded with static or fatigue loading. Application is
developed in MS Excel, is multi-language, supports Imperial and Metric units and solves the following main tasks:
- Automatic design of a spring.
- Selection of an optimal alternative of spring design in view of strength, geometry and weight.
- Static and dynamic strength check.
- Support for Cold formed springs and Hot formed springs
- Calculation of working forces of a spring of known production and installation dimensions.
- Calculation of installation dimensions for known loading and production parameters of the spring.
- The software includes a table of commonly used spring materials according to ISO, ASTM/SAE, DIN, BS, JIS
and others.
- Support of 2D CAD (AutoCAD, AutoCAD LT, IntelliCAD, Ashlar Graphite, TurboCAD) and 3D CAD in full
calculation package (Autodesk Inventor, SolidWorks, SolidEdge, Pro/E).
The calculation is based on data, procedures, algorithms and data from specialized literature and standards EN
13906-1, DIN 2089-1, DIN 2095, DIN 2096.This module is a part of MITCalc - Mechanical and Technical
Calculation Package for gear, belt and chain drives, springs, beam, shaft, bolt connection, shaft connection,
tolerances and many others.
