MITCalc - Mechanical Engineering Calculations

Mechanical engineering calculations MITCalc 1.77 (1.76) were expanded and updated according to the current standards and reminders from users.

Friction brakes and clutches

The program is intended for the design, calculation and validation of four basic types of friction brakes and clutches. It also allows the user to determine the kinetic energy and loading moments of the mechanisms.

The program performs following tasks:

- Calculation of brake loads

- Calculation of clutch starting load

- Validation of a loaded clutch

- Design and validation of:

  - Disc brakes / clutches

  - Cone brakes / clutches

  - Drum brakes / clutches

  - Band brakes / clutches

- Calculation and temperature validation of the designed brake / clutch

The calculation uses data, procedures, algorithms and data from specialised literature, standards and company catalogues: [1] Clutches and Brakes Design and Selection; [2] Shigley’s Mechanical Engineering Design; [3] Textbook of Machine Design; [4] Brake Design and Safety; [5] Roloff / Matek – Maschinenelemente; VDI 2241-Blatt 1; VDI 2241-Blatt 2; SAE J866; SAE J661; Ortlinghaus; Goizper; TAROX; FERODO ...

Power Screw

The program is used to design and check power screws. It is used to solve the following tasks:
- Calculation of kinematic parameters (speed, torque, revolutions and power output...)

- Simple selection / definition of power screw (metric, square, trapezoidal...)

- Screw check for tensile/pressure, thrust, bend, buckling and critical revolutions.

- The program contains a table of materials, threads and friction coefficients.

- Support of 2D CAD systems.

The calculation uses data, procedures, algorithms and data from specialised literature, standards and company catalogues: [1] Mechanical engineering design; [2]Textbook of Machine Design, [3] Machinery’s Handbook 26th Edition; [4] ?ásti a mechanismy stroj?; ISO 68-1, 68-2, ISO 724, ISO 965, ISO 2904: 1977, DIN 513, CSN 01 4050, CSN 01 4052, ANSI/ACME B1.5-1977, ANSI/ACME B1.9-1973, ASME B1.1-2003, IS 4694-1968 ...

Ball Screws

The program is used to design, calculate and check ball screws. It is used to solve the following tasks:

- Preliminary design (minimum input parameters – sufficient to navigate and select from catalogs)

- Detailed analysis (load, dimensions, parameter check)

- Load spectrum table definition (speed, torque, revolutions and power output...)

- Calculation of an equivalent load

- Service life calculation, tolerances, temperature analysis

- Tensile/Pressure, thrust, bend, buckling and critical revolutions

- Lubrication proposal and efficiency calculation

- The program contains tables of screws according to ISO and ANSI

- Support of 2D CAD systems

The calculation uses data, procedures, algorithms and data from specialised literature, standards and company catalogues: ISO 3408-1:2006; ISO 3408-2: 1991; ISO 3408-3:2006; ISO 3408-4:2006; ISO 3408-5:2006; ISO 286-2:2010; DIN ISO 3408; JIS B1192-1997; JIS B1192-2018; DIN 69051-5; ANSI B5.48; THK, PMI, KSK, NSK, SKF, HIWIN, KURODA, NOOK, THOMSON, Steinmayer, MANESMAN ...

Thermal Properties of Materials

The workbook contains information defining the effect of temperature on some physical and mechanical properties of materials used in the engineering industry. It solves the following tasks:

- Calculation of the linear coefficient of thermal expansion and elongation of the component for the given heating process.

- Elongation of a group of components made of various materials arranged into a linear chain.

- Calculation of the modulus of elasticity for the given temperature.

- The database contains approximately 700 metallic materials used in mechanical engineering.

The calculation uses data, procedures, algorithms and data from specialised literature, standards and company catalogues: : EN 1561, EN 1563, EN 16079, EN 1753, EN 10088-1, EN 10095, EN 10269, EN 10302

Calculation extensions, modifications and updates:

Rolling Bearings – the possibility to calculate and compare the service life of an equivalent bearing supplied by another manufacturer has been added

Bolted Connection, Spring Calculations – refinement of the empirical model used in determining the physical properties of materials based on temperature; modification of additional calculation "Assembly parameters of the connection"

Welded Connections – redesign of calculation controls with the intention to improve workbook compatibility with different versions of MS Excel

Pinned Couplings – for some types of connection, the maximum permissible number of pins in the connection has been increased

Tolerance Analysis, Force Couplings of Shafts with Hubs – refinement of the empirical model used in determining the physical properties of materials based on temperature
