MITCalc - Mechanical Engineering Calculations - Newsletter No. 24

Mechanical engineering calculations MITCalc 2.02 were expanded and updated according to the current standards and reminders from users.

Flywheels

The program is intended for a design of a flywheel, its analysis, and determination of dimensions. It also allows to solve a crank mechanism and to determine parameters of asynchronous motors.

The program solves:

- Design of a moment of inertia for a selected machine.

- Design of flywheel dimensions based on a required moment of inertia.

- Calculation of a moment of inertia based on dimensions of a flywheel.

- Calculation of a moment of inertia of masses with different revolutions (reduced moment of inertia).

- Calculation of a stress in rotating rings.

- Calculation of gyroscopic moment.

- Calculation of a moment of inertia from a load diagram and a required run unevenness.

- Calculation of coefficient of fluctuation of speed.

- Design of a flywheel in connection with a motor.

- Selection and calculation of parameters of approximately 1200 asynchronous electric motors.

- Crank mechanism solution.

The calculations use data, procedures, algorithms and information from literature, standards, and company catalogues.
