Assignment for performance of course work on ATO

Develop a detailed kinematic diagram of power distribution in the ATS transmission.

Perform design determination of engine power according to Leiderman's formula, plot the design external speed characteristic of ICE and the real one for the standard engine of the studied car (available from reference literature).

Carry out traction dynamic calculation of the car (according to the real external speed characteristic of ICE) with construction of dynamic characteristic, dynamic passport, acceleration graphs, fuel characteristic of steady-state motion and power balance.

Analyze the results obtained, formulate conclusions about the traction and dynamic capabilities of the car, about its fuel economy.

Give calculation of basic parameters of transmission, suspension, steering and braking units (in the scope given in the calculation example).

All drawings, graphs, tables, a list of literature and the text of the work are issued in computer form with compliance with the requirements of the NTTM department for the design of course works and projects.

Conclusion

The material presented in the work on the methodology for substantiating and evaluating the main operational properties of automobile base chassis seems to be sufficient to solve the engineering problem of choosing a transport base for the installation of various technological equipment in the construction industry.
