Introduction to the vehicles
cars. |
- The vehicle car, concept.
- Main requests of the vehicle car.
- The system man-machine-half.
- Objective and scope of the theory of the vehicles cars |
Interaction of the vehicle with the half. |
- Interaction between the vehicle and the surface of
rolling: general Characteristics and mechanics of the tyre, mechanical characteristics. Study of longitudinal efforts (traction, braked) and *trasversales (derive). Mathematical models.
- Aerodynamic of the cars: aerodynamic Actions on the solids, general concepts. Aerodynamic actions on the vehicle car. |
Analysis of the road infrastructure for cars and railways. |
- Influence of the road infrastructure in the dynamic behaviour of the vehicle |
Analysis of the longitudinal behaviour of the vehicle: traction and braked. |
- Dynamic longitudinal. Provision: Resistance to the movement. Fundamental equation of the longitudinal
movement. Tractive effort maximum limited by the *adherencia.
- Characteristic of the engine and transmission.
- Prediction of the provision of a vehicle.
- Braked of vehicles cars: Strengths and moments that act in the process of braked. Conditions imposed by the *adherencia: braked optimum. The process of braked. The system *ABS |
Analysis of the transversal behaviour of the vehicle and of the system of direction (lateral Dynamics of the vehicle) |
- Geometry of the direction.
- Manoeuvrability to low speed.
- Speed limit of *derrape and dump.
- Directional behaviour of the vehicle in
diet *estacionario. |
Analysis of the vertical behaviour of the vehicle and of the system of suspension. |
- The vibrations on the vehicle, action on the human being.
- The system of suspension: mathematical model.
- Cinematic of the suspension.
- Systems of suspension: elastic elements and of absorption.
- Influence of the suspension in the behaviour of the vehicle.
- Adjustments of the suspension. |
Systems of security in the vehicle. |
- Active and passive security.
- Systems of help to the driving: control of
traction and stability, *ABS.
- Influence of the technician of driving.
- The passive security: structures *deformables, cell of security, belts of security, *airbag. |
Reforms of importance in vehicles cars. |
- Normative and execution of reforms |
Rail material: *Bogies, cars, systems of braked and of traction, systems of suspension. |
- Infrastructure
- Systems of the rail vehicles: traction, suspension, etc.
