Study Notes
Vehicle Dynamics and Design
- The main motive force for most vehicles is the longitudinal force generated by the powertrain.
Forces Opposing Motion
- Forces that oppose the motion of a vehicle include rolling resistance, aerodynamic drag, and gravity.
Importance of Vehicle Dynamics Modeling
- Vehicle dynamics modeling is an integral part of vehicle design, as it helps to understand the behavior of the vehicle under various operating conditions.
Designing Complex Systems
- When designing a complex system like an electric vehicle, a system-level approach is generally taken, focusing on the integration of multiple components and subsystems.
Electric Motor Rating
- The engineering discipline that typically focuses on understanding the rating of the motor in an electric vehicle is electrical engineering.
Component Level Design
- The purpose of component level design in electric vehicles is to optimize the performance of individual components, such as the motor and battery.
Lateral Vehicle Dynamics
- Understanding lateral vehicle dynamics is crucial in vehicle modeling when the vehicle is cornering, braking, or accelerating, as it affects the vehicle's stability and handling.
IC Engine Dynamics
- Longitudinal dynamics are primarily needed to control a normal IC engine-based vehicle.
Electric Drive Trains
- Understanding both longitudinal and lateral dynamics is important for electric drive trains in dual motor systems, as it enables the optimization of traction, stability, and handling.
Vehicle Design Requirements
- In the early stages of vehicle design, designers try to understand the broad requirements the vehicle needs to deliver, including performance, efficiency, and safety.
System Level Design Factors
- Key factors that need to be understood during system level design of a vehicle include the interaction between components, the impact of component design on overall system performance, and the integration of control systems.
Lateral Vehicle Dynamics in Operation
- Vehicles that primarily operate based on lateral vehicle dynamics are those that involve high-speed cornering, such as racing cars.
