How to learn car dynamics? What foundation do you need?

1. Understand the basic knowledge: You need to understand some basic knowledge, such as the basic structure, working principle, performance indicators, etc. of the car. These basic knowledge can be obtained by reading relevant books, watching video tutorials or taking relevant courses.

2. Master the development history of fluid dynamics, cultivate your deep interest, and only when you are interested will you have the driving force for active learning. Mathematics must be used in dynamics, so mathematics is very basic and must be learned well! Liquid dynamics is a branch of dynamics, and it is also very important to learn Newton's laws of motion well.

3. Master certain basic knowledge. Including basic knowledge of English, basic knowledge of mathematics, basic knowledge of computer, and relevant knowledge of employment and entrepreneurship. ( 2) Understand and master the relevant professional basic knowledge. Including the basic knowledge of electrical structure, automobile structure, etc. ( 3) Master the relevant professional and technical knowledge.

4. If you want to master the professional knowledge of automobiles, you must first carefully study basic theories, such as mechanical principles, electronics, automotive dynamics, automotive electrical science, automotive manufacturing technology, etc. These theories are the foundation of all automobile expertise. Only a solid theoretical foundation can play the greatest role in practical application.

5. A car is a non-track frameless vehicle driven by its own power device and has 4 or more wheels.In terms of its design and technical characteristics, passenger cars are mainly used to carry passengers and their carry-on luggage and/or temporary items, including the driver's seat, and the passenger car has no more than 9 seats.

6. Basic knowledge: higher mathematics, university physics, electrical technology, fluid mechanics, thermal energy, etc. Vehicle engineering expertise: (1) Automotive dynamics: Study the physical problems of automotive powertrains, including the structure, principle and performance of various parts of automotive power systems. Mechanical dynamics, higher mechanics, mechanics and other related knowledge.

Introduction to the content of vehicle system dynamics

1. The content of "Automotive Dynamics (4th Edition)" includes: overview; Chapter A: Drive and braking; Article B: Vehicle vibration;Chapter C: The stability of driving. The 4th edition adds relevant content to improve the safety and comfort of vehicles due to the development of sensing technology, electronic technology, mechanical and electronic technology, etc.

2. The main content is divided into: introduction, vehicle acceleration performance, braking performance, aerodynamics and rolling durability, driving control, stable state design, vehicle flipping, driving system, fatigue design, suspension system.

3. The automobile power system refers to the process of transferring the power generated by the engine through a series of power transmission and finally to the whole mechanical arrangement of the wheels.

4. In addition to introducing the basic theory of vehicle dynamics modeling, tire mechanics and the basics of automobile aerodynamics, this book focuses on the automobile engine, transmissionThe driving dynamics and braking dynamics affected by the dynamic system and braking system, as well as the content of driving dynamics and maneuvering dynamics.

5. This book provides a comprehensive summary of automotive dynamics. The book introduces the active system as the standard configuration of the vehicle into the basic theory of drive and braking, vibration and control stability. It also discusses the theoretical problem of the whole vehicle driving when the vehicle is disturbed, and also takes into account the interaction between the vehicle and the driver.

Introduction to the dynamics of the automobile system

The principle of dynamics: The automobile engine drives the automobile forward through internal movement, so it involves the principle of dynamics. The piston, crankshaft and other components inside the engine will generate kinetic energy and potential energy during movement, which will be transmitted to the car and push the car forward.

Car wind tunnel is a large-scale experimental equipment used to study automobile aerodynamics. It is a pipeline used to generate artificial airflow. BMW Company is familiar with it. It has two wind tunnel equipment, one is used to test 1 to 2 car models and the other is used to test 1 to 1 car models. .

In addition to introducing the basic theory of vehicle dynamics modeling, tire mechanics and the basics of automobile aerodynamics, this book focuses on the driving dynamics and braking dynamics affected by automobile engines, transmission systems and braking systems, as well as driving dynamics and maneuvering dynamics.

The front downward pressure refers to the installation of large enclosure and other ancillary devices at the front of the car to guide the airflow and thus obtain the downward airflow pressure. The rear pressure generally refers to the downward pressure caused by the airflow caused by the tail during high-speed driving.The forward and downward pressure in automobile dynamics refers to the resistance of air acting on the downward movement of the automobile when the automobile moves forward.

Aerodynamics, simply put, is the various external forces subjected to by the object in the air or any fluid, and the appearance or shape of the object is modified according to the data obtained in the experimental test to meet the characteristics that people need.

The content of Automobile Dynamics (4th Edition) includes: Overview; Chapter A: Drive and Braking; Chapter B: Vehicle Vibration; Chapter C: Driving Stability. The 4th edition adds relevant content to improve the safety and comfort of vehicles due to the development of sensing technology, electronic technology, mechanical and electronic technology, etc.
