Where can the lightweighting of new energy vehicles be carried out?

If you want to make cars lightweight, there are three main ways: apply high-strength and lightweight.Materials (means), such as high-strength steel, ultra-high-strength steel plate, aluminum alloy, magnesium alloy, engineering plastics and fiber-reinforced composite materials, etc.

The body adopts steel plate stamping and welding to improve the remote performance of small cars. If you consider the slightly heavy inside the car, you can cancel the modification of the front wheel stamping parts.

Car lightweighting is to reduce the maintenance quality of cars as much as possible under the premise of ensuring the strength and safety factor of cars, thereby improving the dynesm of cars, shortening fuel consumption and reducing exhaust pollution. Experiments show that if the quality of the car is halved, the fuel consumption will also be reduced by nearly half.

Generally speaking, there are three ways to achieve the lightweight of the car body: one is to apply high-strength lightweight materials; the second is to optimize the body structure; and the third is to apply advanced manufacturing technology. What are the methods and techniques for lightweighting cars?——The choice of lightweight materials reduces the thickness of the board and improves the materials.

And the best way to realize the lightweighting of new energy vehicles is to use carbon fiber materials reasonably. Experiments show that using carbon fiber material to replace the existing steel body can effectively reduce the weight by more than 60%, and the range can be increased by more than 20%.

To realize the lightweighting of new energy vehicles, first of all, strive to achieve structural lightweighting when designing. Not only the body frame, but also the lightweighting of the chassis and other parts can be realized by adopting the structural lightweighting design concept. The second is to lighten the body. For new energy models, battery weight accounts for a large part of the total weight.

1. To realize the lightweighting of new energy vehicles, first of all, strive to achieve structural lightweighting when designing. Not only the body frame, but also the lightweighting of the chassis and other parts can be realized by adopting the structural lightweighting design concept. The second is to lighten the body. For new energy models, battery weight accounts for a large part of the total weight.

2. The key to the lightweighting of new energy vehicles is to reduce the total weight of the body and improve energy efficiency, so as to increase the range of the battery and reduce the energy consumption of the vehicle.

3. New energy lightweighting refers to a technology that uses new energy technology and lightweight material technology to reduce the weight of automobiles, electric vehicles, aircraft and other vehicles and improve their energy utilization rate. Lightweighting can reduceIt reduces the energy consumption and emissions of vehicles, improves the maneuverability, acceleration and safety performance of the car, and extends its service life.

4. First of all, lightweight design aims to reduce the overall weight of the car and put forward higher requirements for fasteners by replacing traditional metal parts with lightweight materials.

What are the lightweight materials for automobiles

The most common alloy materials in automobiles are aluminum alloy and magnesium alloy. Among them, aluminum alloy is currently the most widely used and common lightweight material for automobiles. Research shows that aluminum alloy can be used for a maximum of 540kg vehicles. In this case, the weight of the car will be reduced by 40%. Audi, Toyota and other all-aluminum bodies are good examples.

Aluminum alloy: The density of aluminum is about one-third of that of steel, which is the most widely used lightweight material.

If you want to achieve the lightweighting of automobiles, there are three main ways: the application of high-strength and lightweight materials (means), such as high-strength steel, ultra-high-strength steel plates, aluminum alloys, magnesium alloys, engineering plastics and fiber-reinforced composite materials, etc.

Among them, aluminum alloy is the most widely used and common lightweight material for automobiles at this stage. Studies have shown that aluminum alloy can be used up to 540kg in the whole vehicle, in which case the car will lose weight by 40%. The all-aluminum body of Audi, Toyota, etc. is a good example.

Lightweight materials include aluminum alloy, magnesium alloy, carbon fiber, etc. These materials have low density and high strength, stiffness and other properties, which can reduce the weight of the car while ensuring the performance of the car. For example, replacing steel with aluminum alloy can reduce the weight of the car by about 30%.
