After the lightweighting of automotive cast steel parts, it can significantly improve the performance of automobiles in many aspects, which is mainly reflected in the following aspects:
Improvement of Power Performance:
The lightweighting of cast steel parts reduces the curb weight of the automobile, and the inertia of the vehicle decreases. With the engine power remaining unchanged, the resistance that the automobile needs to overcome during acceleration is reduced, enabling it to reach the expected speed more quickly, thus enhancing the acceleration performance of the automobile. In addition, the vehicle will start more briskly, and the driving responsiveness will be better.
Improvement of Fuel Economy:
According to the principle of energy conservation, a vehicle needs to overcome the resistance generated by its own weight during driving. After the automotive cast steel parts are lightweighted, the overall vehicle weight decreases, and the energy consumed during driving is reduced, resulting in an improvement in fuel efficiency. Studies have shown that for every 10% reduction in vehicle weight, fuel consumption can be reduced by 6% - 8%. This means that a lightweighted vehicle can save more fuel and reduce the operating cost for the same driving mileage.
Enhancement of Handling Performance:
Lightweighting lowers the center of gravity of the automobile, improving the stability of the vehicle. When turning, a lighter body can better respond to the driver's operation, reducing the roll phenomenon and enhancing the accuracy and flexibility of handling. At the same time, the load on the suspension system and the steering system is also reduced accordingly, making the operation of these systems easier and further optimizing the handling performance of the automobile.
Optimization of Braking Performance:
Due to the reduction in vehicle weight, the kinetic energy that needs to be overcome during braking is decreased, and the burden on the braking system is also reduced. This shortens the braking distance, making the braking effect more sensitive and reliable, and improving driving safety. In addition, lightweighting can also reduce the wear of the braking system and extend the service life of the braking components.
Improvement of NVH Performance:
After the lightweighting of cast steel parts, the vibration and noise generated during the vehicle's driving will also be reduced accordingly. On the one hand, a lighter body generates less impact when the road surface is uneven or during driving, reducing the transmission of vibration; on the other hand, the relative movement between components will also decrease due to the reduction in weight, thus reducing the generation of noise. This helps to improve the riding comfort inside the vehicle and create a quiet and stable environment for drivers and passengers.
Increase in Driving Range:
For electric vehicles, the lightweighting of cast steel parts can reduce the energy consumption of the battery. With the battery capacity remaining unchanged, the vehicle can travel a longer distance, increasing the driving range and reducing users' range anxiety. This is of great significance for the promotion and popularization of electric vehicles.
Improvement of Environmental Performance:
The improvement of the fuel economy of automobiles and the reduction of the curb weight directly lead to a decrease in exhaust emissions. Whether it is a traditional fuel vehicle or an electric vehicle, lightweighting helps to reduce the impact on the environment, conforms to the development trend of energy conservation and emission reduction, and makes contributions to environmental protection.
The lightweighting of automotive cast steel parts has a positive impact on various aspects of the automobile's performance, including power, fuel economy, handling, braking, NVH, driving range, and environmental protection. It is one of the important ways to improve the comprehensive performance of automobiles.
