What do you think of the car’s beams: Analysis of hot topics on the Internet in the past 10 days

In the automotive field, the car's frame (frame) is an important part of the vehicle structure, which directly affects safety and durability. Recently, there has been a heated discussion on the entire Internet around "how to look at the car's beams", involving purchasing tips, material analysis, maintenance precautions, etc. This article will combine the hot content of the past 10 days and provide you with a detailed analysis through structured data.

1. Comparison of core parameters of car beams (popular model data)

2. Recent hot topics of discussion

1.New energy vehicle backbone changes: With the popularity of electric vehicles, battery pack-integrated frames have become a new trend. The one-piece die-casting technology of Tesla Cybertruck has caused widespread controversy, and some users are worried about maintenance costs.

2.Off-road vehicle beam review: Under the topic #Hardcore Off-Road Challenge on the Douyin platform, the video comparing the performance of the girder of various models in extreme road conditions has been played more than 80 million times, among which the torsional stiffness test of the Great Wall Tank 300 has attracted the most attention.

3.Used car appraisal skills: Xiaohongshu’s tutorial “3 steps to determine whether a beam has been repaired” received 120,000 favorites, with key mentions:

• Check solder joint uniformity
• Measure the thickness of key parts
• Observe the status of anti-rust coating

3. The five major issues that users are most concerned about

4. Professional advice

1.Key points to check when buying a car: It is recommended to carry a strong flashlight to check the joints of the beams, paying special attention to the condition of the chassis armor coverage area. The recent "hidden welding" incident of a certain brand reminds consumers to check maintenance records.

2.Material Selection Guide: It is recommended to choose galvanized steel plate girders in extreme climate areas, while coastal areas need to focus on anti-rust technology. The latest industry data shows that laser tailor welding technology can reduce the weight of girders by 15% while increasing their strength.

3.Precautions for modification: The traffic control department has recently strengthened its investigation and punishment of illegal modifications of beams. If you need to install equipment such as a roll cage, the integrity of the original structural parts must be retained and the change must be registered.

5. Forecast of future trends

According to the latest technology roadmap of the Ministry of Industry and Information Technology, beam collision energy absorption standards will be mandatory from 2025. BMW and other car companies have begun testing carbon fiber composite beams, and the cost is expected to be 40% lower than existing solutions. At the same time, a concept car of smart girders (with stress sensing system) has been unveiled at the CES exhibition, which can monitor the structural health status in real time.

From the above analysis, it can be seen that the selection and maintenance of vehicle beams need to comprehensively consider multiple factors such as material, technology, and usage scenarios. It is recommended that consumers continue to pay attention to the crash test reports issued by authoritative organizations and conduct professional chassis inspections regularly.
