The new car comes standard with wipers. Which is better, boneless or boneless?

Many people are discussing who is better to use the boneless wiper or the boned wiper. But if it were me, I would recommend you to choose the boneless wiper. Boneless wipers have higher wiping efficiency and better driving sight.

At 1 point, the wiping efficiency of boneless wiper is much better than that of boned wiper, and the driving sight will be better in rainy days.

There are many gaps between the skeleton of the bone wiper and the rubber strip, and the rainwater will flow directly to the glass through these gaps, so that the rainwater will not be cleaned. The boneless wiper strip and the skeleton are a whole, which can avoid similar situations. In addition, the boneless wiper exerts downward pressure through a whole piece of steel sheet, so that the rubber strip is uniformly stressed, and the curved windshield is more closely attached, and it is not easy to be scraped.

Jianghuai Automobile Shao Gang published 1 paper "Design of Automobile Wiper Blade", and compared the pressure distribution of two types of wipers. You can see the wiper with bones. Because the pressure is high where there are supporting points and low where there are no supporting points, its pressure distribution fluctuates obviously. But the pressure distribution of boneless wipers looks like a smooth curve.

Second, boneless wipers are quieter to use.

There is a gap between the metal bracket of the bone scraper and rubber strip. When the car is driving at high speed, the airflow passes through these gaps quickly, which will produce obvious wind noise and even cause jitter.

But boneless wipers are often designed according to aerodynamic principles. Ran Yan of Hunan University has a master's thesis on the design and optimization of automobile wiper system. He did a simulation experiment, and the results showed that the hollowed-out area of the boneless wiper on the back was significantly lower than that of the boneless wiper.

Speaking of people, it means that the wind resistance is lower, the noise is not so big, and the probability of wiper jitter is smaller.

Third, the shortcomings of boneless wipers have little impact on family cars.

The main disadvantage of boneless wiper is that the durability is a little worse due to the cancellation of the metal bracket, and the cleaning effect on some big dirt on the windshield is not so good. Imagine that the wipers of this family car are basically scraping dirty things such as rain, dust and bird droppings, and there are few big stains.

Moreover, the wiper itself is a wearing part and needs to be replaced regularly. If you use a boneless wiper, change it 1 year or so 1 time, which is actually quite durable. On the other hand, the durability of bone wipers is better, but the wiping efficiency is low and the noise will be more obvious, which directly affects our car experience.

So this is also the reason why new cars basically like to use boneless wipers when they leave the factory. The durability of boneless wipers is very important. However, when choosing a wiper, you also need to pay attention to the place, and you should focus on the steel sheet inside. Boneless wipers mainly rely on steel sheets to disperse pressure, just like the foundation of the whole house. If the quality is too poor, it may be deformed and straightened in a few months.

As a result, the adhesive tape could not get enough downward pressure, and it could not fit the glass well, so it was scraped clean. For example, some friends think that the durability of boneless wipers is much worse than that of boneless wipers, probably because they bought steel sheets.

To avoid this situation, it depends on what material the steel plate is made of. High carbon steel is relatively better.

Compared with ordinary carbon steel, the content of nonmetallic impurities such as sulfur and phosphorus is much lower, and the comprehensive mechanical properties will be better, and the steel plate is not so easy to deform when used.
