Automotive Black Technology Chapter 750: : Fight against difficulties!
www.lnmao.org, the fastest update to the latest chapter of automotive black technology!
After the launch of the "Atlas" project, Li Fanyu became a busy spinning top.
Zhengxin’s R&D team has been divided into four parts; the F750 R&D team with OEM as the main body, the heavy fire truck universal platform R&D team led by Liu Qing, the ladder, elevated platform and elevated spray arm led by Wang Yu project team, as well as the hydraulic remote control/control system research and development team led by Xu Fufang himself.
After the project was launched, the entire R&D center was busy. In desperation, Li Fanyu had to invite Professor Zhang, who had been in poor health some time ago and had been recuperating at home for more than two months, to come back and be responsible for the coordination and deployment of the four teams.
The old man's health will actually be better after the new year, but his three proud disciples are now able to stand alone, and his originally ineffective disciple has become a business tycoon that is stirring up China's automobile industry.
As a human teacher, Lao Zhang is already satisfied with seeing this result in his sixtieth year. So after I recovered, I didn’t rush to go to work. Instead, I took leave from the group and took Li Fanyu’s wife to Qiongya for vacation.
After Li Fanyu called and explained the current situation of the R&D center, the old man flew back without saying a word.
With Lao Zhang taking charge of the central coordination, Li Fanyu's burden is lighter. But the workload is still overwhelming.
Because this research and development project was too large, Li Fanyu personally served as the chief engineer of the "Atlas" project.
The research and development tasks of the four parts are not simple, not to mention that the firefighting platform and firefighting jacket are areas that Zhengxin has never been involved in, and many things require his own hands.
In order to save time, he had already completed the F750 drawings while waiting for the OEM engineering team to come to China. So after little Culbo and others arrived, he started research and development work with them. In order to ensure that he could escape quickly, Li Fanyu spent three days and three nights explaining the important points of the F750.
The OEM branch has been responsible for the specific work of the F150 since it was reorganized into Zhengxin. As the first and only model produced by Zhengxin in the North American market, the OEM's engineering team's understanding of this model is simply ingrained in their bones.
The similar structure of F750 and F150 makes engineers familiar with it. If not, Li Fanyu would not be able to leave in a short time no matter what.
After explaining all the key points and letting the OEM engineers understand them, Li Fanyu, who was freed from here, started working on the design of a universal platform with Liu Qing's team.
In fact, it is not difficult to independently develop a top-mounted platform that can carry ladders, elevating spray arms and climbing platforms. It is nothing more than good weight distribution, reasonable use of materials and reasonable layout of the upper part of the axle, so that it can support the weight and working status of the upper body machinery.
But who made Li Fanyu’s request special?
The difficulty in the design and development of Zhengxin's heavy-duty fire truck universal platform is how to perfectly integrate these three heavy-duty fire truck models!
If it is special-purpose, then the design engineers can combine the platform with the upper body and carry out a little bit of climbing design starting from the basics.
But if it is to be "universal", it is too complicated.
How do you describe this feeling?
It's like cracking a combination lock.
A dedicated fire protection platform is like a three-digit password lock; ten numbers from 0 to 9, using a stupid method, that is, entering the password one by one starting from 000 to 999, is nothing more than 10x10x10, which is a thousand password combinations That’s all. If you are lucky, for example, if you encounter a password like 099, you may only need to fumble ninety-nine times to succeed.
But to achieve the purpose of "universal", it is undoubtedly equivalent to adding another English character to this combination lock, turning it into a four-digit mixed combination lock.
The complexity immediately changed from 10X10X10 to 62X62X62X62! The original thousand combinations have been upgraded to tens of millions.
Li Fanyu was also helpless, the goal he set was indeed too big,
But looking at the market, things that are not difficult are often accompanied by an outrageously low price. It doesn’t matter if you don’t understand this, just take a look at Yiwu Small Commodity Market.
But things with high technical content are often accompanied by huge value and added value.
Take a very common item as an example; it is also a lighter, the kind of disposable advertising lighter that the hotel gives away when eating, and the price is only one yuan. But an ordinary Zippo, which is windproof and cold-proof and can look cool, can often sell for two to three hundred.
This is the gap.
For huge profits and huge market competitiveness, fighting against difficulties should be an essential quality for every technology-based enterprise.
Obviously, Zhengxin and Li Fanyu are together.
And what Li Fanyu has is not only the courage to risk everything - he also has design expertise.
After studying a large amount of information on foreign heavy-duty fire truck mounting platforms, he found inspiration in the SAU-54654 Russian-made fire ladder that was designed in this time and space but was not in service.
In fact, the platform of the SAU-54654 fire ladder truck is not advanced, and this fire truck is an airport light fire ladder truck for airport rescue.
But in order to meet the airport fire rescue mission to the greatest extent, this ladder truck uses a telescopic working platform that looks very lame. Obviously, this is a complete failure for the SAU-54654 fire truck, and it has been widely criticized by the airport fire department.
But where to put things and when to put them. When Li Fanyu saw this telescopic design, he felt like he had found a treasure.
The telescopic principle is definitely in line with the plan he envisioned.
After an intense discussion with Liu Qing and others that was almost quarrelsome, the design direction was decided.
In order to meet the needs of ladders of different heights, there are two different types of tops: ascending platforms and elevated jet arms. Inspired by the SAU-54654 airport fire truck loading platform, Li Fanyu proposed the concept of a modular multi-purpose platform with telescopic slide rails combined with a turntable.
Normal heavy fire truck upper parts are fixed on the axle to obtain a stronger mechanical bottom, a simpler control system structure and the most suitable mechanical support points. However, the inevitable result of such a design is that the Yitai chassis can only carry one top.
With the complexity of urban buildings, there are countless environments where fires can occur. Many times, a dedicated car is required.
But the problem is that usually in urban fires, ladders and climbing platforms are rarely used at the same time.
It can be seen from the functions between the two; the purpose of the climbing platform is to transport people and rescue supplies to high altitudes, rescue trapped people and spray fire extinguishing agents,
The purpose of the ladder is exactly the same as this. It can be said that the performance and functions of the two heavy-duty fire-fighting aerial vehicles overlap to a large extent.
If a fire department has a ladder, there will be no need for a climbing platform to a large extent.
So with a ladder, does it mean we don’t have to climb a high platform?
No!
The complexity of the fire location determines the necessity of the existence of any kind of fire-fighting equipment. The ladder is vertically telescopic and cannot be turned from the middle part. Therefore, when encountering situations where firefighters need to enter at an angle, or where special angles are used to direct fire extinguishing agent injection, a climbing platform with adjustable telescopic angle or orientation must be used.
You may not need it, but you must have it. This is a very contradictory issue in the field of equipment required for modern firefighting operations.
The modular universal platform designed by Li Fanyu exists to solve such problems!
According to the design concept of telescopic slide rails combined with turntables, if the design is feasible, then this platform can be used to carry ladders of different heights, ascending platforms of different heights and elevated spray arms of different heights! It only takes a very short time to complete the switch between three types of tops on a heavy fire truck chassis.
In this way, one car can be used for multiple purposes!
What does this mean?
This means that after a fire occurs, firefighters can freely choose which jacket to load based on the specific conditions coming from the front! This means that you only need to equip a firefighting jacket, without having to equip a tow truck! This means that purchasing costs and maintenance costs are greatly reduced! This means that the fire department can save a lot of money!
It means that if this modular firefighting platform comes out, it will cause a **** storm in the field of heavy-lift fire truck chassis!
