Chapter 374 Box-Type Long Range Rocket Launcher
Chang Haonan cleared his throat:
“About next month, the software will officially release the first trial version. At that time, you only need to submit it through official channels. By applying for a trial, you will be eligible to use the beta version. "
"In the public testing phase, the software is completely free, but after the official version is released, annual licenses will be charged based on different user levels and versions. Cost.”
This approach has been proven effective by countless Internet companies in the future.
Use low prices or free services to cultivate user habits first, and then start charging after capturing enough market share.
Although Chang Haonan does not develop software to make quick money by cutting leeks, the principle is similar after all.
"Then this official channel..."
The routines people in this era have seen are relatively simple, and Rui Xiaoting was naturally attracted to them.
He even directly ignored the part about "authorization fees" at the end.
Besides, he didn’t pay for it himself anyway.
“When you go back, I can give you an activation code. When the trial version comes out, I will send you a box of CDs by mail. Just enter the activation code and you can use it.”
“As for the subsequent authorization, as long as each organization pays a fee, then everyone in the entire organization can use it, just like the currently commonly used AutoCAD.”
Commercial software The main users faced are not individuals. The authorization threshold does not lie in the act of obtaining the software itself, but in the commercial activities carried out by users using the software. Therefore, there is basically no need to consider the issue of piracy.
In other words, for example, if Jinling University of Science and Technology buys a license from Chang Haonan, then its research and commercial activities can legally use this software.
As for the specifics of whether the software installed in each person's computer is genuine or pirated.
Not important.
And having said that, it is only 1997. It will take another two years for Judong to allow pirated versions of Windows and Office to spread around the world in order to occupy the market. The domestic software copyright situation is actually much better than it was at the beginning of the 21st century.
“In addition, I know that there are many universities and research institutes in Jinling. If you can recommend our software to other brother units, you can also get corresponding discounts when getting licenses in the future.”
In fact, since Chang Haonan is currently leading a project team, which is still a scientific research institution, no specific sales principles have been determined yet.
However, this did not stop him from continuing to refer to the promotion model of Internet products in his impression.
Rui Xiaoting looked at Chang Haonan with a sincere face next to him, and felt that something was not right.
But after thinking about it, I always felt that I would not suffer any loss:
"Okay, then I will try it first."
Soon, under the guidance of Chang Haonan Next, a new model is imported into the computer.
"It seems completely different from the Guardian 1..."
Chang Haonan said, looking at the six rectangular directional tubes on an 8*8 chassis launch vehicle in front of him.
Even a pure layman can see the huge difference between the two.
"And why do you look more like a missile..."
"After all, technology has improved."
Rui Xiaoting made the final fine-tuning of the model as he spoke:
“The previous chassis was selected in 1992, and it was not very satisfactory in terms of load-bearing capacity, off-road performance or stability. Now Wanshan Special Vehicles is cooperating with the Minsk Automobile Factory and plans to start producing domestically produced transport-erector-launch vehicle chassis next year. We have temporarily built a model using the parameters of MAZ543 and will fine-tune it later.”
< br>Although the elastic support theory no longer requires the vehicle body to maintain absolute rigidity during the launch process, for the sake of firepower density and vehicle body life, the vibration amplitude and period cannot be too exaggerated.
“As for the directional tube... In fact, this can be regarded as a launch box. The two launch boxes are a set, and each vehicle is equipped with three sets. This way, after the shooting, you don’t have to worry about reloading, and you can prepare it in advance. Once the new launch box is put in, you can continue to fire the second round. According to our calculations, this can shorten the fire interval between the two rounds from about 30 minutes to less than 10 minutes. However, this function must be purchased at the same time. The designed reloading crane can only be realized."
Chang Haonan suddenly felt that he had met his opponent.
In terms of bundled sales, you still know a lot...
Then he continued to add:
“Of course, if the customer is really short of money, they can also choose to use the original The Tiema XC2200 chassis has the same directional tube as the Defender 1. "
The 8*8 TEL chassis is quite expensive.
For most equipment using this type of chassis, the cost of the vehicle will generally account for half or more of the price of the entire system.
And except for a few countries such as Damao or China, it is true that not all users have a particularly persistent pursuit of the off-road capability of long-range fire support.
While the two were chatting, Rui Xiaoting had also quickly completed the debugging and inspection of the model.
"Uh, what should I do next, copy the model, or draw it again?" When talking about redrawing, his eyes glanced at the graduate student behind him who came with him.
Bringing one more person here is not just for carrying bags.
The latter only felt a cold air spreading from the soles of his feet.
Drawing a diagram of this complexity on-site...
“No need, you can just add a statement to call the program file in front. We have reserved all common modeling on the market. The interface of software engineering files, including SolidWorks, can directly import data. ”
Chang Haonan still didn’t know that his image was close to the savior in someone’s heart.
“So convenient?”
Rui Xiaoting quickly entered a sentence as instructed.
As expected, a message indicating that the data call was successful appeared on the screen.
After a few seconds, a new dialog box popped up, which contained the modeling diagram of the new rocket launcher.
“…”
In this era when even hardware versatility is poor, almost no one has considered the versatility of different software——
There are actually no technical obstacles, but in order to seize the market exclusively, some software developers will deliberately make their file formats different from similar competing products.
It was hell for the engineering staff.
Even if the underlying parameterization logic is completely the same, calling the design drawing from one software to another requires a rather complicated transcoding process.
Even a very skilled person may take several hours to complete.
If your luck is even worse, you may even have to redraw it.
But now, he did it all in less than 5 minutes.
"The next step should be gridding..."
As the progress continued, Rui Xiaoting became more and more skilled in the operation.
"Uh...why are there so many options here?"
A command line interface popped up on the screen, with 5 options appearing.
The key is that he can't understand any of them.
“Oh, these are the 5 different meshing algorithms we have preset.”
Chang Haonan explained:
“Your model is a bit big. The generation may require memory usage. You can split the directional tube, bogie and chassis into three parts and generate them separately, and then choose the second option.”
“Is it okay to just split the three parts?” >
Rui Xiaoting's hands on the keyboard shook, leaving a few irregular characters on the screen.
You must know that when he did finite element analysis before, this step even required separately generating subdivided structures such as hydraulic outriggers, girders, and subframes.
"If you find it troublesome, maybe... you can just combine the bogie and the directional tube."
Chang Haonan said in an uncertain tone.
“No, that’s not what I meant...”
Rui Xiaoting's whole body was numb.
It is easy to go from frugality to luxury, but it is difficult to go from luxury to frugality.
Even if the software in front of you does not even have a serious graphical interface, the operation still needs to be carried out through the command line.
But when I think about how I have to continue to suffer the torture of ABAQUS after I go back this time, I feel that the world is dark.
So he made up his mind to get the principal to get the authorization for this thing at all costs after returning to school.
What money is not money.
Vulgar!
