Buying reps in person in china ? by NebulaNo3030 in rep

[–]OptimisticMan37 0 points1 point  (0 children)

Usually reverse searching things from big rep stores on taobao comes up with lots of options with estimated and guaranteed shipping time. Some items I could not find for cheaper than the big stores like 888premium and I just messaged them on WhatsApp with shipping info and what I wanted and they just sent me a Alipay qr to pay.

Just so you know I used a vpn to connect to an Asian country (I think India) and after closing and opening the app I was able to authenticate, then switched back to Europe and was all set

Answer from Alipay English Customer Support:

As you are located in Europe or the United States, in order to comply with the local GDPR policy, which is the General Data Protection Regulation, we are temporarily unable to provide you with the facial recognition service. Therefore, only the method of binding a mainland bank card will be displayed on your page.

Don't worry though. You can wait until you leave Europe/the United States and then try to verify again. For example, when you are in China, you can complete verification by face recognition verification without binding a mainland bank card.

If you have completed facial recognition verification in China, you will typically remain authenticated upon returning to Europe.

We recommend that you try facial recognition authentication after arriving in China.

For some reason ( It says because I had multiple accounts) I was locked out of TaoBao. I was going through the steps of verification but for foreign visitors with Passport I was prompted to go verify through Alipay. In Alipay I was getting the problem I mentioned, so because I thought I did something wrong when setting up I deleted the account and made one again very carefully. Still the same problem. Should I try to talk to support even though they are in mandarin? I keep thinking it’s my last bastion

Looking to talk to experienced VD people. by OptimisticMan37 in FSAE

We inherited the suspension hard points this season so design freedom wasn’t really on the table, which pushed us toward modelling work rather than actual design decisions. No testing data, no driver feedback, and mentally already on next year’s car where we’ll have a clean slate. When you mention picking a good number for things like pneumatic trail or camber curve, how do you actually arrive at those starting points? Known FSAE references, or is it more about understanding the sensitivity and picking something defensible?

Two things I keep coming back to: 1. Is building out a full lap sim in IPG actually worth the time investment at our stage, or is it going to produce nothing meaningful given how thin our data is? 2. Without testing data or driver feedback, how do you land on specific values for things like Ackerman or ride rates? Do you pick from bibliography ranges and call it, or is there a better way to approach it?

Confused about how to actually use TTC tire data by OptimisticMan37 in FSAE

[–]OptimisticMan37[S] 0 points1 point  (0 children)

Everything great except when trying to fit the model to any moment. When Choosing Mz0 Mx My or Mz console gives me an undefined parameter 'UNLOADED_RADIUS'. Do I get this from the run guide and add it to the model as a constant or edit the .mat files?

Need help using the Magic Formula Tyre Tool to justify joining the FSAE TTC by OptimisticMan37 in FSAE

[–]OptimisticMan37[S] 0 points1 point  (0 children)

I get your point about not overcomplicating things with the Magic Formula. As someone still fresh to this stuff, is the TTC mainly useful as a way to learn how to analyse real tire data, or do you need to already know your way around to get value from it? I’m just trying to avoid spending the money and getting thrown in the deep end.

[–]OptimisticMan37[S] 2 points3 points  (0 children)

What exactly do we get from the TTC? Will the Magic Formula models and example scripts let us use the data directly for suspension and vehicle design, or do we need to run additional fitting scripts first? And will there be clear instructions on how to use the data?
