In the chassis parts, many parts are also applied to the stamping process, such as some guard plates, swing arms, sub-frames, etc. Many problems in the stamping parts in the later period are caused by the unreasonable design in the early stage, so as a qualified product design engineer, you must also understand various processes. Below we will discuss some common problems in the forming of stamping parts. Common problems in general part forming mainly include: 1. Wrinkling; 2. Cracking; 3. Springback; 4. Surface quality (collapse, slip, impact);
In financial research, commonly used models include the following theoretical models:
It is generally used to explain important theories, especially theories at the micro level. The parameters in the model generally cannot be directly estimated, or the theoretical results do not require the fitting of real data, such as the MM theorem. Validating a model requires some variation or following the model's inferences.
Structured theoretical model:
The model is derived theoretically, but it can be verified or directly calculated by actual data or parameters. For example, BS option pricing.

St. Louis Fed President Bullard said yesterday that due to the banking crisis, financial pressures have increased in recent weeks, but they can be controlled through regulatory policies rather than interest rates. This remark seems to imply that the Federal Reserve will continue to raise interest rates, and will not change this position because of the risk events that broke out in the bank before. However, judging from the probability of raising interest rates implied by the federal funds rate futures, the probability of keeping interest rates unchanged at the current May rate meeting is close to 60%. Therefore, the price of precious metals continued to fluctuate and rebound yesterday. Moreover, precious metals still have bargain-hunting value in the current market where there are great differences in the path of future interest rate hikes, and at the same time, there are many uncertainties in the future economic outlook.
Why do lithium battery companies frequently deploy energy storage?

On the evening of March 27, Ningde Times issued an announcement stating that the company recently reached a supply agreement for a 450MWh battery energy storage project with HGP, a battery energy storage project development company. The two parties will also establish a long-term partnership to promote the implementation of up to 5GWh utility-scale and distributed energy storage projects to meet the growing demand for renewable energy in Texas, USA.
