Through the actual incident investigations, front collision patterns from the collision can contact form, collision speed from two aspects, divided into positive condition declivitous contact form, left, right, left bias tilt tilt right bias, left, right, right inclined offset tilt left bias in 23; etc. Collision speed mainly divided into 10m/h, 15m/h, 22m/h, 25m/h, 30 / h, 35m/h, 40 MB/h seven levels. Currently the collision can realize makers ounted for only the actual incident form of 2%. C6t automotive design
Frontal crash of several typical parameters, such as energy, displacement, velocity and eleration of the relationship between time and etc, and the relationship between them, constitute a frontal impact dynamics model of various. In order to analyze need, still need to add energy density, energy equivalent stiffness, strength, speed, etc. In the stage of conceptual design and project definition, use these parameters for different equivalence collision speed and the collision model with the same intensity) to establish the collision and strength of the damage index corresponding relation, the design parameters of the body structure of control.累死我了````
昨天有分享到"2021年Vultr新用户福利注册账户赠送50美元"文章,居然还有网友曾经没有注册过他家的账户,薅过他们家的羊毛。通过一阵折腾居然能注册到账户,但是对于如何开通云服务器稍微有点不对劲,对于新人来说确实有点疑惑。因为Vultr采用的是预付费充值方式,会在每月的一号扣费,当然我们账户需要存留余额或者我们采用自动扣费支付模式。把笔记中以前的文章推送给网友查看,他居然告诉我界面不同,看的不对...

今天早上相比很多网友和一样收到来自Linode的庆祝18周年的邮件信息。和往年一样,他们会回顾在过去一年中的成绩,以及在未来准备改进的地方。虽然目前Linode商家没有提供以前JP1优化线路的机房,但是人家一直跟随自己的脚步在走,确实在云服务器市场上有自己的立足之地。我们看看过去一年中Linode的成就:第一、承诺投入 100,000 美元来帮助具有社会意识的非营利组织,促进有价值的革新。第二、发...
