12、ww.ten- 抗扭刚度主要表达车身的结实程度。不结实的车，在一个轮子上了马路牙子的时候，都能看到车身的微微 变形，这个就是抗扭刚度造成的。抗扭刚度有静态和动态2种，除此之外还有静态抗弯刚度指标。这些指 标都是越高越好（成本和其它条件所限，不会太高）。举一个比较严重的例子：曾经有媒体试车试架某国产 车（不是我隐瞒，原消息里就没提到品牌），经过了激烈驾驶后，车身刚度不够造成车身变型，车门打不开， 记者被卡在车里出不来，后来动用了救援工具才得以脱身.当代的乘坐用汽车，对静态抗扭刚度一般要求达到4,000 9,000 Nm/deg范围内，高性能车要求更高 的数值，一般在内 15,000-30,000

13、 N m/deg点评： Rolls Royce的Phantom，用沉重的车身换来了 4万牛米/度的静态抗扭刚度，这是一个相当高的值， 也是一个不得不提高的值，因为它的车身很重，马力很强劲。德国大众研发的1001匹马力怪兽布加迪威龙”，为了能够跑到400km/h，竟然造出了 6万牛米/度 的 恐 怖 级 车 身！ （参 见url = . n-structural-design/url）大众途锐的车身有3万7千牛米/度的静态抗扭刚度，而且这个值是用承载式车身创造出来的。 BMW的7系虽然很大又长，但是其静态抗扭刚度也达到了 3万5千牛米/度，对于这样大的一个车身， 这个数值是很优秀的。宾利的大陆G

14、T convertible，动态抗扭刚度是30Hz，这对一款convertible来说是一个令人吃惊的数 据。（参见url = . nental-gtc-in-depth/url）马自达RX-8的静态抗扭刚度比RX-7增加了 100%，达到了 3万牛米/度，这也是唯一能在网上查到 的日本车的静态抗扭刚度数据了。还有一个相关的消息是Nissan 350乙一个试车的法国人问到了静态抗 扭刚度数据，但是没有得到回答。我觉得我特别能够理解这个法国人的想法，因为350Z早些年的款型， 车身实再是不够结实，最后只能在后行李箱里加装了一块门型的铝合金加强筋（新款解决了此问题，此 高级毛巾架再也不会出现了），

15、当时国内的一些试车记者不知此为何物，还特意吹捧，拿着相机大拍特拍 估计日产公司的工程师们要是看到了这些报道，不知道该作何感想？国人太不重视车身的重要作用了，类似的，还有典型的要气囊不要安全带”等无知思想，再此稍稍提起， 不多作批驳前些天看广本的新款上市，说车身的刚度提高了百分之多少（国内款提高了 17%，国外款提高了 20%）， 但绝口不提其测试值，在所有的中文和英文的网站上，除了马自达的RX系列跑车，从来没有查到过日系 车的车身刚度数据，强烈鄙视之.Alfa Romeo 15931,400 Nm/degAlfa Romeo Spider11,200 to 13,000 Nm/deg （dep
