nilynch 发表于 2019-06-27 13:51 举个例子，一个车重1吨，另一个车重10吨，车身的刚性肯定是不同的，显然10吨那个绝对刚性要好很多，但是这能说明10吨那个车各种性能好吗，我觉得未必，因为它自重大，刚性大是必然的需求。 所以，俺觉得，刚性大不是厂家给用户的福利，只是厂家这个结构设计下的必然结果，拿来说事毫无意义。当然，在合理的框架下，不同厂商对刚性设计余量会有不同的看法，这个余量，才是给用户的福利，可惜这个余量不是单独测试车架就能得到的。 本帖由 无忌论坛V3.1.0 iPhone6plus iOS12.3.1 客户端发布 |

扭转刚性这个概念对公众来说过于疏远，车厂很少拿这个当宣传点，我记得当初也就只有奥迪A1短暂的炒作过一段时间，结果也是无疾而终。相应的数据关注度不高，也很少有公布。

触目皆是 发表于 2019-06-26 19:34 我觉得这个刚性要跟车的自重以及结构联系在一起看，这车再怎么拧巴的最大承受力就是其自身以及载荷，达到一定程度再增加刚性毫无意义 或者，是否可以这样理解，a车结构设计合理，无需过高刚性就能保证正常使用，b车设计不合理，必须极大的提高刚性才能正常使用，毕竟厂家不是※※，能用10000刚性的结构为啥要上30000 本帖由 无忌论坛V3.1.0 iPhone6plus iOS12.3.1 客户端编辑于：2019-06-27 08:06:14 |

葱烧海参 发表于 2016-5-3 01:32 简单用抗扭刚性强弱来评价一部车的品质我是不认同的。比如丰田的大皮卡就比同类型的福特和雪佛兰皮卡抗扭刚性要差！但是二手价格却是最高的！说明抗扭刚性高和结实耐用没啥直接关联。特别是对于一部用来干粗活儿的车尚且如此，用来拉人的车相比更影响轻微了。 |

什么是车身抗扭刚性
分享| 2015-04-08 20:55 bzk***@163.com | 浏览 212 次 汽车 2015-04-08 21:00 提问者采纳 热心网友 打个比方，你把整部车当做你的一只鞋，如果你用双手去扭转这只鞋，要是轻易就能扭很大角度，鞋的抗扭刚性就低，反之则高。车也一样，前后轴在行驶过程中会出现不在一个平面上的情况，这时除了车的悬挂系统会变形外，车身多少也会产生变形，如果车身很容易产生扭曲变形，抗扭刚性就低，反之抗扭刚性就高。 轻型越野汽车非承载式车身抗扭特性的研究 伴随汽车的普及，轻型越野车以其高越的通过性和操纵稳定性而逐渐受到人们的关注。越野汽车在路况较差的路面上行驶时产生的振动和冲击会通过车架传递给车身，当悬架变形时，车身不可避免的会产生一定的扭曲，所以对于越野汽车车身的运动和结构分析是必不可少的环节。在设计人员进行车身设计时，车身结构在疲劳寿命、装配以及使用要求方面分别需要足够的强度和刚度来保证，因此，刚度和强度的校核是车身结构设计的主要工作之一。由于汽车车身结构复杂的空间结构以及受力情况，运用以往的经验法或者类比法来构思车身结构时，比较容易造成过剩或者不足的强度... |
