二Ixx 与整车侧倾 有了上面对俯仰的分析,其实Ixx 与侧倾是相同的道理,弯道中车辆离心力作用点也过质心。同样,车辆侧倾并不是绕其自身的质心,而是绕侧倾中心。同理,绕侧倾中心的侧倾角反应到质心处的转角已经非常小了,微分后的角速度也很小了。所以对于侧倾来说,Ixx对侧倾角的影响远没有侧倾中心高度重要。
Ellipsoid of Inertia(惯性椭圆体) 转动惯量计算 刚体角动量、惯性张量 惯性张量的变换 分析刚体的旋转运动,需要先理解的一个物理量:转动惯量。相比线性运动,旋转运动相对难理解一点。我们通过对比线性运动来理解旋转运动。 线性运动旋转运动 质量(m) 转动惯量(I) 速度(v) 角速度(ω) 加速度(a) 角加速度(a) 力...
平行轴定理:J=J0+md2 转动惯量张量(inertia tensor): J = 主对角线上为三个坐标轴的转动惯量,剩下的项称为惯性积(product of inertia): Jxy= Jyx= ∫(xy)dm Jyz= Jzy= ∫(yz)dm Jzx= Jxz= ∫(zx)dm 惯性积也有类似平行轴定理的坐标轴转换公式: Jxy= Io(xy)+mdxdy Jyz= Io(yz)+mdydz Jzx= ...
The mass moment of inertia and area moment of inertia both are represented byI. Sometimes it may be confusing, but you have to figure it out by the application. The mass moment of inertia is used as a rotational analog of mass, and the area moment of inertia is used mainly for beam e...
Fundamentals of Moment of Inertia The moment of inertia can be derived as getting the moment of inertia of the parts and applying the transfer formula: I = I0 + Ad2. We have a comprehensive article explaining the approach to solving the moment of inertia. Fundamentally, the moment of ...
