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= Io(zx)+mdzdx 惯性积...

The latter involves introduction of the moment of inertia tensor studied here; and, of course, the first law involves the location of the center of mass of the body. We begin, therefore, with the concept of the center of mass of a complex structured body and illustrate its application to ...

The Moment Of Inertia Tensor Mass is a measure of translational inertia. The greater the mass of an object is the more it refuses to get accelerated for a given force. Similarly, the moment of inertia is a measure of rotational inertia. It depends on both the mass and the distribution of...
[edit]Moment of inertia tensor For the same object, different axes of rotation will have differentmoments of inertia about those axes. In general, the moments of inertiaare not equal unless the object is symmetric about all axes. Themoment of inertiatensoris a convenient way to summarize all ...
More generally, the area moment of inertia tensoris given by by analogy with themoment of inertiatensor, which hasnegativesigns on the off-diagonal elements and, unlike themoment of inertiatensor, is not expressed in term of mass of thelamina. ...
The moment of inertia tensor is always a symmetric 3x3 matrix. I therefore suggest replacing all occurrences of "tensor J" with "symmTensor J" in: https://develop.openfoam.com/Development/OpenFOAM-plus/tree/develop/src/meshTools/momentOfInertia...
