大概1.1 [kgm^2] (对19"直径, 255mm 宽的车轮)

请问lz仿真的时候用的什么轮胎模型，个人经验好像不同模型定义的轮胎的转动惯量是不一样的。
Adams/Tire Handling Module and the Pacejka Motorcycle Tire model, the inertia given for the wheel part must be equal to the total inertia of the tire and the rim.

In FTire, a part of the tire can move with respect to the rim. Therefore, the tire mass and moments of inertia have to be split into two parts: a part that is moving with the rim (wheel part) and a part that is moving with the tire itself.
不过对于UA，PAC89 PAC 来说都应该是个整体。但是SWIFT好像也要分开，因为它的轮辋和带束是分开。不过MD R3里面好像没有SWIFT了。
