Analysis of the mechanics of wheel balance block based on inertia tensor |

| Abstract: | The automobile wheel high--speed rotating mechanical model is established,and then based on the inertia tensor of the additional stress caused by dynamic unbalance.Through the calculation of an example,it is found that the additional stress caused by dynamic unbalance might be 40 times the weight of wheelIThen we discussed the importance of the wheel balance block improving driving comfort,safety,and also give some advice to eliminate or reduce the influence of dynamic unbalance advice. |
