| Summary: | For the problem of current dynamics model of multi-body flexible belt drive large error in calculation and the actual calculation error larger and so on,by using the absolute nodal coordinate method,the model of contact with the movement of the multi-body flexible belt drive between the drive wheel and transmission belt is built,the variation index of flexible multi-body flexible belt drive during the contact process is studied.The results show that the angular velocity of the drive wheel unchanged before and after the improvements,the improved driven belt wheel angular velocity variation range is smaller than before improvement,the normal force per unit length of improved drive wheel is smaller than before improvement,the per unit length of friction of drive wheel in the range of wrap angle is larger than in most stages of before improvement the model,the relative tangential velocity of the multi-body flexible belt drive model is smaller than before improvement. |
