Abstract

In order to investigate sawing dynamics on band sawing machine, a general dynamic model is proposed to represent the actual system with the dynamics of strain of band saw, mechanism of hydraulic motor with proportional valve and load of sawing. Firstly, an element strain model of band saw along the arc coordinate is established with the elastic deformation theory of closed band saw, momentum theorem of band sawing element and sawing load. Then, the relationship between control input, sawing load and band saw tension is addressed with the dynamics of hydraulic motor with proportional valve. The results of dynamic simulations and experiments show the proposed model can effectively describe dynamics of band sawing process. This model provides a useful way to improve dynamics of band sawing.
