Based on the rigid finite element method and multibody dynamics, a discrete model of a flexible conveyor belt considering the material viscoelasticity is established. RFE (rigid finite element) and SDE (spring damping element) are used to describe the rigidity and flexibility of a conveyor belt. The dynamic differential equations of the RFE are derived by using …Web

ادامه مطلبThe first equation is a static system or an instant of time when the machine is being operated. Usually this would be as the machine starts at maximum force before centrifugal force begins to take effect. The second equation is when the machine is dynamically being operated and accounts for centrifugal force also. That's my opinion.Web
