Abstract
The article analyzes the design of the vibration mechanism with a counterweight of the gripping-cutting device, which ensures the balancing of the resulting forces and moments of forces. The design development of the vibration mechanism of the gripping-cutting device was performed by adding one counterweight, which will provide the required unloading of the supports from the unbalanced masses of the vibration mechanism. To analyze the design of the vibration mechanism with a counterweight, the mass of the counterweight was determined by calculating the translational moving and rotating parts of the mechanism. Dynamic studies were carried out in the SolidWorks Motion program on the developed 3D model of the vibration mechanism design with a counterweight. As a result of the analysis of the design of the vibration mechanism equipped with a counterweight, the moment on the mover was simulated and the values compared with the simulation results obtained on the vibration mechanism without a counterweight for a tree weighing 50 kg and at a rotation speed of the mover of 150 rpm. Comparison of the results of modeling the torque on the vibration mechanism drive under equal conditions showed that the maximum torque on the shaft without a counterweight is 435804 N mm, and the maximum torque on the shaft with a counterweight is 331931 N mm. The difference in the values of the maximum torques on the vibration mechanism drive shaft showed that the use of a counterweight reduces the maximum torque by 23.8%.
