ANALYSIS AND OPTIMISATION OF THE NEEDLE TRANSFER MECHANISM
Original language description
The paper is concerned with analysis and optimisation of the needle transfer mechanism by means of the software Pro/Engineer Wildfire 4 with the aim to reduce the noise at high r. p.m. of the machine. There has been carried out an optimisation of selected parameters of the mechanism with the aim to avert the vibration of the element that controls the moment of release of the needle during its transfer from one needle bar to the other one. Subsequently, there is carried out a sensitivity analysis of theeffect of designing parameters of the mechanism upon the velocity of impact of the controlling element upon the machine frame. On the basis of results of the analysis and optimisation, there have been proposed modifications of the design of the needle transfer mechanism, and subsequently, they have been verified experimentally by measuring the sound pressure on a functional model.
