Domestic lawn tufting machines is an inevitable trend, and the research on the dynamic characteristics and vibration of the shaft system of lawn tufting machines is the key technology to achieve high productivity and high speed.
Taking the spindle eccentric wheel mechanism of the lawn tufting machine as the research object, a three-dimensional solid model is established with the help of mechanical design software, and the corresponding three-dimensional finite element model is formed with the finite element analysis software, and the modal analysis of the spindle eccentric wheel mechanism is carried out. The response analysis was carried out, and the natural frequencies, mode shapes and displacement time history curves of the excitation points of the first five orders were calculated.
The analysis results show the strong and weak distribution of structural vibration of each part of the main shaft eccentric wheel mechanism and the weak area of anti-vibration, which lays a good foundation for the high-speed research and optimization and improvement design of the lawn tufting machine and provides a more valuable theory. in accordance with.
