[Abstract]:Metal rubber damper has a strong bearing capacity, high damping, good impact resistance, high temperature resistance, low temperature resistance, good corrosion resistant performance. Suitable for military power and other harsh working environment. The metal rubber block is the elastic component of metal rubber damper, is a key component of metal rubber damper has a good damping performance. Therefore, research on analysis and evaluation of the performance of metal rubber block is of great significance in improving the performance and life of metal rubber damper.
The choice principle of the wire material of metal rubber net block the knitting process of metal wire mesh, metal rubber block cold stamping forming process and improvement were studied. The physical properties of the metal rubber block is studied by experiment and simulation include: relative density, tangent modulus and energy consumption factor and analysis. Influence factors of static characteristics and dynamic characteristics of metal rubber block and their.
According to the characteristics of the metal rubber block, a spring theory based on metal rubber block were modeled and micro processing, the constitutive equation of metal rubber block in micro units, theoretical analysis on stress state of the metal rubber block, and calculated the surface force and non the micro force unit stress constitutive equations of nonlinear equation theory; rubber metal was analyzed by Fourier series expansion, the linear dynamic equation of metal rubber; application of Masing model and its inference principle simplifies the derivation of the nonlinear bilinear model of metal rubber block deformation model and nonlinear restoring force is established. The metal rubber block; network parameters were predicted by using the artificial neural network, and the possibility of this method is verified by the experiment.
