The Application of Neural Networks to Modular Arrangements of Predetermined Time Standards

To study the method of reducing low-frequency vibration noise tires, a passenger car tire (205/55R16) is taken as research object. The dynamic grounding characteristics and reduction mechanism cat’s paw pad are analysed. showed that swing deformation pads during walking process cats one main ways to reduce impact from ground achieve silencing. analyse influence on noise, divided into five areas, ten areas analysed through tests. Pearson correlation analysis used obtain eight most relevant parameters with multiple linear regression conducted between areas. product coefficient average value contact area shows central tread contributes noise. bionic cat realized by setting staggered side branch pipe groove in centre tire, using finite element method. results when rolls, amplitude fluctuation range radial excitation force acting reduced compared original improved.
