Research on the Optimization of the Vibration Reduction Seat Based onGenetic Algorithm

Adopting the parallel mechanism as the main body of the seat and the active joints with spring damping elements as the vibration actuator, we established the damping seat model with the parallel mechanism of six degrees of freedom 3-PRPS. To achieve good damping effect, the damping space and flexibility of the mechanism were improved by affecting the velocity matrix with branched speed built by vectors. Optimal parameter values were obtained by genetic algorithm. Finally, results were synthesized and verified to provide an important theoretical basis for the practical application of the mechanism.
