Abstract EN
The finite element model of the seat rail is established with a spring-damping element to simulate the ball in the rail joint part.
The stiffness and damping parameters of the joint part are determined by the combination of finite element method and experiment.
Firstly, the natural frequencies and modes of the guide rail are obtained by modal experiment.
The stiffness of the spring-damping element is optimized in the finite element software to make the natural frequencies and modes of the system consistent with the experimental ones.
Secondly, the dynamic response curve of the key nodes is obtained through sweeping experiment, and the damping of the spring-damping element is optimized in the finite element software to make the nodal response of the system output consistent with the experiment.
Then, the gap of the joint part of the car seat rail is studied considering the factors of load and structure randomness.
The influence factors of the gap are selected by Hammersley experimental design method.
The results show that the gap is normally distributed, and therefore the confidence interval of the gap is obtained.
Finally, the joint probability distribution of the gap is obtained under the condition that the load and the structure are all random, which provides the theoretical guidance for determining the reasonable gap of the joint.
