Characteristic Parameters of Cushion in High-Speed Train (CRH) Contribute to Seat Pressure Distribution Analysis

Article Preview

Abstract:

Based on the seat cushions in high-speed train, three main characteristic parameters, surface angle, width and height are involved in this simulation experiment analysis. With this CAE method, a standard buttocks model fit to seat cushion is imported, and the study on seat pressure distribution is taken through characteristic parameters of seat cushions related to different concave surfaces using ANSYS’s finite element analysis, and contribute to much flexible and more adjustable feature points, use seat pressure distribution to determine geometric parameter according to maximum pressure points, the result in this work finally satisfy the standard of optimization, and helps to assist reliability design of seats in high speed train.
