Abstract
According to the characteristics of car seat structure and the distribution of car seat load, the finite element static strength model of the car seat is constructed in this paper. The model contains shell elements and beam elements. Some seat structure elements such as welding connection, screw connection, pin connection are simplified in the model. Simulation analysis of the static characteristics of car seat backrest frame model is carried out. At the same time, the experimental research on the static strength characteristics of the back seat is made by the measurements of non-electric physical quantities. By comparing and analyzing the results of experiment and computer simulation of seat static strength, the practicability and credibility of the seat static finite element analysis model and simplified model constructed in this paper are verified. It also proves that the simulation of various connecting forms of the seat structure is effective and is a reliable method in the structural design of the car seat. The model and simulation of the car seat can reduce the cost and shorten the design period.
