Abstract
This paper deals with optimization of a device designed for long-term dynamic testing of car seats. This kind of tests is important for car seat innovation with respect to improving safety and comfort of passengers. This type of testing is based on linear periodic movement of a car seat cushion on which a weight representing a passenger is placed. Movement of seat is generated by a cam mechanism. Several cam profiles were proposed by a computational software, in order to achieve acceleration occurring during a real car driving. Based on this information concept of the whole device was proposed. Thereafter the static and dynamic FEM analysis were carried out. Finally an optimization of the cam mechanism and the whole device was accomplished in order to achieve the best compromise of conflicting requirements of large acceleration at low frequencies.
