From the theoretical study presented in [1], we investigate the experimental feasibility of the active seat suspension to improve ride comfort. The prototype of the reversible electromechanical actuator used in the active seat suspension is presented. First, the kinematic guide with a vertical auto-levelling system is described. Second, the electromechamical actuator and the power drive transmission are presented. It is noticed that the prototype design is achieved with a systemic approach taking into account the industrial constraints. Then, the laboratory experimental setup is described. Several tests are performed on the prototype for model validation and performance purposes. Correct force feedback control in the actuator is verified. The real performances of the active seat suspension on a prototype is investigated for different pertubation inputs. Experimental results clearly show the efficiency of the active seat suspension to improve passenger comfort and demonstrate its feasability. 相似文献

For the complex structure and vibration characteristics of the seat and cab system of truck, there is no reliable theoretical model for the suspensions design at present, which seriously restricts the improvement of ride comfort. In this paper, a 4 degree-of-freedom seat-cab coupled system model was presented; using the mechanism modeling method, its vibration equations were built; then, by the tested cab suspensions excitations and seat acceleration response, its parameters identification mathematical model was established. Combining the tested signals and a simulation model with the parameters identification mathematical model, a new method of hybrid modeling of seat-cab coupled system was presented. With a practical example of seat and cab system, the parameters values were identified and validated by simulation and test. The results show that the model and method proposed are correct and reliable, and lay a good foundation for the optimal design of seat suspension and cab suspensions to improve ride comfort. 相似文献
