Abstract
This paper presents the prototype shock reduction system (SRS) for the human supporting recoil mechanism device (HSRMD) subjected to impact force. Based on the parametric study of the HSRMD module, in order to reduce the force transmitted to the mounting body from the HSRMD, the passive and semi-active type shock reduction systems are studied. Parameters of the passive type SRS are determined by an optimization process under constrained conditions on the basis of the simplified HSRMD-SRS-human interaction model. The semi-active type SRS is devised using a MR damper with a feasible control scheme considering the disturbance characteristics. The performance of both systems is evaluated in a series of experiments using precisely constructed test setup. Finally, the transmitted force and linear impulse are estimated in the HSRMD-operator interaction condition for further developing process.
