摘要：
This paper deals with procedures for dynamic modeling of structure and mechanisms for bucket wheel excavators (BWE). Identification of external load caused by resistance to excavation presented in the paper enables including of all relevant structural parameters, as well as parameters of duty cycle and soil characteristics. By applying before mentioned procedures corresponding dynamic models are set up for BWE TAKRAF SRs 1200 and KRUPP SchRS 1760. Based on dynamic models we have solved some specific problems for BWE: defining loads in stays of bucket wheel boom, response of mechanism for bucket wheel boom lifting, estimation of rheolinearity level, analysis of impact of counterbalance weight on the dynamic parameters and system response.
