摘要

By the recent trend of high speed and efficiency, workingrncondition of a hydraulic excavator tends to be morernabominable, time varying and frequently with impactrnaccompanying and the structure of it is prone to be morernand more complex. Consequently, structural static andrndynamic synthetic performances are desired to be higher.rnFurthermore, structural static and dynamic optimizationrnincluded in entire performance optimization plays arnsignificant role in complex mechanical system generalizedrnoptimization. This paper puts forward a new method tornrealize the structural static and dynamic collaborativernoptimization of hydraulic excavator working equipment. Thernmathematical model of static and dynamical optimization isrndeveloped basing on finite element analysis and testingrnresults of static and dynamical characters of hydraulicrnexcavator working equipment. The paper introduces set-uprnof testing system and presents the experiment results thatrnare used to validate the static finite element models and torn* This research is supported by the National 863 Program of Chinarnunder Grand Number No. 2001AA412110 and the National SciencernFoundation of China under Grant Number No. 59635150.rnupdate the dynamic finite element models. The optimumrnresults prove the present method efficient and effective.
