The polish mechanisms for composite material box is produced for polishing box within demanding error range, it is made up of gear system, shaft systems and other transmission parts, the clearance and eccentric in the assembly lead to motion error in the polish mechanism; hence, the error reliability of polish mechanisms should be investigated. The error distributions follow normal distribution, the parameter are defined according to the multi-object software ADAMS simulation experiments results. The position accuracy reliability analysis bases on the Monte-carol method to estimate reliability of the polish equipment. Error distribution parameters are calculated with ADAMS simulation experiments instead of the real experiment, which can spare the experimental cost and time and makes it easy to predict reliability with little consumption. The error analysis focuses on the gear system and shaft system mainly, the other factor from other parts are neglected due to their little influence on the error, the reduced analysis benefits to the rapid obtaining reliability results. |
