For the synchronous shaft system of large ship lift,the coaxiality of drums is one of the key technical indexes to secure the safety and reliability of the system.This paper is aiming at the synchronous shaft system of ship lift and considering the characteristics of multi-drum and large-span structure of synchronous shaft system,then proposes a measurement method of coaxiality of synchronous shaft based on laser measurement in three-dimensional space domain.This paper also studies the effective post-processing algorithm of measurement data,and builds the evaluation model of coaxiality of ship lift synchronous shaft.Meanwhile,the coaxiality of synchronous shaft is evaluated based on the measured data.The evaluation result shows that the coaxiality of the drum is in good condition and can meet the requirements of operation.
