Abstract: Aiming at the request of synchronization existing in the test system of dynamic characteristics of steering column lock, the problem of synchronization between motion control, data acquisition and results display was successfully solved by using the multithread technology. The hardware structure and the software design were introduced, and the multithread technology was described in detail. The results show that: the system can meet the need of realtime, reliability and efficiency of guidance. The precise parameter testing technology in course of the system is greatly improved and remarkable economy benefit is gained.
Key words: dynamic characteristics; steering column lock; montion control card; realtime multithread
