Abstract: . The six-bar linkage mechanical press is a crucial equipment in the preparation of metal bipolar plates for fuel cells. The dynamic characteristics of the transmission system have a significant impact on the precision of the slide operation, which directly affects the quality of the bipolar plate forming. In this article, A dynamic model of the six-bar linkage transmission system under complex forming workloads was established to research dynamic characteristics. The dynamic characteristics of each bar was analyzed under load conditions. Combining with the orthogonal experimental method, we investigate the various parameters influence on the press slide precision. Through an six-factor orthogonal experiment, the results show that the down-push rod dynamic characteristics are the most important factor affecting the slide stroke precision under the transmission system's workload conditions. Therefore, it is necessary to optimize the down-push rod design and manufacturing process. The results of this study have a certain reference value for the design and optimization of the six-bar linkage mechanical press, and the improvement of the quality of metal bipolar plate preparation for fuel cells.
