Henninger and A. Zopey and T. Ihde and C. Mehring}, country = {}, institution = {}, abstract = {The dynamic performance of a 4-way solenoid operated hydraulic spool valve has been analyzed by means of a one-dimensional modeling approach capturing flow, magnetic and fluid forces, valve inertia forces, fluid compressibility, and damping. Increased model accuracy was achieved by analyzing the detailed three-dimensional electromagnetic behavior of the solenoids and flow behavior through the spool valve body for a set of relevant operating conditions, thereby allowing the accurate mapping of flow and magnetic forces on the moving valve body, in lieu of representing the respective forces by lower-order models or by means of simplistic textbook correlations. The resulting high-fidelity one-dimensional model provided the basis for specific and timely design modification eliminating experimentally observed valve oscillations.}, journal = {International Journal of Mechanical and Mechatronics Engineering}, volume = {11}, number = {8}, year = {2017}, pages = {1483 - 1489}, ee = {https://publications.waset.org/pdf/10007816}, url = {https://publications.waset.org/vol/128}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 128, 2017}, }
