Abstrakti

A new electro-mechanical servo pump (EMSP) is proposed for high-power variable pump fixed motor electro-hydrostatic actuator for heavy-duty vehicle application. The EMSP has a highly integrated structure with the displacement regulating unit inside the same shell. This results in more challenges for sizing during design stage. Therefore, a dedicated multidisciplinary model for the EMSP preliminary design is presented in this paper. Initially model parameters are analysed and classified into different categories. As a result, only a fraction of parameters such as pump displacement, motor nominal torque, etc. was employed for active EMSP sizing to achieve more effective trade off and optimization. Rest of parameters were generated automatically with various methods such as scaling laws, product database, and empirical equations. Next, the hydraulic, electrical and thermal dynamic characteristics were investigated in the model. Finally, a multidisciplinary model equipped with the parameter generation tools was proposed as a practical tool for the EMSP preliminary design. At last, dynamic simulation results of hydraulic, electrical and thermal under typical cycles were utilised to verify the model functionality. The performance of the given EMSP design option can be evaluated by the proposed model, which makes the preliminary design and optimization feasible.
