摘要
为了实现机液耦合条件下轴向柱塞泵的精确建模和优化设计,提出了轴向柱塞泵多学科融合建模与集成优化方法。以国产I3V2-10S型轴向柱塞泵为对象,分别建立了ADAMS机械系统模型和AMESIM液压系统模型,通过ADAMS和AMESIM之间的接口模块设计实现了柱塞泵机液耦合建模和联合仿真,并利用iSIGHT软件集成了该机液耦合模型,以该柱塞泵出口体积流量脉动率最小为目标,对配流副中吸排油节流口最大开口等效直径、吸排油闭死角、柱塞包角、吸排油预开口量等参数进行了优化设计。结果表明:在负载工况分别为10、14、18、22、26、30MPa时,优化后的泵出口流量脉动率比优化前分别降低了14.59%、18.57%、21.50%、23.44%、24.03%、25.49%,最后通过实验验证了仿真和集成优化数据的正确性。
In order to realize the precise modeling and optimization design of axial piston pump under the condition of mechanical hydraulic coupling,a method for multidisciplinary coupling modeling and integrated optimization for axial piston pump was put forward.Taking domestic I3 V2-10 Stype axial piston pump as the study object,the mechanical model and the hydraulic model were respectively built in ADAMS and AMESIM.The interface communication between ADAMS and AMESIM was successfully implemented and the simulation of the mechanical and hydraulic coupling models was completed.Besides,in order to achieve the minimum outlet ripple ratio of this pump,the coupling model was integrated by iSIGHT software.The structures in valve plate pair such as oil suction and discharge orifice maximum equivalent diameters,oil suction and discharge dead angles,piston wrap angle,oil suction and discharge pre-opening degree,were optimized in iSIGHT.The results showed that the outlet flow ripple ratio of this pump was reduced by 14.59%,18.57%,21.50%,23.44%,24.03% and 25.49%,respectively,after optimization when the load was 10,14,18,22,26,30 MPa,respectively.Finally,the correctness of simulation and integration optimization data was verified by experiments.
