【摘要】：介紹三相異步電機(jī)-軸向柱塞式電液泵(EHP)的集成結(jié)構(gòu)與工作原理,計(jì)算電液泵機(jī)械損耗,在Ansoft軟件中建立電液泵電機(jī)模型,仿真分析電液泵的電磁損耗,并在此基礎(chǔ)上建立有限元耦合模型,借助Fluent軟件仿真分析液壓油在殼體內(nèi)腔的流動(dòng)與溫度分布狀態(tài),以及關(guān)鍵零部件的溫度分布。有限元分析結(jié)果表明,液壓油可以在流道內(nèi)充分流動(dòng),并且額定工作狀態(tài)下,當(dāng)進(jìn)口液壓油溫度為35℃時(shí),電機(jī)定子最高溫度不超過58℃,轉(zhuǎn)子最高溫度不超過40℃,散熱效果好于傳統(tǒng)電動(dòng)機(jī)-泵組。針對(duì)定子內(nèi)部溫度較高的現(xiàn)象,研究了定子四周打4個(gè)直徑10 mm的通孔后的溫度分布情況,并與打孔前進(jìn)行了對(duì)比,結(jié)果表明,打孔后電機(jī)定子最高溫度降低了0.6℃,局部區(qū)域溫度降低超過3℃,散熱效果改善明顯。
[Abstract]:This paper introduces the integrated structure and working principle of three-phase asynchronous motor and axial plunger type electro-hydraulic pump (EHP), calculates the mechanical loss of electro-hydraulic pump, and establishes the electrohydraulic pump motor model in Ansoft software. The electromagnetic loss of the electro-hydraulic pump is simulated and the finite element coupling model is established on the basis of which the flow and temperature distribution of the hydraulic oil in the shell cavity are simulated by Fluent software. The finite element analysis results show that the hydraulic oil can flow fully in the flow channel, and when the imported hydraulic oil temperature is 35 鈩，
