    摘要:

    在建立永磁直線同步電動(dòng)機(jī)驅(qū)動(dòng)結(jié)構(gòu)機(jī)械模型的基礎(chǔ)上，采用有限元仿真分析運(yùn)動(dòng)部件在不同位置時(shí)法向力變化對(duì)龍門結(jié)構(gòu)橫梁變形的影響，得出橫梁在y軸方向的變形曲線。實(shí)驗(yàn)測(cè)得橫梁背面變形，并與仿真結(jié)果對(duì)比分析，得出電動(dòng)機(jī)定子磁場(chǎng)對(duì)應(yīng)的法向力。實(shí)驗(yàn)結(jié)果驗(yàn)證了仿真結(jié)果的正確性。

    Abstract:

    On the basis of permanent magnet linear synchronous motor (PMLSM) feeding system mechanical model, effects of normal force of moving parts in different stroke to deformation of a gantry type beam were analyzed by finite element method. A curve corresponding to y irectional deformation of the beam was achieved and the deformation of the beam was measured. The normal force of PMLSM was achieved by finite element simulation and relevant experiments. Deformation of the tool point was analyzed by finite element method and compared with the experimental results. The simulation results were verified to be reliable. 
