为了降低电力推进用永磁同步电机水下噪声,提出一种新型锯齿载波减振控制方法。该方法应用锯齿载波替代传统三角载波进行空间矢量脉宽调制,使相电流基波两侧的边带谐波幅值大幅降低,从而抑制电机低频振动。针对锯齿载波带来的相电流高频谐波增大的问题,进一步应用基于随机开关频率和随机零矢量的双随机控制,使得开关频率整数倍处的相电流高频谐波幅值有效降低,从而降低电机高频振动。实验结果表明,锯齿载波双随机控制对低频和高频振动均有明显抑制作用,尤其是锯齿载波较传统三角载波低频振动加速度降幅可达60%。

阐述了采用重力铸造方式生产的GW4D20铝合金发动机缸盖,在气密性检测中发现的渗漏问题。采用金相显微观察及宏观分析等手段,研究了渗漏部位的组织与缺陷。结果表明,缩松及缩孔是导致缸盖渗漏的主要原因。浇注过程中砂芯挥发出来的气体及铝液氧化皮夹杂物增大了缸盖铸件在凝固过程中的缩松和缩孔倾向。针对上述铸造缺陷,加强了铸件缺陷部位的补缩,减少气体来源,保证模具型腔排气畅通,有效地控制了缸盖铸件在铸造凝固过程中缩松、缩孔及氧化皮的产生,降低了气缸盖的渗漏。

目的研究噻托溴铵与布地奈联合对轻中度支气管哮喘患者临床治疗效果。方法选取2016年1月至2017年11月在本院接受诊断和治疗的80例轻中度支气管哮喘患者为观察对象,并将患者分为参照组和实验组,每组40例。参照组单独采用布地奈德治疗,而实验组在布地奈德的基础上联用噻托溴铵,比较两组患者的治疗总有效率、治疗前后的哮喘评分以及治疗前后患者肺功能的变化情况。结果治疗前,实验组与参照组的哮喘评分和肺功能指标水平比较差异无统计学意义。治疗后,两组的肺功能均得以改善,但参照组患者的改善程度低于实验组(P<0.05)。治疗后两组的哮喘测试控制评分均有所提高,但参照组的提高程度低于实验组(P<0.05)。参照组的治疗总有效率低于实验组(80.00%vs 95.00%),差异有统计学意义(P<0.05)。结论在轻中度支气管哮喘患者的临床治疗中,噻托溴铵与布地奈德联合用药的治疗作用比单独应用布地奈德更加明显,联合用药不但可有效改善患者的症状,还有利于改善患者的肺功能,临床疗效较为显著,故建议临床推广应用。
