为提高重型液力自动变速器的主调压系统油压动态特性,在对重型液力自动变速器主调压系统回路中的主调压阀与控制压力调节阀工作原理分析的基础上,建立其数学模型,并基于AMESim搭建主调压系统仿真模型,从主调压阀阀芯直径d m3、控制压力调节阀弹簧刚度K c和控制压力调节阀遮盖量ulc展开主调压系统的油压动态特性分析.采用粒子群优化算法和遗传算法,对影响主调压系统油压特性的阀体结构参数进行优化设计.优化结果表明,优化后的设计参数能有效提高重型液力自动变速器的油压特性,验证了所建立主调压系统模型的正确性和所运用优化算法的有效性.

基于机器视觉的方法是刀具监测的重要途径之一,具有无损、直观反映刀具状态的优点,但采集高质量的监测图像比较困难。在微细加工中,由于主轴转速快,刀具尺寸细小,刀具在图像中的角度与位置具有任意性,在线监测的难度较大。针对微细铣削加工中,光照分布不均匀的在位图像捕捉系统获取的位置与角度任意的刀具图像,研究了一种精确提取刀具图像中感兴趣区域(Region of Interest, ROI)的算法。利用Hou
