简介:对航空发动机用封严橡胶材料进行模拟工况下可磨耗性的研究。结果表明:可磨耗性模拟试验和实际工况下的磨损行为非常相似;封严橡胶材料在不同试验条件下有不同的磨损形貌和磨屑形态。研究中出现了3种典型的磨损形貌:在线速度(m·s^-1)/入侵速率(μm·s^-1)/入侵深度(μm)为100/5/1000的试验条件下,出现具有明显刮痕的磨损形态;在100/400/1000的试验条件下,出现沙丘状的磨损形态;在275/100/1000的试验条件下,呈现出鱼鳞状倒刺的粗糙磨损形态。3种典型的磨屑形态分别为:在100/100/500试验条件下为细小粉末状的典型磨屑;在100/275/1000试验条件下磨屑呈2—3mm长的搓泥状;在275/100/1000试验条件下出现了有一定长度的条状或不规则片状的磨屑。
简介:本文设计了一种基于双NIOSⅡ软核处理器的焊枪摆动器伺服系统,系统采用FPGA嵌入NIOSⅡ软核处理器进行控制,一个NIOSⅡ软核对焊缝跟踪的图像进行控制,另一个NIOSⅡ软核根据图像处理的信息实现对焊枪摆动器的控制。两个NIOSⅡ软核的结合实现了行走电机和焊枪摆动电机的运动,使两者有机结合实现设定的摆动焊接方式,并可以通过改变摆动参数实现对焊枪摆速、摆幅、左右滞时的任意调节。实验结果表明:基于双NIOSⅡ的焊枪摆动器伺服系统设计灵活、结构简单。
