应力测试是汽车行业常用的疲劳寿命分析手法,当车身零件发生焊点开裂等疲劳破坏问题时,在应力集中位置贴伏应变片,然后在特定的恶路进行应力测试,采集应力数据,结合材料的疲劳限度及S-N曲线,通过分析应力数据能判断出是否存在疲劳破坏... 应力测试是汽车行业常用的疲劳寿命分析手法,当车身零件发生焊点开裂等疲劳破坏问题时,在应力集中位置贴伏应变片,然后在特定的恶路进行应力测试,采集应力数据,结合材料的疲劳限度及S-N曲线,通过分析应力数据能判断出是否存在疲劳破坏的风险,从而协助分析车身零件疲劳开裂的原因,并结合CAE分析提出相应对策。此外,实施对策后,以相同工况再次进行应力测试,通过分析疲劳开裂对策后状态测量所得的应力数据,可快速判断其对策的有效性,从而提高对策成功率,确保新车型按时投产。 展开更多

According to Angelica Duran and Yuhan Huang, Mo Yan's "artistic works" are "towering within the literatures of the world." His novel Si shi yi pao (Pow!, 2o12) offers one of the clearest recent examples of what Shelley W. Chan calls Mo's "postmodern playfulness." In his afterword to Pow! Mo says that the story "gives way to an improvisation that swings between reality and illusion," thus suggesting the notion of "hallucinatory realism" as a "blending" or "merging" of the illusory and the real. This article examines the ideology--that is, the class politics of consciousness--of this swingy postmodern storytelling, taking a critical view of Mo's playfully bold assertion: "I've always taken pride in my lack of ideology, especially when I'm writing." I argue that the swinginess of "imagination" in Pow! embodies what Marx calls a "happy confusion" that (re)articulates the "post"-class doctrine of "combine two into one." 展开更多
