摘要
以某钢铁公司一台双小车料箱桥式起重机金属结构的应力检测为实例,采用静态应变仪测出工况Ⅰ、Ⅱ、Ⅲ下的静载应力,并在37.5t的检测载荷作用下,采用动态应变仪测出在检测工况下的动载应力,还对两种应力的检测结果进行了分析,结果表明:静载应力满足工作要求,动载应力不满足工作要求。
Take a double car material box bridge crane metal structure＇s stress testing of a steel company as an example. Using the static strain indicator measure the static load stress under the conditions Ⅰ , Ⅱ, Ⅲ, and in the 37.5 detection loads ,using dynamic strain indicator test dynamic stress in the detection conditions. Analying the test results of the two kinds of stress ,results show that： the static load stress meet the job requirements, the dynamic stress does not meet the job requirements.
