利用有限元法建立了力传感器的动力学方程。利用该模型就各因素对传感器动载输出的影响进行了仿真分析, 从而对检疲劳机动负荷用力传感器“静标动用”检定方法的误差有了定性和定量的认识。关键词: 疲劳机; 有限元法; 力传感器; 动态Abstract: The dynam ic equat ion of fo rce t ran sducer is set up by u sing the FEM in th is ar t icle. The sim u lat ing analysis of several effect s on the dynam ic ou tpu t of t ran sduc2 er are m ade in term s of the model. A nd then the know ledge of the er ro r w h ich is cau sed by calib rat ing stat ically w h ile u sing dynam ically of fo rce t ran sducer fo r calib rat ing the dynam ic load of fat igue m ach ine is acqu ired.Key words: fat igue m ach ine; FEM ; fo rce t ran sducer; dynam ics
