外文摘要：[Objective]The main component of the drum type residual film recovery machine is prone to heap soil and deformation in the process of operation.It is of great significance to monitor its stress and strain,improve the working efficiency of the residual film recovery machine and reduce the failure rate of the residual film recovery machine.[Methods]The strain monitoring system of soil teeth was designed,the monitoring point was determined by ANSYS analysis,the sensor was calibrated by DH5922N data analyzer,and the strain signal acquisition unit measured the stress and strain of the small deformation of soil teeth,realizing the contin-uous monitoring of the stress and strain data of soil teeth,and giving early warning to the overloading condition of soil teeth rake.[Results]The real-time monitoring of stress and strain of the pine rake could be carried out effectively,and the field operation speed was simulated.The mild overload threshold was determined to be 140 Mpa,and the severe overload threshold to be 180 Mpa.The overall average relative error of the monitoring results was 10.12%.[Conclusion]The stress and strain monitoring system of soil rake is mainly composed of six parts:Microprocessor,strain signal acquisition unit,AD analog-to-digital conversion,power module,communication module and cloud platform visual interface.
