- Abstract
The main function of corn harvester frame is to bear loads from working parts, such as engine, cab, transmission, chopped header, husking machine. In this paper, three kinds of typical working conditions of corn harvester, namely, driving on uneven road at relatively high speed, braking and unloading, were researched. Then the most dangerous working condition was determined and used as a foundation to analyze the reliability of the frame. Based on reliability analysis results, it could be confirmed whether the structures of frame needed to be optimized. If needed, the sensitivity analysis results were applied as a support to optimize the structure parameters of frame. Based on above methods, the cross sections’ parameters of longitudinal beams and cross beams were optimized to satisfy the requirement of the frame mechanical properties. As a result, the weight of the frame decreased by 19.6%, which achieved the purpose of lightweight. It is concluded that this method is effective to reduce costs and improve efficiency in manufacturing processes. Furthermore, the method may be beneficial to improve the manufacturing level of harvesting machinery.
