小型豌豆收获机机架模态分析及优化设计

With independent research and development of maize interplanting mode and low damage/peas small pea harvester frame as the research object, using SolidWorks software to establish the three-dimensional entity model, and use the Block Lanczos method and ANSYS Workbench software analysis the peas machine frame under the original plan the first twelve modal frequency. Through ANSYS Workbench software analysis of the original scheme and the 10 second-order equivalent vibration type of the frame under the four optimization schemes, the weak links of the frame are discussed. The results show that the frequency error of each rank modal of Block Lanczos and ANSYS Workbench is kept within 2%. Will stand two fixed support optimization for symmetric structure, the optimization of the frame of the steel plate thickness 1 mm, peas, exports of the tank wall thickness optimization is 3 mm machine frame performance can keep most peas, and minimize the economic costs.
