| China is the world’s third-largest grower of sugar cane, in the 2013/2014 crop acreage up to 2805 million mu, and the cultivation was a significant growth trend. However, the mechanization of sugarcane is very low, in Guangxi Province as an example, sugarcane acreage accounted for more than 60 percent of China’s total sugar cane cultivation, but mechanized planting operations was only 6%. At the same time, in many areas there are already parts of the sugarcane migrant workers, which makes a large area of artificial shortages forcing the labor costs have been greatly improved, compared to previous years in planting season. Therefore, an urgent need to develop a good performance in line with China’s national conditions and sugarcane planter.This paper is according to the actual needs of an enterprise, and enterprise related research and development engineers to develop a foothold in the reality of our country national condition, breaking the traditional hydraulic-driven approach, based on ground-wheel drive sugarcane planter.First of all, access to a large number of sugar agricultural standards and sugarcane planting machinery industry standards, and sugarcane planting machine data in China and abroad. And field trips sugarcane cultivation in Guangxi province, to determine the machine key structure layout and various parameters, such as drive form, cane varieties feeding and cutting way. Separately for each feature in detail design and assembly to complete the overall design. Draw three-dimensional drawings, and supporting the completion of the first generation prototype of the trial and assemblySecondly, using the finite element analysis to check the sugarcane planter frame strength. The use of HyperMesh model simplification, geometry cleanup and meshing, complete the finite element model of the rack of pre-treatment. And according to the loads and constraints of several typical working conditions, using the Radioss solver to solve the condition of the structure the maximum stress is 166MPa and the maximum displacement is 10.82mm, obtain stress distribution and displacement distribution nephogram, meet the design requirements of structure performance. And solving the frame free modal vibration mode and natural frequency, verify that no resonance occurs with the tractor.Thirdly, testing the first generation prototype sugarcane planting performance in the province of Guangxi Longan test site, and get a lot of planting performance data. Through the collation and analysis, to complete the performance appraisal of the first generation prototype, planting performance can basically meet the design requirements. At the same time, analyzed and validated problems in the performance test of planting, give some advices, for the next generation of models presented design ideas.Finally, according to the results of finite element analysis, choose the main frame and the small frame of sugarcane planter as the optimization object to lightweight design. Base on the HyperMesh OptiStuct module,determine the thickness of each parts in the main frame and the small frame as optimization design variables,, objective function is to minimize the total volume. By optimizing the design, quality of the main frame and the small frame are reduced greatly, the initial mass is 413kg, after the optimized mass is 320.1kg, weight loss reached 92.4kg, the quality of the original weight accounted for 22.40% of the total mass. At the same time, the results can meet the requirements of the performance of the structure, so the whole frame structure optimization design has completed the requirements of lightweight design.
