With the continuous improvement of the national economy,the demand for high-quality edible oil is increasing,which indirectly promotes the growing amount of Camellia oleifera in China.At present,the current situation of Camellia oleifera tending in China is mainly manual and mechanical operations.At present,this part of mechanized operation has many kinds of mechanical equipment,one machine and one use,and poor general compatibility,which leads to low efficiency of oil tea tending and low quality of operation.The oil tea dynamic chassis is a multifunctional working equipment which can be replaced by a working module.It solves the problem of many working procedures in the process of Camellia tending and the problem of many necessary equipment,with the least kinds of operating equipment and the optimal general module group,and the maximum efficiency of the tending machine operation,thus the best work of the oil tea tending is realized.Industry to promote the mechanization of Camellia oleifera continue to grow and grow.As the core component of Camellia power chassis,the strength and stiffness will directly affect the efficiency of Camellia power chassis,and its characteristics are very necessary.This paper first introduces the research status and development trend of Camellia power chassis and its working arm,and then briefly introduces the power chassis system of Camellia oleifera.The virtual prototype of the power chassis working arm is established by using SolidWorks modeling software.Then the basic structure and working conditions of the working arm are briefly introduced.At the end,the maximum forward resistance and maximum lift resistance of the operating arm under positive load,positive load,partial load and partial load are calculated respectively.The theoretical basis is provided for the follow-up analysis,and the equivalent effect of the lifting arm under the positive and partial load conditions is calculated.Secondly,the ADAMS simulation model of the operating arm under the positive and partial load conditions is established respectively,and the simulation calculation of the ADAMS simulation model under positive and partial load conditions is carried out.The force course curve of the lifting oil cylinder and the overturning cylinder under the positive load and the partial load condition and the stress history curve of the key hinge points of the manipulator are obtained.The finite element analysis software SolidWorks Simulation is used to create the finite element model of the operating arm and analyze the finite element model in four working conditions.The stress distribution,the displacement cloud and the stress distribution of the key members of the working arm are obtained.According to the results of finite element analysis,a structural optimization scheme is proposed for the flipper arm.The results show that the maximum stress value of the overturned arm decreases obviously after the optimization,and the rationality of the structure optimization is verified.Finally,the chassis working arm was tested.The experimental data show that the relative error of the test results is within 10%.It is within the scope of the actual process level and the machining error.The results of the test arm stress test results agree with the results of the finite element analysis,and the rationality of the design and calculation of this paper is verified.
