Research On Standardization Of Vehicle Performance Design Planning

In the process of small batch transformation of the vehicle in the company,a large SUV model is used as a prototype.During the restructuring process,the front and rear suspension parts of the chassis were removed together on the prototype car and the sub frame.After the body appearance was rebuilt and assembled again,the relative assembly relationship between the suspension rods did not change.The steering system did not separate from the sub frame.The driving deviation of the car is a problem frequently occurring in the new production model,and its causes are complex and varied.In the analysis of the problem,the relevant requirements of the national standard and the standard of the enterprise were investigated,and the problem was confirmed by the sampling comparison of the non running and running vehicles.Analysis of four wheel positioning without obvious cause deviation of the law,in the actual track chassis disassembly and re assembly process,the suspension assembly positioning design,installation and installation of bolt size hole with the possible causes of assembly error,suspension assembly found without the use of positioning holes,assembly error caused by excessive vehicle wheelbase a large deviation and leads to deviation.To solve the problems in the stage,and is a production unit together to determine the suspension removing protection scheme,body protection scheme and the positioning hole transport Suspension Suspension re assembly technical requirements;communication and debugging unit,the principle of fully adjusted four wheel positioning on the suspension,the mistake was corrected,the following four wheel positioning adjustment the process and effect of weight,weight change thoroughly on the adjustment of this type of vehicle four wheel alignment;discusses SUV models for large deviation of the standard and final inspection unit.Through the above work,the problem of deviation in the process of the model modification is corrected,which lays a foundation for the subsequent batch production.Through the study of the system oriented product design planning theory,the vehicle driving performance design plan is perfected and the design standardization theory is put forward.
