The present invention proposes a method for optimizing an EGR engine cooler based on finite element analysis, comprising the following steps: modeling the designed EGR cooler with UG; setting the parameters of cooler parts to be optimized as driving parameters; Divide; import the model into the ANSYS STATIC STRUCTRAL module, and use the stress as an output parameter; connect the RESPONSE SURFACE OPTIMIZATION module; select three to five sets of design points for each driving parameter; update the design points for calculation; apply actual loads to solve; When the output parameters are satisfied, the design parameters of the EGR cooler adopt the optimized parameters; after the optimization is completed, new design parameters are determined. The invention adopts the method of finite element, uses ANSYS to simulate and optimize the engine cooler, and optimizes the multi-parameters under the condition of meeting the design strength, which can effectively reduce the workload and improve the accuracy of design analysis.
Description
technical field [0001] The invention relates to the field of simulation design, in particular to an optimization method for an EGR engine cooler based on finite element analysis. Background technique [0002] The diesel engine has the characteristics of low fuel consumption and high efficiency, and has good economy and power. Experiments have proved that the diesel engine can save energy by 18% to 28% more than the gasoline engine. Since the price of diesel is lower than that of gasoline, the diesel engine can save fuel costs by 33% compared with the gasoline engine. %~40%. Therefore, the diesel engine of modern technology is gradually becoming the main vehicle power in developed countries in Europe and America, and the dieselization trend of vehicle power in this century has also become the consensus of the international automobile industry. [0003] However, it is an indisputable fact that research on diesel engine emission technology lags behind that of gasoline engines....
