Cylinder body reinforcing plate optimization method and device, electronic equipment and storage medium

Abstract

The invention discloses a cylinder body reinforcing plate optimization method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining an initial performance index of an initial cylinder body, the initial performance index comprising a modal parameter, a vibration parameter and a noise parameter; determining an index to be optimized based on the initial performance index and an expected target, wherein the index to be optimized comprises a modal parameter correction value, a vibration parameter correction value and a noise parameter correction value; determining a structural design variable of the reinforcing plate by using the to-be-optimized index; based on the mass constraint condition of the reinforcing plate and the to-be-optimized indexes, optimizing the structural design variables by utilizing optimization analysis to obtain manufacturing parameters of the reinforcing plate, and the manufacturing method can be used for the vibration and noise reduction design process of the cylinder body reinforcing plate of all diesel engines and can meet the requirements for light weight and NVH (Noise Vibration and Harshness) performance.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an optimization method, device, electronic equipment and storage medium for a cylinder block reinforcement plate. Background technique [0002] With the emission upgrade, the design explosion pressure continues to increase. If the rigidity of the cylinder block as a whole or a specific area is insufficient, abnormal vibration and noise of the whole machine will often occur, resulting in customer complaints or the NVH design index cannot be met at all. Due to the contradiction with the lightweight index of the whole machine, it is a difficult problem to ensure the excellent vibration and noise of the whole machine by designing the gantry type cylinder block with or without the cylinder block reinforcement plate and how to design it. [0003] Therefore, how to optimize the cylinder block reinforcement plate to reduce vibration and noise has become an urgent technical problem to...

Problems solved by technology

[0002] With the upgrading of emissions, the design explosion pressure continues to increase. If the rigidity of the cylinder block as a whole or in a specific area is insufficient, there will often be abnormal vibration and noise of the whole machine, which will cause customers to complain or fail to meet the NVH design indicators at all.
