Abstract

The invention belongs to the field of devices, and particularly relates to a thermal deformation analysis method for thermodynamic coupling simulation of an automobile lamp reflector. The method includes data processing and extraction in a thermal simulation process; data processing and extraction in dynamic simulation; thermal coupling and solving of extracted data and post processing of a result, wherein the thermal coupling simulation result can reflect thermal deformation of the lamp reflector and evaluate the offset of a cut-off line, and the thermal deformation of the thermodynamic coupling simulation of the automobile lamp reflector is achieved by the united simulation technology. The method has the advantages of applying load and constraint to a finite element mesh model of a lamp,considering the thermal deformation of the lamp mirror and analyzing the offset of the cut-off line, thereby being more reliable and accurate compared with the traditional analysis method.

Description

technical field [0001] The invention belongs to the field of equipment, and in particular relates to a thermomechanical coupling simulation method for thermal deformation analysis of a car lamp reflector. Background technique [0002] With the rapid development of the automobile industry, car lights play a very important role in people's driving process. Now the relevant laws and regulations have higher and higher requirements for the lighting performance of car lights. Among automotive lamps, headlamps and front fog lamps have the function of adjusting far and near beams. The relevant regulations clearly stipulate the offset of the cut-off line of headlamps and front fog lamps. During driving, when the lamps are on, the height of the cut-off line will change. If the cut-off line is too high, it will dazzle the oncoming vehicles or pedestrians; Potential safety hazards; therefore, the stability of the cut-off line offset is of great significance to driving safety. [0003]...
