摘要
为了更好的提高汽车散热片的使用寿命。结合汽车散热片的结构利用SOLIDWORKS建立三维模型,基于ANSYS的基础上分析散热片的振动特性,找到散热片的薄弱环节,从而提出改进方案。首先将三维模型转化格式为通用格式(X-T)或(IGS),然后倒入到有限元ANSYS中进行网格划分,定义边界条件等前处理,分析散热片的静应力及模态振型变化。最后运用响应曲面优化分析方法(Response Surface)进行求解计算,依据分析结果进行结构改进,得到了最优的设计方案。
In order to better improve the service life of automobile radiator? Combined with the structure of the automobile radiator, the three-dimensional model is established by using SOLIDWORKS. Based on the ANSYS, the vibration characteristics of the radiating fin are analyzed, and the weak links of the heat sink are found, so an improved scheme is put forward? The first will be transformed into a general format of 3D model format(X-T) or(IGS), and then pour into the finite element mesh in ANSYS, define the boundary conditions of pretreatment, static stress and modal shape change analysis of heat sink. Finally, the response surface optimization method(Response, Surface) is used to solve the problem, and the structure is improved according to the analysis result? The optimal design scheme is obtained?
