Abstract:

通过两种有限元模型的对比,提出了符合实际的X-cor夹层结构压缩模量有限元计算模型,利用大型有限元软件ANSYS对其压缩模量进行了数值计算,得到了X-cor夹层结构的应力场和压缩模量。研究了Z-pin半径、密度、植入角度和体积分数的改变对模型压缩模量的影响。结果表明X-cor夹层结构压缩模量随Z-pin植入角度增加而减小,随Z-pin半径、密度和体积分数增加而增加,且与Z-pin体积分数呈线性关系,改变Z-pin半径与改变Z-pin密度对X-cor夹层结构压缩模量影响是等效的。通过有限元模型的计算,得到了X-cor夹层结构参数对其压缩模量的影响规律,验证了所提有限元模型的合理性。
