【摘要】 利用LS DYNA作为求解器在HP C360工作站上完成了轴对称圆柱壳受高速热冲击作用的计算机模拟,得到了位移时程曲线和单元的应力时程曲线,并与已有的结果进行了比较,还得到了在不同边界条件下线热膨胀系数、热传导系数以及比热容对位移和应力的影响。为热冲击问题的进一步研究提供科学依据。更多还原

【Abstract】 By using LSDYNA as a solver, the simulation of the dynamic response of short cylindrical shell under thermal impact was carried out on HPC360. The curve of timedisplacement and time-stress was got from the caculation. The result was compared with the result of references. The influence of different boundary condition to linear thermal coefficient of expansion, thermal conduct coefficient and heat ratio coefficient was discussed finally.更多还原
