碩士 === 中原大學 === 機械工程研究所 === 92 === This paper discusses the effects of the missile that enters into the <a href="http://www.ntsearch.com/search.php?q=water&v=56">water</a>. Using the LS-DYNA <a href="http://www.ntsearch.com/search.php?q=software&v=56">software</a> to simulate the dynamic course of the missile. By analysis and compare impact of the missile that totally enters the <a href="http://www.ntsearch.com/search.php?q=water&v=56">water</a> with different angle and speed, we can get the axial <a href="http://www.ntsearch.com/search.php?q=stress&v=56">stress</a> of the missile. By this process to judge if the missile deforms. The simulation of the impact of the missile totally enters the <a href="http://www.ntsearch.com/search.php?q=water&v=56">water</a> of conditions. The initial condition of <a href="http://www.ntsearch.com/search.php?q=water&v=56">water</a> entry angle are 0 and 10,and the speed are 70m/s,80m/s and 90m/s. Then to analyze the maximum of axial <a href="http://www.ntsearch.com/search.php?q=stress&v=56">stress</a>, the speed of body totally enters the underwater, the change of acceleration and the <a href="http://www.ntsearch.com/search.php?q=time&v=56">time</a> of missile totally enters the underwater.
