机械与液压的发展前景(中文4300字,英文2600字)
随着人类社会的不断发展，陆地可开放资源日渐枯竭，世界各国逐渐将目光转向海洋，海洋资源的开放及利用对各国的发展起到了越来越重要的作用。由此引起的国家及地区间争端、摩擦不断。进入新世纪以来，随着海洋岛礁及资源争夺的加剧，海上运输线安全形势日趋恶化，海上利益争夺的形势将更加严峻，尤其是美、日、俄、印等国家，为壮大海军采取多种措施，已出现群雄争锋的局面。在全面实施海洋开放的时代背景条件下，海军肩负着维护国家安全，捍卫主权、维护国家海洋权益的神圣使命。
同时由于我们国家日益发展的经济情况还有我们日益强大的军事技术，我们和外界的联系也渐渐的紧密起来了。但是由于我国有着较为宽广的港口领域，所以海上交通便是我们和外界取得联系的最好方式。但是海上交通就一定会用到轮船，而与陆地取得联系就一定要用到跳板了，所以我便对这种跳板装置进行了一些设 计。跳板作为自行轮船重要的组成部分，可以在轮船靠近岸边时，可以作为被保障装备通行的桥梁。
现实当中我们看到的登船梯给我们的感觉是很笨重，不方便，如果用于游船是可行的，但是如果用于航母或军舰的话，那肯定不能符合使用要求了（一旦码头情况不允许那就会带来麻烦），所以必须研制出一种既轻巧方便又安全能适应军用的登船梯系统，这就是我的课题所要做达到的要求。
The prospects for the development of mechanical and hydraulic
With the continuous development of human society, the land could be open resources depleted, the world is gradually turning to the ocean, open and use of marine resources has played an increasingly important role in the development of countries. Disputes between countries and regions of the resulting friction. Since the beginning of the new century, with the ocean reefs and the scramble for resources intensifies, sea lanes security situation deteriorating situation of the competing interests at sea will be more severe, especially in the United States, Japan, Russia, India and other countries for the growth of the Navy adopted a multi- kinds of measures, warlords contend situation. In the era of full implementation of the open sea background conditions, the the Navy shoulder the sacred mission to safeguard national security, to defend its sovereignty, safeguard national maritime rights and interests.
At the same time due to the growing economic situation of our country and our increasingly powerful military technology, and the outside world has gradually close up. However, China has a relatively wide field of ports, maritime transport is the best way to contact the outside world. Maritime traffic will be used in ships, land contact must use the springboard, so I will be the springboard device design. Springboard as their own ship an important part of the ship close to the shore, can be used as the access bridge support equipment. |
