Question

高分求翻译（汉译英）

安全性是制约民航工业发展的重要因素。一般飞机失事时，机身与地面接触后，巨大的冲击载荷不仅会使飞机机身本身结构损毁，而且也会对机舱里的乘客和货物造成很大的伤害。特别是客机，会对乘客的生命安全产生很大的威胁。因此，我们对飞机地板设计有了一种新的设计理念，即飞机在结构设计过程中需对机身地板下部结构有特殊的功能要求，即需要对机身地板下部进行抗坠撞设计。该设计可以保证飞机机身下部结构损毁以后，吸收大量的能量，使得座舱中的冲击惯性载荷大大减小，从而减少甚至消除对座舱内乘员的伤害。一般飞机座舱地板下部机身框与蒙皮相连的是一种“L”型的铰片，此结构一般被看做是飞机座舱地板下部主要的抗坠撞结构。但是实际中我们发现该结构的抗坠撞性能并不尽如人意，材料的比吸能也不高。为此，通过了解金属结构和复合材料结构能量吸收（耗散）的基本原理，掌握金属结构和复合材料结构机身框段坠撞条件下的响应特性和变形模式的一般规律，对抗坠撞性能较好，比吸能较高的圆筒和球壳结构做了充分的理论分析和仿真实验论证。并根据给出的原型结构和总体技术要求，完成地板下部结构元件的替换件的方案设计，包括：（1）替换件在地板下部的布局；（2）替换件的初步设计。最后，再利用有限元软件进行机身框段的坠撞仿真分析，完成破坏模式分析、响应特性分析和元件能量吸收效率分析（采用比吸能），并与原型结构的结果进行对比，获得关于地板下部结构抗坠撞设计有效性的相关结论。
第三行will not only make airplane itself, but also damaged structure of the cabin passengers and goods caused great damage这句语法对吗？

Answer 1

Security is an important constraining factor in the development of civil aviation industry. General crash, the body contact with the ground, the huge impact load will not only damage to the aircraft fuselage structure itself, but also on the cabin passengers and cargo caused great harm. Particular aircraft, the safety of the passengers will have a great threat. Therefore, we designed the aircraft floor, with a new design for aircraft structural design process need to lower the floor of the fuselage structure with special functional requirements that need to be on the lower part of the flying body hit the floor design. The design ensures the fuselage substructure damage after absorbing a lot of energy, makes the cockpit in greatly reduced the impact of inertial load, thus reducing or even eliminating damage to the cockpit crew. The lower part of the general aircraft cabin floor fuselage frame and skin attached to a "L" shaped hinge pieces, this structure is generally seen as the cockpit floor, hit the lower part of the main structure of the flying. But in practice we found that the structure of the anti-collision performance is not satisfactory fall, materials are not higher than the energy absorption. To this end, by understanding the structure of metal structures and composite materials energy absorption (dissipation) of the basic principles of control of metal structures and composite structure fuselage frame section fall under collision response and deformation modes of the general laws of the collision performance against falling better than the higher energy absorption structure of cylindrical and spherical shells made sufficient theoretical analysis and experimental demonstration. Prototype based on the structure and given the general technical requirements, complete the lower floor structural elements of the replacement parts of the program design, including: (1) replacement parts in the lower part of the layout of the floor; (2) the preliminary design of replacement parts. Finally, the finite element software to hit the fuselage frame section of the fall simulation, complete failure mode analysis, response analysis and component analysis of the energy absorption efficiency (using the ratio of energy absorption), and the results of the prototype structure are compared, was on hit the floor substructure design effectiveness of the flying conclusions.

Answer 2

Security against civil aviation industry to develop an important factor in the plane crash. generally, the contact with the ground after the impact loads of the fuselage itself, but also structural damage to the cabin passengers and goods caused great damage. in particular, the passenger safety of a big threat.We, therefore, to the floor to design a new concept that the plane in the design process needs to the floor behind the structure is of special features requirement, the need to carry out resistance from the floor below into the design. the design also ensures that the lower part of the structure of damage, in large amounts of energy, the cars over the impact of the inertial much reduced to reduce or eliminate the damage. the crew of the cars over。General cars over the floor of the box below the plane with your skin of a type of the "l", this structure is generally seen as the plane cars over the floor behind the main resistance against the sinker. but the actual structure we found that the structure of the falling into the performance never matched expectations, the material can be no higher than a metal. in this regard, through knowledge structure and consumption of energy absorption of composite construction part of the basic principle,The metal framework and composite construction of the box fell into the response and distorted patterns of general and rammed against riding performance and can better than a high drum and the shell structure made of theoretical analysis and emulation the argument. and according to a given structure and overall technical requirements, the floor behind the structure of replacement components of the design,Including ： （1） replace at the lower floor of the layout ； （2） replace two of the preliminary design. finally, the use of finite element into the box fell into the complete destruction and simulation model analysis, quality analysis and response elements of energy efficiency in analyzing （ the breath can ） and the result of a structure in contrast, on the floor behind the structure of resistance against the design from the relevant validity of conclusions.

Answer 3

Security is an important factor of the civil aviation industry development. Usually when the plane crash, airframe after contact with the ground, and the huge impact load will not only make airplane itself, but also damaged structure of the cabin passengers and goods caused great damage. Especially for passenger airliner, the life safety of a threat. Therefore, we design a plane floor of a new design concept, namely the aircraft in structural design process to lower fuselage floor with special structure, i.e. the function requirements of the fuselage floor needs for falling into design. This design can guarantee the damaged aircraft airframe, absorb large amounts of energy in the cockpit, impact inertial load greatly decreased, thus reduce or even eliminate the cabin crew. General aircraft cabin floor lower fuselage box and connected to the skin is a kind of "L" type reaming, this structure is generally considered the main floor of the cockpit of falling into structure. But we found the actual performance of structure is not satisfactory, sank into the material than can also is not high. Therefore, through the understanding of metal structure and composite structure energy absorption (principle of dissipative), metal structure and composite structures fell into fuselage box under the condition for the response characteristics of deformation modes and the general rule of fight fall into good performance and higher than to the cylinder and spherical shell structure made full of the theory analysis and simulation experiment. And according to the given prototype structures and overall technical requirements and finish the floor of the structural components, replace design include: (1) the replacement parts in the layout of the bottom floor, (2) to replace the preliminary design. Finally, using finite element software into the fuselage box fell for simulation analysis, complete failure mode analysis, the response characteristics were analyzed and the component analysis (using energy absorption efficiency than can), and the results of prototype structures, structural resistance on the floor of the effectiveness of the design sank into relevant conclusions

Answer 4

Security is an important constraining factor in the development of civil aviation industry. Generally , the body contact with the ground when cash, the huge impact load will not only damage to the aircraft fuselage structure itself, but also on the cabin passengers and cargo caused great harm.Particular aircraft, the safety of the passengers will have a great threat. Therefore, we have a new design concept with the floor of the aircraft , that is process need to lower the floor of the fuselage structure have special functional requirements that need to be on the lower part of the flying body hit the floor design.
