The fourth chapter talks about the weft carrier, in this part, we mostly introduce the big gripper shuttle in the comparative way and not only analyze the structure but also analyze the stress of the fatigable parts. In the fifth chapter, the shuttle box is our research emphasis, we start with the design principle and analyze its structure and the logic of the action of the parts. The sixth chapter discusses the shoot mechanism, builds its theory model and analyzes its law of motion from the view of kinematics and kinetics during the wefting. And then, we can consider the hydraulically shoot mechanism and comprehend its principle and some special parts. Subsequently, the content is about the flying of a shuttle, because the course of the flying of a shuttle is very complex, it is necessary to study the shuttle according to mechanics and to analyze its course of motion and its change of speed from the view of energy.

第五章谈的是梭箱，这部分从梭箱的设计原理入手，从结构的角度对梭箱进行分析，考虑到梭箱上各执行件间的动作存在一定的逻辑关系，还对执行件动作时间与控制作出论述，从中可以看出重型宽幅织机所独有的特性；第六章论述投梭机构，先构造出投梭机＿重型宽幅织机引纬机构与梭箱的设计＿构的弹性理论模型，从动力学的角度剖析投梭规律，随后分析液压式投梭的工作原－－理和一些特型元器件；第七章论述梭子的飞行运动，考虑到梭子飞行运动的复杂性，我们把梭子飞行运动划分为三个阶段，然后分阶段介绍其运动规律，在对梭子进行＿运动分析的同时还详细分析它的受力情况，在这一章的最后，我们对影响梭子飞行＿的因素也作出了讨论；顺沿这一过程，即是第八章对制梭机构的论述，在这一部分，、主要研究制梭过程与制梭力的情况，同梭子飞行过程一样，制梭过程也分为三个阶段，就每个阶段而言，我们都对其进行受力与运动方面分析，同时也就一些容易出现的问题作出讨论；最后两章是对纬纱交接机构和纬纱的退绕与张力控制作出讨＿论，鉴于这两部分不存在复杂的动力学方面的问题，论述重点便放在结构与原理的分析上面，包括分解纬纱交接机构，解析其动作过程，介绍储纬与纬纱张力的一些情况。

In this thesis, we mainly expatiate on the design of the wefting mechanism and the shuttle box of the heavy wide loom, the prototype is JURGENS loom and we subdivide the wefting mechanism and the shuttle box in the modular way. There are shuttle box, weft carrier, wefting mechanism, braking mechanism, abb joining mechanism, unreel and tension control mechanism and so on.

因此，本文论述的重点便放在重型宽幅织机的引纬机构与梭箱部分，设计中以JURGENS织机为原型，采用模块化的方式细分引纬机构与梭箱，其中包括梭箱、引纬器、投梭机构、制梭机构、纬纱交接机构以及纬纱的退绕与张力控制机构等部分。

In even twill fabrics, the filling yarns pass over and under the same number of warp yarns, whereas in uneven twills the pick goes over either more or fewer warps than it goes under.

对于双面斜纹织物，处于纬纱之上和纬纱之下的经纱根数是相同的。而对于单面斜纹织物，处于纬纱上面和纬纱下面的经纱根数是不同的。

On this basis, the range of weft density on loom within which receding or moving forward of wefts will not occur is determined, and the method to calculate the number of receded wefts and their front-side warp angles at receded position are given.

在此基础上，构建了纬纱不发生回退及前移的上机纬密范围，给出回退纬纱根数及回退终了位置各回退纬纱前侧经纱角的计算方法。

For tightening and receding of wefts, the conditions under which wefts recede from the back beam and move forward towards the front beam relative to warps are developed by combining equilibrium condition of forces of warp with critical slip condition of weft.

针对纬纱的打紧与回退问题，将经纱的力平衡条件与纬纱的临界打滑条件相结合，建立了纬纱相对于经纱向后梁一侧回退及向胸梁一侧前移的条件。

The mechanism that the newly woven-in weft drives the receded weft to be beaten tight again during beating-up is analyzed. The process calculating back-side warp angles of receded wefts at tightened position is presented, and then a formula of displacement that receded weft slips from receded position to tightened position is given.

分析在被钢筘打入织口的过程中新织纬驱使回退纬纱重新打紧的机制，说明回退纬纱被重新打紧时其后侧经纱角的计算流程，进而给出了回退纬纱从回退终了位置运动到打紧位置的位移算式。

V max is the same at the period of insertion , two rapiers hand over weft at the maximum velocity , the curve of weft velocity and weft tension are formed single peak .

两剑在速度近似为最大值时进行纬纱交接，纬纱速度和纬纱张力都呈单峰型

Filling stop forks may be placed in the center of the lay, in which case it is known as a center fork, or at the side of the lay between the shuttle box and the reed , in which case it is known as a side fork.

纬纱叉可以安置在筘座的中部，称为中央纬纱叉；也可以安置在筘座的一侧，位于梭箱和钢筘之间，称为边侧纬纱叉。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
