连杆运动

Its motion domain can be separated as two boundary points or a direction changing point of boundary.

其运动领域可分离为连杆轨迹曲线上的两个边界点或边界转向点。

The membrane isolation pumps is one kind of hydromass transportation hydraulic system,can reduce the cartage expense greatly,but indirectly brings the huge social efficiency,safe reliable,the work rate is high,may not stop nearly carries on the whole year to transport,does not have the material to lose nearly,the easy automatic control,to be advantageous for the maintenance management The hydraulic pressure diaphragm pump is one kind of fill domestic diaphragm pump which we develops in high-pressured,the small curr ent capacity pulp transportation aspect blank pumps plants,it and the common diaphragm pump main difference is:Has substituted for the crank connecting rod,the reduction gear using the hydraulic pump and so on aseries of equipments direct drive piston motion,this causes its structure is greatly the simplification,the cost drops greatly;When at the same time also requests the piston the commutation confidential assurance extremely accurately,but must realize this point theoretically and all has the very great difficulty in fact.

膜隔离泵就是一种浆体输送的液压系统，能大大降低运输费用，可间接带来巨大的社会效益，安全可靠，作业率高，几乎可不停地进行全年输送，几乎没有物料损耗，易于自动控制，便于维护管理。液压隔膜泵是我们开发的一种填补国内隔膜泵在高压、小流量矿浆输送方面空白的泵种，它与一般的主要区别是：利用液压泵取代了曲柄连杆、减速器等一系列装置直接驱动活塞运动，这使其结构大为简化，成本大大下降；但同时也要求活塞的换向时机要把握得非常准确，而要实现这一点理论上和实际上都存在很大难度。

By means of the curcuit mapping transformation developed in electrical network analysis, it is proved that the total reaction forces and moments are not independent but ran be linearly represented by two sets of independent ones, namely, cotree forces and cotree moments, respectively.

本文根据研究内容不同分成两篇，第一篇提出了一种基于网络分析方法的平面连杆机构运动学和静力学理论研究体系，侧重探讨和揭示了机构运动和力分析数学模型的内在联系，研究了机构组成的计算机辅助识别原理、策略、方法及软件设计技术。

Since the planer was yet to be invented (in 1817), no means then existed to machine a long, straight guide to serve as a crosshead in the steam engine.

因为他在当时的蒸汽发动机上应用了直线连杆引导长的活塞上下运动的装置。

The direct numerical integration method was applied to obtain the steady state response of mechanisms with elastic links.

这不失为一种直接获得弹性连杆机构动态响应和机构真实运动轨迹的迅捷方法。

Based on the analytic model of an eccentric slider crank mechanism with elastic effects at both joints of the coupler and four coupler Mathieu-typed equations of motion in terms of the generalized coordinates of the system,the extract solution is developed from the improved Hill method with accelerated convergence.

在所建立的连杆接头处具有弹性效应的曲柄滑块机构的动态解析模型以及在广义坐标下推导出的4个马修型运动方程的基础上，由具有加速收敛性的改进希尔法进行了精确求解。

The crank and connecting rod mechanism, the cam mechanism and the eccentric wheel mechanism are used to transform the continuous movements into the reciprocal movements, yet these mechanisms have no constant transmission ratio and there exist rather large impact force while operating at high speed.

曲柄连杆机构、凸轮机构和偏心轮机构常用来将连续运动转化为往复运动，但这些机构没有恒定的传动比，高速运转时存在较大的冲击力。

A new way of exchange between rotation and reciprocating motion through planetary driving was introduced, which was different from the one realized by piton pump moving with cam, brace and link.

采用行星齿轮传动方式实现从旋转到直线的往复运动，不同于现有柱塞泵由凸轮、曲柄连杆或斜盘实现往复运动的方式，没有滑靴等高压力作用下高速滑移的元件。

In this paper the size of the crank-slider mechanism is synthesized,and the point location is correctly selected for the six-bar linkage mechanism.

对于这种轨迹串联的组合机构，由于后一基本机构的运动，取决于前一基本机构中从动件的轨迹，要求连杆上M点作一过从动件的固定铰接点D的一段直线，从而使构件DM可以作间隙的旋转运动。

The procedures of design and analysis of this mechanism is very complicated if individual graphic means or math analysis is used, So MAPLE was used in kinematical design and kinetic analysis of six-bar mechanism.

在进行该机构的设计和运动分析时，单独使用图解法或解析法其过程都十分繁琐，因此采用MAPLE对六连杆打纬机构进行动态设计和运动分析。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
