Abstract

The escapement is a very important horological invention and it is commonly used in theory of clocks and chronometers. It transfers energy to the timekeeping element and allows the number of its oscillations to be counted. The chronometer detent escape- ment used in marine chronometers was modified and simplified by Thomas Earnshaw, English renowned watchmaker, in order to make it available to the public. This chapter deals with 3D modeling and assembling of all escapement parts in SolidWorks, as well as constructive geometry of mechanism and computer simulation. The whole process has been accomplished in program “SolidWorks 2016,” where all parts are assembled by using standard mates since this approach is suitable for motion and dynamical analysis. Generated simulation results are very close to the real ones, thereby using computation ally strong kinematic solvers.

建模，运动研究，和计算机模拟的托马斯·恩肖的计时器扣擒纵机构

擒纵机构是一项非常重要的钟表发明，它通常用于钟表和计时器的理论。它将能量传递给计时元件，并允许计算其振荡的次数。英国著名制表师托马斯·恩肖(Thomas Earnshaw)对航海时计中使用的计时器防扣逃逸装置进行了改进和简化，以便于公众使用。本章讨论了在SolidWorks中所有擒纵机构部件的三维建模和组装，以及机构的构造几何和计算机仿真。整个过程已经在“SolidWorks 2016”程序中完成，其中所有部件都通过使用标准配件组装，因为这种方法适用于运动和动力学分析。生成的仿真结果与实际结果非常接近，因此可以使用计算能力较强的运动学求解器。

期刊介绍： The ACM Transactions on Modeling and Computer Simulation (TOMACS) provides a single archival source for the publication of high-quality research and developmental results referring to all phases of the modeling and simulation life cycle. The subjects of emphasis are discrete event simulation, combined discrete and continuous simulation, as well as Monte Carlo methods. The use of simulation techniques is pervasive, extending to virtually all the sciences. TOMACS serves to enhance the understanding, improve the practice, and increase the utilization of computer simulation. Submissions should contribute to the realization of these objectives, and papers treating applications should stress their contributions vis-á-vis these objectives.
