基于UG的曲柄滑块机构参数化设计的运动学仿真

摘要

随着计算机技术的飞速发展，CAD已经广泛应用于零件设计和制造中，但一般的CAD软件都具有广而博的通用性，难以满足各类具体产品设计的需要，所以以通用CAD软件为基础，根据本单位的实际，进行不同程度的开发成为产品现代设计的重要内容。

连杆作为各种机械传动设备中的重要装置，具有压强小，磨损轻，易于加工和保证加工精度，以及能有本身几何形状保证运动副封闭等优点，有着非常广泛的应用前景。但其较难准确的实现任意预期运动规律，设计计算亦较繁复。为了提高设计效率，增加竞争优势，实现曲柄滑块机构的运动的精确建模显得尤为重要。

文运用三维实体造型软件UG，实现了曲柄连杆机构参数化精确建模。文中系统地研究了运用UG软件方程输入的方式建立曲柄滑块机构的三维参数化模型的过程。由于参数化曲柄连杆模型可按照驱动参数的变化发生相应改变，所以利用此模型进行曲柄连杆的重复性工作，从而极大地提高了分析效率，降低了成本

Abstract

Because the calculator technique flies soon a development, CAD already extensively applied in the spare parts design and the manufacturing, but general of the CAD softwares all have wide but the in general use of the Bo, and is hard to satisfy each kind of demand that the concrete product designs, so take in general use CAD software as foundation, according to this unit of actual, carry on the important contents that the development of different degree becomes a product modern design.

Connecting the pole is various machine to spread the important device in the equipments, have to press strong small, wear away lightly, be easy to process and promise to process accuracy, and can have oneself several the shape promise sport pair closes to wait an advantage and have very extensive of applied prospect.But it more difficult accurate realization arbitrarily expectation sport regulation, design to compute as well more complicated.For raising a design efficiency, increase competitive advantage, carry out the accurate model of sport that the crank slips piece organization to seem to be is importance

The text makes use of 3D entity shape software UG and carried out crank to connect pole organization parameter to turn an accurate model.Systematically studied the 3D parameter that the way establishment crank of the usage UG software equation importation slips piece organization to turn the process of model in the text.Because the parameter turns crank to connect pole model can according to driving the variety occurrence of parameter to correspond a change, so make use of this model to carry on the repeated that the crank connects a pole to work, thus and biggest raised an analytical efficiency, lowered cost.

Keyword: The crank connects the pole UG parameter to turn
