【摘要】：随着科技的进步和社会信息化的不断发展,对产品的规模和复杂程度的要求不断提高,企业间的竞争日益激烈,传统的制造与设计已经很难适应当前企业的发展需要。因此信息技术应用于新产品研制以及实施途径的改造,是现代企业生存、发展的必然结果。在这种状况下,为了提高企业的效率和效益,改进和更新产品的开发模式是当务之急。本文以CATIA软件为二次开发平台,使用VBScript作为编辑工具,对减速器进行参数化设计和自动虚拟装配。利用SimDesigner for CATIA V5和Pro/E软件把虚拟样机导入到动力学分析软件ADAMS中,建立了减速器的多刚体虚拟样机系统,具体研究工作如下： 1.在CATIA软件中,应用VB编程功能编写程序,生成齿轮模型。由于齿轮传动减速器应用比较广泛,为了提高减速器的生产效率,缩短生产周期,提高产品在市场上的竞争力,由此开发出齿轮库和标准件库。根据用户需要,只需输入所需零件的基本参数,便可相应地生成所需的模型。 2.基于VB编程,把减速器的零件及附件进行全自动虚拟装配,然后进行干涉分析与检测。 3.利用插件SimDesigner for CATIA V5和Pro/E软件把减速器虚拟样机导入到ADAMS中,并对其传动部分施加约束和载荷,以便进行动力学仿真以及对仿真结果进行分析,即三根轴的转动角速度,得到输入轴、中间轴和输出轴的转动角速度随时间变化曲线,把用两种方法得到的仿真值与理论值进行比较,分析误差,进一步说明用两种方法导入到ADAMS软件中的可行性和减速器设计的合理性。
[Abstract]:With the progress of science and technology and the continuous development of social information, the demands on the scale and complexity of products are constantly raised, and the competition among enterprises is becoming increasingly fierce, so it is difficult for traditional manufacturing and design to adapt to the development needs of current enterprises.Therefore, the application of information technology in the development of new products and the transformation of implementation ways is the inevitable result of the survival and development of modern enterprises.In this situation, in order to improve the efficiency and efficiency of enterprises, it is urgent to improve and update the product development model.In this paper, using CATIA software as the secondary development platform and VBScript as the editing tool, parametric design and automatic virtual assembly of the reducer are carried out.Using SimDesigner for CATIA V5 and Pro/E software, the virtual prototype is imported into the dynamic analysis software ADAMS, and the multi-rigid virtual prototype system of reducer is established. The specific research work is as follows:1.In CATIA software, VB programming function is used to program and generate gear model.In order to improve the production efficiency, shorten the production cycle and improve the competitiveness of the products in the market, the gear storehouse and the standard parts library are developed because of the wide application of the gear drive reducer.According to the needs of the user, the required model can be generated by simply inputting the basic parameters of the required parts.2.Based on VB programming, the parts and accessories of reducer are assembled by automatic virtual assembly, and then interference analysis and detection are carried out.3.The virtual prototype of the reducer is imported into ADAMS by the plug-in SimDesigner for CATIA V5 and Pro/E software, and the driving part of the reducer is subjected to constraints and loads, so that the dynamic simulation and the analysis of the simulation results are carried out, that is, the rotation angular velocity of the three shafts.The rotational angular velocity curves of input shaft, intermediate shaft and output shaft are obtained. The simulation value obtained by two methods is compared with the theoretical value, and the error is analyzed.The feasibility of importing two methods into ADAMS software and the reasonableness of reducer design are further explained.
