Linear rolling guide has gained wide application in various CNC machines. As a main joint of the machine tools, it makes great impact on the dynamic characteristics of machine tools. It is therefore necessary to study the dynamic behavior of linear rolling guide. And external load is a factor that affects the dynamic characteristics of linear rolling guide. In this paper experimental approach was used with the aim of studying effects of external load on dynamic behavior of linear rolling guide. The experiment contained some modal tests of linear rolling guide ways when they were loaded forces of different sizes.

The finite element model of grinding wheel carriage on glass edging machine was established, some key mechanical joints such as ball lead screw pair, linear rolling guide pair and lead screw bearing were simulated by combin14 spring-damp unit. The mode analysis was finished by ANSYS software, the frontal 4 modes and natural frequencies indicated that the weak part of grinding wheel carriage vibration was lead screw and assembly board of sliding block. The natural frequency and dynamic behavior of grinding wheel carriage will be improved by increasing diameter of lead screw and thickness of assembly board of sliding block, preloading lead screw bearing and ball lead screw pair, using middle or heavy preload linear rolling guide. The research result is very important for the design of large scale vertical glass edging machine.

Design resources reuse is very important to the rapid response design. In this paper, a design resources reusable model based on product family is established to meet the rapid response design. Firstly, parameters transmission structure of product family is constructed based on Generic Bill of Materials (GBOM) and product master model, and then the reused design resource library is established by the instantiation to master model. Finally product configuration management and variant design is realized on the basis of the reused design resource library. In the developing process of the rapid response design system of machine tool component, the Linear Motion (LM) rolling guide variant design subsystem is developed by the application of the above methods to realize the variant design and configuration management of LM rolling guide. The result shows that the method can provide a reliable guarantee for establishment and effective management of corporate design resource base.
