Title  Design the Control System of Life Test Workbench for Ball Screw--Design of Software System         

Abstract

Aiming at the study for the life of ball screw, this issue has developed a kind of testing equipment for its life test in the background of a national major scientific and technological project, “Research of Roller Components Common Features Technology in High-grade CNC Machine (2012ZX04002021)”.In according to finish this study for ball screw, hardware system and software system should be built, test data should be collected and analyzed.

As the frequently used mechanical transmission products, ball screw can convert rotational motion into linear motion and convert linear motion into rotational motion. Its quality will directly affect the overall performance of CNC machine tools. Firstly, this thesis has raised the achievements and problems of research status in all over the world, and the prospect in the near future.

According to the requirements of the life test experiment for ball screw and understanding of the main performance parameters of laboratory apparatus, the hardware structure of the workbench is designed and the integral system is built.

On the basis of the completed life test workbench for ball screw, Visual C++ is used to develop the operating software to accomplish the human-computer interaction,analyze the data collected and print the data needed. Determining the algorithm, code and data structures of the internal modules, and generate its detailed documentation and debugging the software system on specific hardware system.

The software developed is used to accomplish the running process simulation and loading process simulation. On the basis of the completed life test workbench for ball screw, it is supposed to come up with specific suggestions to improve the life of ball screw from in-depth analysis of its comprehensive performance by collected experimental data on the workbench.
