| Popis: | 96 Due to the improvement of machining quality, the demands of high performance of machine tool have been increased in recent years. Hence, the requirements for high machining precision gain a lot of intentions by the customers and machine makers. To improve the precision of machine tool, most companies have made their efforts on developing new model or doing optimization design on their origin designs. One of the key issues that cause the precision problem is the displacement between the spindle head and the platform. The relative displacement between the spindle head and platform will vary due to the effect of loading and vibration. Hence, in this thesis, the relative displacement between spindle head and platform due to loading and vibration will be studied. The mathematic model analysis is performed in the first beginning. A simplified model is then constructed according to its volume and weight. The cantilever beam and simple beam are then used for model analysis. The analyzing results are then being used for comparison between theoretical values and analysis values. According to the verification results, the causing of errors will then be discussed for future improvements and for further studies. |
