    • 本研究針對支撐移動平台的線性滑軌，探討零件尺寸變異時導出尺度或特徵之可能偏差。研究首先推導滾柱變形量之尺度鏈，其次由經驗公式建立滾柱變形與受力的關係。之後以最差法、統計法與蒙地卡羅模擬法，分別推算滾柱受力之平均值與變異。研究中觀察到統計法與蒙地卡羅模擬法分析滾柱受力之差異，因而提出分離法作為滾柱受力之分析方式。此法能克服滾柱與溝槽間隙配合所造成統計法估算之誤差，並迅速有效的推算滾柱受力。

    Focusing on the linear guides with cylindrical rollers, this research studies the variations of key dimensions due to the tolerance of components. The dimension chain for the deformation of the rollers is derived first. Empirical formula is then used to describe the relationship between the deformation and force exerted on the rollers. Three methods, which are the worst case, statistic and Monte Carlo methods, are used to compute the mean and variance of the force on the rollers respectively. Since significant differences between the results obtained from statistic method and Monte Carlo method have been observed, it is recommend that the separate method be in the tolerance analysis of rollers. This new method can handle the interference fit between rollers and guide and estimate the force exerted on the rollers effectively
