    摘要:

    為了提高微傳動平臺的定位精度,，對幾何誤差進(jìn)行了分析。利用微分關(guān)系構(gòu)造微傳動平臺輸出位姿誤差與各結(jié)構(gòu)參數(shù)幾何誤差之間的映射關(guān)系,，引入誤差權(quán)重系數(shù),，分析了各結(jié)構(gòu)參數(shù)對微傳動平臺定位精度的影響,，建立了微傳動平臺的精度補(bǔ)償模型。利用Matlab對微傳動平臺的定位精度進(jìn)行計算仿真,，搭建實驗平臺進(jìn)行實驗測試,，仿真和實驗結(jié)果表明，基于權(quán)重系數(shù)法建立的誤差模型合理,，并且通過建立的精度補(bǔ)償模型,，微動平臺的定位誤差從補(bǔ)償前的20%~30%下降到了補(bǔ)償后的10%~15%，使微傳動平臺的定位精度獲得了較大提高,。

    Abstract:

    In order to improve the positioning accuracy of micro transmission platform, the geometric errors were mainly analyzed. The mapping relationship between output pose errors of micro transmission platform and geometric errors of structural parameters was built through the method of differential relationship. And then the influence of structural parameters on the micro transmission platform positioning accuracy was analyzed by introducing the error weight coefficient, and the precision compensation model of micro transmission platform was established. Then a simulation calculation through Matlab software and an experiment test on the experimental platform were carried out. The results of simulation and experimental test showed that the error analysis model based on the weight coefficient method is reasonable, and what’s more, through the established precision compensation model, the micro transmission platform’s positioning error descended to 10%~15% after compensating, which was 20%~30% before compensating, and that made the micro transmission platform achieve a higher positioning accuracy.
