車輪不圓
英文
wheel out of round-
At one time complex structure and area of weariness crack ( including whole suspension hollow axis of swivel, half suspension adopted axletree, substituting holistic grinding steel wheels for wheel - hoop compounded wheels, different wheel - axletree structure of different locomotives, different transmission chamfer machining step of axletresses and driven traction gear etc. ) centralizing make wave clutter and repeat to disturb recognition of real fault wave
同時，由於全懸掛空心軸、半懸掛抱軸承等復雜結構車軸的使用和整體碾鋼輪陸續替代輪箍組裝式車輪，各型機車輪軸結構不同，車軸加工臺階和過渡圓角不同，從動牽引齒輪與車軸採用過盈裝配等，在這些結構復雜且疲勞裂紋產生集中的區域，探傷時極易發生波形交織和重復，難以識別真正缺陷波。A general stack equation of mobile robot based on analyzing the motion of planar motion object and the mathematical models of four different kinds of common wheels is developed, accordingly, the mobility of mobile robot is addressed and the forward and inverse solutions to speed for specific configuration driven by differential speed are derived. utilizing the muir and newman convention, the description of the posture transformation matrices between different coordinate frames and the solution for the speed of point located on these frames are introduced. according to posture estimation, a more accurate method, dead reckoning algorithm, is developed for a specified configuration characterized by differential speed motorization, and simulations of this algorithm and other traditional methods are carried out using matlab while traversing a circular path
本文對兩輪差速驅動移動機器人的運動學及其本體緩沖設計進行了探討，在對平面運動物體運動分析的基礎上結合四種常用車輪的數學模型，推導出了一個通用的移動機器人堆積方程，在此基礎上分析了移動機器人的移動能力、並針對兩輪差速構型推導了速度正解與逆解；使用muir和newman的運動學建模方法，推導了移動機器人上點及連桿坐標系位姿、速度變換關系矩陣及求解方法；在移動機器人位姿識別方法中結合差速驅動構型對航位推演算法進行了分析：推導了一種理論精度較高的航位推算演算法，並使用matlab對其與傳統的推算演算法在跟蹤圓弧軌跡情況下進行了模擬；最後針對本文所研究的機器人給出了一種比較系統、可靠的緩沖結構設計思路，較好地解決了移動機器人作業過程中外界因素及本身設計中引入的各種不確定誤差問題；本論文研究成果已在本實驗室所開發的樣機上得到實現，經過應用與考核證明其中的分析與設計是切實可行的。Analyze item by item the position of unintact cycle, the running clearance of unintact cycle, locking - deform, datum dimension regulating, repeatly install, power voltage wave and marking running etc. at the same time, we give the calculating formula to calculating the running marking random error, and use it to calculate the system error of big diameter measure instrument - - datum dimension frame error, gyro - wheel diameter error, error caused by circumstance temperature, error caused by backing distance, angle error, delay error of data collecting circuit, lathe main shaft running error, workpiece install partial error
對不完整圓的位置、不完整圓的轉動間隙、鎖緊變形、基準尺調整、重復安裝、電源電壓波動、標記轉動等隨機誤差進行了逐項分析，並給出轉動標記隨機誤差的計算公式。對大直徑測量儀的系統誤差?基準尺尺架誤差、滾輪直徑誤差、環境溫度引起的誤差、後退距離引起的誤差、角度誤差、數據採集電路延時誤差、車床主軸回轉誤差、工件安裝偏心誤差分別進行了計算，最後對誤差進行合成。
