3DT-420型 三軸光電轉(zhuǎn)塔電動測試轉(zhuǎn)臺【慣性導(dǎo)航測試轉(zhuǎn)臺】
產(chǎn)品簡介 Product introduction
慣性導(dǎo)航測試轉(zhuǎn)臺系統(tǒng)/Inertial Navigation Test Turntable System
慣導(dǎo)測試轉(zhuǎn)臺根據(jù)需要，有電動和手動兩種驅(qū)動方式，按結(jié)構(gòu)可分為單軸、雙軸和三軸轉(zhuǎn)臺等，具有位置、速率、搖擺、跟蹤等多種功能，用于各種慣性器件、慣性組合、隨動跟蹤裝置等的地面測試。
The inertial navigation test turntable,according to the needs, has two driving modes: electric and manual. According to the structure, it can be divided into single-axis, dual-axis and three-axis turntables. It has multiple functions such as position, rate, swing and track-ing, and is used for ground testing of various inertial devices, inertial units,follow-up tracking devices, etc.
三軸電動轉(zhuǎn)臺是一種能夠?qū)崿F(xiàn)三個(gè)獨(dú)立軸（通常為俯仰、滾轉(zhuǎn)和偏航）旋轉(zhuǎn)的設(shè)備，廣泛應(yīng)用于航空航天、軍事、科研、工業(yè)自動化等領(lǐng)域。
The three-axis electric turntable is a device thatcanrotate onthreeindepen-dent axes (usually pitch, roll and yaw). It is widely used in aerospace, military,scientifc research, industrial automation and other fields.
某兩軸光電轉(zhuǎn)塔設(shè)備需要進(jìn)行線下標(biāo)定測試，需要配置一套三軸測試轉(zhuǎn)臺系統(tǒng)，要求三軸測試轉(zhuǎn)臺的轉(zhuǎn)動范圍和位置精度均要優(yōu)于轉(zhuǎn)塔的運(yùn)動范圍和穩(wěn)定精度。
A two-axis photoelectric tower equipment requires offine calibration testing, and a three-axis test turntable system needs to be confgured. The rotation range and position accuracy of the three-axis test turntable are required to be better than the motion range and stability accuracy of the tower.
由于轉(zhuǎn)塔只有方位和俯仰兩個(gè)自由度，因此對三軸轉(zhuǎn)臺的滾轉(zhuǎn)軸不做精度和動態(tài)指標(biāo)要求，只要求該軸系具有旋轉(zhuǎn)功能即可。
Since the tower has only two degrees of freedom, azimuth and pitch, there are no accuracy and dynamic index require-ments for the roll axis of the three-axis turntable. It is only required that the axis system has a rotation function.
