无接触激光测量技术在橡胶工业中的应用
Tread measurement
The entire contour of a tread can be measured by two traversing laser sensors (above and below the material). The measurements are possible for both car and lorry treads. The measured profile is compared to a master profile stored in the computer and monitored with respect to given tolerances. Logging and graphic display of the tread is possible. Measuring systems for offline and online measurement are available.
胎纹测量
整个胎纹的轮廓可由两个分别安装于被测产品的上方和下方的激光传感器进行测量。这种测量对骄车和卡车胎纹均适用。所测量胎纹轮廓与储存在计算机中的标准纹型进行比较，按给定公差进行监控，并以数据和图形的形式进行显示，在线或线下测量系统均可实现。
Profile measurement
It is possible to measure profile surfaces by combining an OPTIMESS laser sensor with a drive unit, e.g. linear unit or robot. This may be profiles of tire surfaces and technical products of the rubber industry such as the profile of single or multiple V-belts or toothed belts. The possibility of adapting the laser point diameter individually to sensors in OPTIMESS as well as the ability to measure on inclined surfaces up to about 80° open up new possibilities for online quality inspection.
外形测量
将一个OPITMESS激光传感器与一个驱动装置（如线性运行装置或机器人）联接，可以测量外形轮廓表面。外形可以是轮胎表面或者橡胶工业的技术产品，比如单层或多层V-形带、齿形带等。激光点直径可根据OPTIMESS传感器进行单独调整，表面测量倾角甚至可以接近80°，为在线质量监测开辟新的应用。
Thickness measurement
Two sensor layouts are available basically for the thickness measurement. One sensor is used for the reference measurement on a roller. The product runs over a roller which is used as a basis for the zero point. The subsequent measurement on the product is set off against the zero point and output as a thickness. In the thickness measurement with two sensors the product runs between two sensors, one above, one below the material. The difference between the two sensor values gives the thickness. The advantage of this measuring set-up is that the product can move vertically to the direction of travel without causing measuring errors. Air-cooled OPTIMESS sensors are available for measuring warm materials. Traversing thickness measuring systems are available in addition to the stationary thickness measurement with separate measuring tracks.
厚度测量
布置两个传感器是进行厚度测量的基础。首先为一个滚筒指定原点，产品在滚筒上移动，与转轴接触的一面被作为零点，接下来的测量是相对于零点测出一个厚度值。另一种厚度测量，产品在位于其上方和下方的两个传感器之间移动，两个传感器测出的距离差得出产品的厚度值，这种测量装置的优点是产品可以在传送时上下振动时不会发生测量误差。空气冷却的OPTIMESS传感器可以对高温材料进行测量。穿梭厚度测量系统可以实现不同轨道的固定厚度测量。
Width measurement
Two OPTILINE systems are used respectively for the width measurement. The width is measured by the shadow measurement method which means that the laser generates a parallel band of light which is projected onto a detector. The continuous rubber band shades part of the laser beam from the detector. The position of this shadow is evaluated and output as a width by calculating the difference of both systems. No additional light source Is required for the measurements.
宽度测量
两个OPTILINE系统被很好的用于宽度测量。宽度测量采用影子测量法，操作原理是激光将一束平行光束投射到一个接收器上，而连续运动的橡胶带会遮档部分光束，评测投影的位置，计算两个系统的差异而输出宽度，测量中不需要附属光源。
Overlap measurement
It is very important for the manufacturing of tires whether two layers of rubber overlap, touch or form a gap. OPTIMESS sensors are suitable for quick detection of measured value jumps or overlaps due to their high measuring frequency of up to 50 kHz. Edge Jumps can therefore be detected with a high reproducibility in connection with a distance measuring system.
重叠测量
对于轮胎制造业，测量两层橡胶的重叠、接触、或者存在间隙，都非常重要。OPTI MESS传感器可快速检测以上指标，测量频率高达50KHz。因此，与一个距离测量系统连接,可以快速再现边跳状况。
Expansion measurement
The non-contact scanning of the tire surface enables measurement of the expansion of a tire at maximum speeds. This can be done both on the test stand and directly on the vehicle.
膨胀测量
无接触轮胎表面扫描可测量轮胎在高速下的膨账量，它既可用于标准测试也可直接用于车辆检测。
Non-concentricity measurement
It is possible to measure the vibration and wobble up to maximum speeds using the special OPTILINE system. Here too up to 20,000 measurements/s are possible. Special OPTIMESS laser sensors are being used in test machines made by Seichter as an alternative to capacitive measurement for non-concentricity and dents.
偏心率测量
运用特殊的OPTILINE系统测量轮胎在最高速度下的摆动性及振动性，可达到20000次/秒的测量速度。特殊OPTI MESS激光传感器被用于由SEICHTER公司制造的机器中，代替电容测试，用于偏心率测量。
Deformation measurement
OPTIMESS sensors allow non-contact measurement of tire deformations under different test conditions such as wheel load, track and king pin angle. These may be measurements on the roller test stand but also measurements on the test vehicle - due to the small size of the sensors. An extreme application here is the deformation measurement inside a lorry tire. A special OPTIMESS sensor is mounted on the rim inside the tire and measures the contact surface of the tire.
变形测试
OPTI MESS传感器可实现在不同测试条件下形变测试，比如车轮承载，轨迹和景斌倾角(汽车转向几何学角度)等，它既可在滚筒架上测量也可在车辆检测中使用——由于传感器体积小，它还可以在卡车轮胎内中测量形变。特型OPTIMESS传感器被装于轮胎内侧轮沿上用于测量轮胎的接触面。
Test drive/Texture measurement
The laser is a virtually unrivalled measuring instrument for the non-contact measurement of the distance between vehicle and road to characterize the road handling. In the field of tire test drives the laser offers the possibility of scanning the tire surface on a test machine, i.e. the whole tire surface is measured according to specified drive cycles to examine and document saw tooth formation, erosion, etc. in addition to normal wear. The laser offers other application possibilities In the deformation measurement of the tire when the vehicle is in motion and the measurement of road surfaces as an important parameter in the development of tires with respect to aquaplaning and noise behavior.
试驾/材质测量
实际在车辆与道路的间距、道路路况的无接触测量，激光则独占鳌头。在轮胎测试驾驶中，测试机用激光扫描轮胎表面：包括在特定行驶周期内检测记录锯齿形变，侵蚀等，加上正常的磨损等全部轮胎表面数据。激光技术测量轮胎在车辆运动过程中的形变，路况，也为轮胎打滑及噪声研究提供重要参数。
