LamaLo科技股份有限公司（LLT）常常进行船舶推进系统振动测量和动力测量，以支持新产品研发、推进系统升级和故障排除。Binsfeld TorqueTrak 10K遥测系统用来测量轴的扭矩。测量过程在手提电脑上可以实时显示，并对设备的振动严重程度进行评估，现场发送轴功率数据。
LamaLo Technology Inc. (LLT) commonly conducts marine propulsion shafting vibration and powering measurements in support of new construction, propulsion upgrades, and troubleshooting. Binsfeld TorqueTrak 10k telemetry systems are used to measure the shaft torque. Measurements are displayed in near-real time on the lap top computer, so an assessment of the vibration severity and delivered shaft power on-site.

      最近刚刚进行完一个船舶项目，该船建于1969年。推进系统有两个固定螺距螺旋桨，各有一台柴油发动机来驱动。该船舶从施工开始就在进行各种改装整修，包括在1976年和1980年分别增加了安定翼和新的柴油发动机。在2010/2011年间，该船进行了改装，包括轴系、螺旋桨和的船艏推进器的升级。该船的行驶速度比改进前有了比较大的提升。
A recent project involved a vessel that was built in 1969. The propulsion system had two xed pitch propellers, each driven by a diesel engine. The vessel had gone under various rets since construction, including adding sponson tanks in 1976 and new diesel engines in 1980. In 2010/2011, the vessel had a ret conducted, which included upgrades to the shafting and propeller, and the addition of a bulbous bow and a bow thruster. The vessel service speed was 11.5 knots prior to the upgrade.

      这个项目的主要目标是测量并报告在海上试航过程中动力性能和轴系扭振特性。测量的结果表明，12.9 海里/小时的速度时，轴转速约296 RPM，功率为928马力。使用新的螺旋桨，在同样的轴速度下，动力可以提升15%以上。轴转速较低时扭振较大，导致齿轮咬阂问题出现。因此根据扭转振动测量结果将最小轴的速度设置到60 RPM。图1和图2显示的是测量结果。
The primary objective of this project was to measure and report on the powering performance and shafting torsional vibration characteristics during sea trials. The results of the measurements indicated that a speed of 12.9 knots was achieved with a total shaft power of 928 HP at a shaft speed of about 296 RPM. About 15% more power was developed with the new propeller at the same shaft speed. Excessive torsional vibrations were measured at low shaft speeds, resulting in gear tooth backlash. The minimum shaft speed was set to 60 RPM based upon the torsional vibration measurements. Figures 1 and 2 illustrate results of the measurements.

      对于这次的船舶推进系统, TorqueTrak 10K 遥测仪器是用来验证和证明最近的系统升级带来的益处，即以更低的动力和更少燃料的使用，提高了船的速度。这正是设计师所希望看到的。同时，TorqueTrak10K被用来检查扭振，给矫正方法的提出提供指导依据。
For this marine propulsion system, the TorqueTrak 10K telemetry instrument was used to verify and demonstrate the associated benets of a recent system upgrade, namely, an increase in vessel speed at less power and less fuel usage. That is exactly what the designers had hoped to see. At the same time, the TorqueTrak 10K was used to check torsional vibration in order to put corrective measures in place.
