飞机一旦装配完，就必须测量飞机的重心. 目前是使用机械系统进行测量. 但是其测量精度不高，不能满足需要. 因此需要更好的技术来进行测量，达到更高的测量精度.
The general problems here are the very flexible structure of an aircraft and the fact that lateral forces greater than 10% can occur in the longitudinal and transverse axes. A further complicating factor is that there is very little space available for the measuring instrument.
In highly detailed comparison tests under real conditions the HBM series C4 force transducer put in a convincing performance despite the difficult framework conditions. Linearity and reproducibility in different installation positions were of particular interest. The C4 was able to far exceed expectations in all respects.
Nonetheless, preliminary tests gave rise to the wish to optimise the results still further with recognition of the lateral forces in the x and y axes. HBM is able to draw on decades of know-how in the construction of force transducers and other equipment, and utilises this knowledge for standard transducers and in particular for customer-specific transducers – some of which for extreme requirements. In this case the requirement could be met by customising the standard transducer specifically for the customer with double bridges and external x and y channels.
The measurement equipment is rounded off with what is still the most accurate measuring system for starin gage transducers, the DMP40. This system provides measurement signal resolutions up to the limit of the component noise.
The follow-up tests were all very successful, such that further measurement systems are being realised for this application. The solution found using HBM’s measurement technology puts in a persuasive performance by combining clever technology with simplicity of use. These advantages – coupled with precision and reliability – certainly pay off, as evidenced by a cost comparison: the new solution costs much less. It also forms a good reference solution from HBM for the worldwide use of such systems.
