HBM Aids Safety of Fuselage Assembly

January 19, 2011

New three-component force sensors allow aircraft manufacturers to check forces on fuselage sections that use innovative composites.

MARLBORO, MA -- The construction of today's modern commercial aircraft increasingly involves the use of innovative composite materials such as GRP or GLARE (glass-fiber reinforced aluminum). The handling of these materials during assembly sets new challenges for aircraft manufacturers. HBM supports new automated assembly concepts such as these with innovative solutions for process monitoring in order to optimize process safety during production, manufacturing costs and runtimes.

In order to check the forces on the fuselage sections during the assembly process, three-component force sensors were specially developed by HBM. Their signals are acquired by HBM digiCLIP measuring amplifiers and forwarded to the plant control system. The digital measuring amplifiers are characterized by their noise-free and stable measurement technology for reliable measurement results in an industrial environment. The amplifiers are integrated in the automation architecture via the Profibus DP interface. The modules have an internal digital signal processor for calculating process-relevant characteristic quantities of the assembly process, such as instantaneous values, peak values of the press forces and limit value violations. Due to the size and complexity of the assembly line, a large number of measurement channels is often required and can be easily set up by mounting on DIN rails and daisy-chain wiring.

The combination of multi-component TEDS sensors and the modular measuring amplifier system digiCLIP means that HBM offers a complete measurement technology solution. This solution sets new standards in terms of economic efficiency and effectiveness, both during installation and on-going operation, so that the new materials, despite their increased complexity, can be cost-optimized and safely used during serial production.
