Abstract
A method for measuring ice load attached on ocean platform includes setting force measuring balance on platform legs near to sea surface, leading signal measured by said balance to recorder, processing signal in recorder to obtain dynamic time-histories of ice load formed on platform .In the method, eight sextet-component force transducers set on jacket tubes in two layers uniformly are applied to measure ice load attached on legs of platform in omni bearing way.
Description
Technical field
The present invention relates to a kind of ice load measuring method of sea platform.
Background technology
In the northern marine site of China such as the Bohai Sea, ocean platform can be subjected to the effect of glacial ice, and this effect can cause the platform vibration.In the frequency spectrum of this effect, comprise or can cause the autovibration of platform during natural vibration period, accelerate the fatigue failure of platform and influence normal life and the work of personnel on the platform near platform structure.The feature that the therefore correct suffered ice of Evaluation Platform carries is the key factor in the platform design.Ice carries and measures the load cell devices that adopt more at present, is used for the ice power of being born on the certain area of measuring table.Because load cell has boundary effect, can not directly measure leg post shortcoming such as ice power always, also has certain problem in actual applications, therefore how can measure ice more convenient, efficiently and accurately to carry, be one problem to be solved to be arranged.
Summary of the invention
At the problem that existing measurement mechanism exists, the object of the present invention is to provide a kind of can the measurement effectively, easily and accurately to ice the ice load measuring method of sea platform that carries.
For achieving the above object, the technical scheme that the present invention proposes is:
A kind of ice load measuring method of sea platform, near near the sea force balance is being set on the platform leg post of described ocean platform, this force balance is by lead linkage record instrument, the signal of force balance output is introduced registering instrument by lead, and the signal in the registering instrument is promptly obtained the moving time-histories that the suffered ice of platform carries through handling.
Further, the platform leg post of described ocean platform at the cylindrical casing of this cylinder arranged outside one diameter greater than described platform leg post, is provided with at least one force transducer near being cylinder near the sea between this cylindrical casing and described platform leg post.
Further, the platform leg post of described ocean platform is provided with ice breaking cone near near the outside sea, is provided with at least one force transducer between this ice breaking cone and the described platform leg post.
Further, be provided with eight force transducers between described cylindrical casing and described platform leg post, these eight force transducers divide two-layer being distributed on the described cylindrical casing.
Further, be provided with eight force transducers between described ice breaking cone and described platform leg post, these eight force transducers divide two-layer being distributed on the described ice breaking cone.
Further, described force transducer is a six-component force sensor.
After adopting said method, owing near near the sea force balance is being set on the platform leg post of described ocean platform, this force balance promptly obtains moving time-histories that platform suffered ice carry with the signal in the registering instrument through handling by lead linkage record instrument.Can note in real time the moving time-histories of the suffered ice load of ocean platform by said method, for the optimal design and the improvement of ocean platform provides basic data.In addition, owing to select eight six-component force sensors in the present invention, these eight six-component force sensors divide two-layer being distributed on the cylindrical casing, therefore can comprehensively record the suffered ice of platform leg post and carry; And the employing six-component force sensor does not change the original structure of ocean platform, and is easy to use.
