Description
Technical field
The invention belongs to High-sped Trains fields of measurement, particularly to a kind of high-speed rain movable model type six component aerodynamic force
Measurement apparatus.
Background technology
At present, with the raising of train speed, shared by aerodynamic drag, the ratio of drag overall is increasing, when speed is more than
During 300km/h, this ratio can exceed 85%, and aerodynamic force is one of most important environmental load of bullet train.The model of train at present
Experiment mainly adopts wind tunnel experiment and movable model experiment, and movable model experiment not only can simulate the relative motion of train and air,
Train and ground, tunnel, other trains can also be simulated the relative motion stream field of works and the impact of aerodynamic force such as cross,
Its experiential function is substantially better than wind tunnel experiment.But existing movable model experimental technique is confined to discrete point Pneumatic pressure both at home and abroad
Measurement, still can not measure pneumatic (total) power, this respect is not as good as wind tunnel experiment.Due to aerodynamic force, (particularly aerodynamic drag is divided
Amount) it is most important design parameter in engineering, the measurement of aerodynamic force becomes a technical bottleneck of movable model experiment, and it is serious
Constrain its function performance it would be highly desirable to break through.
Form main reason is that of above-mentioned technical barrier：One is because assay device total length is limited and is divided into acceleration
Section, measuring section, braking section, model needs to reach experiment setting speed by accelerating sections at short notice, and acceleration is up to tens
Individual g；And in measuring section, deceleration less (about 0.5g), close at the uniform velocity advancing, aerodynamic force phase is much smaller than the used of accelerating sections to model
, there is the difference of the order of magnitude in property power；After entering into braking section, model need to be braked again at short notice, and deceleration is big with acceleration
Little quite.If also installing force balance between supporting mechanism and car mould as wind tunnel experiment, its range certainly will be required necessary
Sufficiently large, this may lead to the aerodynamic force of measuring section to be submerged in its noise, thus causing transducer range and certainty of measurement
Between contradiction；Two is that the irregularity of slide rail can cause certain the jolting of car mould, and the measurement to aerodynamic force interferes；Three are
State measurement requirement dynamic compensation (multi -components)；Four is that car mould should have high intensity/mass ratio, to resist huge inertia force simultaneously
Obtain big scale model.Solve above-mentioned technical bottleneck it is critical only that force cell plus/unloading two-way overload protective and
It is transitioned into rapidly measuring section, but there is no the multi -components force cell of this built-in overload protecting mechanism at present both at home and abroad.
