Description
Technical field:
The utility model relates to flight load flight test, particularly aircraft vertical fin load calibration test.
Background technology:
When utilizing strain gauge method to carry out flight load measurement, ground calibration test must be carried out to the aircraft mainpiston (wing, vertical fin, horizontal tail) completing strainometer repacking.The common method of calibration test on plane airfoil, chooses beam and rib intersection point as load(ing) point, then utilizes lifting jack, hydraulic actuator, loading backing plate etc. directly to load aerofoil, obtains load equation.But when vertical fin load calibration test in the past, need to manufacture portal frame equivalent-load device, pressurized strut is installed with mobile more difficult, and it is lean on manpower to realize that pressurized strut loads that center accurately aims at load(ing) point, wastes time and energy and error is larger.Especially when loading aerofoil is distant from actuator, accurately more difficult to point.
Summary of the invention:
The object of the invention manufactures and designs the stepless motorized adjustment of a kind of vertical fin to load stand, directly actuator will be loaded or lifting jack is mounted thereto, utilize motor and leading screw to realize loading actuator to coordinate with the stepless of load(ing) point, guarantee vertical fin calibration test loading accuracy; And many actuator can be realized to greatest extent simultaneously to point, the function that load applies simultaneously.
The utility model is realized by following technical proposal:
The electrodeless motorized adjustment of a kind of vertical fin loads stand, it is characterized in that, comprise heavy frame, course trave lling girder, normal direction mobile platform, course motor, normal direction motor, the workplace of heavy frame is parallel with the two dimensional surface at vertical fin load(ing) point place, course trave lling girder is installed on the workplace of heavy frame, driven by course motor and move along vector, normal direction mobile platform is installed on the trave lling girder of course, is driven move along aircraft normal direction by normal direction motor.By this feature, the normal direction mobile platform realized residing for charger in the region-wide movement of load(ing) point two dimensional surface, thus can meet all standing of charger for load(ing) point.
Further, course trave lling girder has more than 2, and normal direction mobile platform 3 has more than 2, realizes the loading of more than 2 load(ing) points simultaneously.By this feature, the normal direction mobile platform residing for charger realizing more than 2 can in the region-wide movement of load(ing) point two dimensional surface, thus meets more than 2 load(ing) points and load simultaneously.
" the electrodeless motorized adjustment of vertical fin load stand " be for meet load according to flight test vehicle vertical fin and design a kind of can the load maintainer of electrodeless adjustment, main heavy frame, course trave lling girder, normal direction mobile platform, course motor, normal direction motor, this loading stand can realize more than 2 load(ing) points simultaneously and load; Because will fix after adjusting to assigned address, so travel mechanism must can self-locking, determine gear train-worm speed reducer and the transmission of square tooth lead screw nut with self-locking property thus.Estimate required drive size according to concrete structure, select each several part of motor and gear train; Loading Position adjustment adopts motor to drive and hand drive two kinds of modes, so that very trickle adjustment.Travel mechanism adopts rolling transmission, utilizes roller (single or double) to make planker and pressurized strut support-moving, friction force when can reduce mobile as far as possible like this, and avoids producing jam phenomenon.Carry out circuit design, adopt position control and mobile manual two kinds of modes.Adopt building block design thinking, a complete set of equipment can be resolved into three parts, can dismantle very easily and install.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of positive apparent direction of the present utility model.
Fig. 2 is the schematic diagram in side-looking direction of the present utility model.
Embodiment
Following accompanying drawings 1 and 2 pairs of the utility model further illustrate:
The electrodeless motorized adjustment of a kind of vertical fin loads stand, it is characterized in that, comprise heavy frame 1, course trave lling girder 2, normal direction mobile platform 3, course motor 4, normal direction motor 5, the workplace of heavy frame is parallel with the two dimensional surface at vertical fin load(ing) point place, course trave lling girder is installed on the workplace of heavy frame, driven by course motor and move along vector, normal direction mobile platform is installed on the trave lling girder of course, is driven move along aircraft normal direction by normal direction motor.By this feature, the normal direction mobile platform realized residing for charger in the region-wide movement of load(ing) point two dimensional surface, thus can meet all standing of charger for load(ing) point.
The electrodeless motorized adjustment of vertical fin of the present utility model loads stand, and it is characterized in that, course trave lling girder 2 has more than 2, and normal direction mobile platform 3 has more than 2, realizes the loading of more than 2 load(ing) points simultaneously.By this feature, the normal direction mobile platform residing for charger realizing more than 2 can in the region-wide movement of load(ing) point two dimensional surface, thus meets more than 2 load(ing) points and load simultaneously.
" the stepless motorized adjustment of vertical fin loads stand " is mainly used in the calibration test of aircraft vertical fin.During installation, can first loading actuator be fixed in loaded seat, motor is adopted to drive and hand drive two kinds of modes, so that very trickle adjustment, actuator is accurately aimed at load(ing) point, after actuator puts in place, realize transmission and self-locking by the gear train-worm speed reducer and the transmission of square tooth lead screw nut with self-locking property.
It is as follows that the stepless motorized adjustment of vertical fin loads stand technical indicator:
1) load-bearing capacity:
7060mm place side load can reach 50KN
2) overall weight≤4.5t;
3) actual mobile height 3120mm≤H≤7060mm;
4) safety coefficient 3.0
With " the stepless motorized adjustment of vertical fin loads stand ", aircraft vertical fin is loaded, mainly has the following advantages and good effect:
1) electronic stepless to a function, avoid a large amount of manpower and materials, lightly can realize vertical fin calibration test and load demand;
2) wider two-dimensional adjustment ranges, can realize different types of machines vertical fin and load;
3) can meet vertical fin multi-point combination value-added tax function, this function is that domestic realization of the same type is initiated; This equipment only has for domestic at present.
