The utility model relates to an automobile wind tunnel force measurement balance supporting mechanism capable of guaranteeing the accuracy of measurement data, making a mold be placed conveniently, and reducing test cost.
Description
Technical field
The utility model relates to a kind of supporting mechanism, particularly relates to a kind of automobile wind tunnel force balance supporting mechanism.
Background technology
The supporting mechanism of original car model wind tunnel force measurement balance support system is four-wheel positioning supports mechanism, and is as depicted in figs. 1 and 2, among the figure: 1-model pole, 2-days rotating discs, 3-fulcrum bar component, 4-large eccentricity wheel, 5-small eccentricity wheel.The alignment of model pole 1 upper end is also inserted in the pre-drilled pilot hole in car model wheel bottom, and the lower end connects through screw thread and fulcrum bar component 3, the location of implementation model, fixing; Fulcrum bar component 3 connects with wheel, the wheelbase regulating device (not drawing among Fig. 1) of aerodynamic balance measuring system; Wheel, wheelbase regulating device cooperate large eccentricity wheel 4, small eccentricity wheel 5 can make the aerodynamic balance measuring system be fit to the car model of different wheels, wheelbase within the specific limits.During dynamometer check, wind passes to the force cell of aerodynamic balance measuring system to the acting force of car model through model pole 1, fulcrum bar component 3 and wheel, wheelbase regulating device, realizes pneumatic force measurement.
In long-term experimentation, find that the major defect of four-wheel positioning supports mechanism has:
1., wheel is placed on the model pole 1, changed the ground clearance of machine on car and floor, thereby caused the bigger than normal even mistake of measurement data error.
2., when the pre-drilled hole depth in wheel bottom is inconsistent, can cause the alignment error of the car model angle of pitch; When the hole site exists mismachining tolerance big, can cause the model difficult installation even can not install.
3., when cooperating large and small eccentric wheel regulating wheel wheelbase and car model is installed, need more time and experimenter.
4., bore time and the cost that pilot hole has increased modeling in the car model bottom.
The utility model content
The utility model technical matters to be solved provides a kind of accuracy, model of measurement data of guaranteeing and lays conveniently, reduces the automobile wind tunnel force balance supporting mechanism of experimentation cost.
In order to solve the problems of the technologies described above; The automobile wind tunnel force balance supporting mechanism that the utility model provides; Comprise day rotating disc and fulcrum bar component; Be provided with four the T type groove round trays corresponding with wheel at described day on the rotating disc, the bottom of each described T type groove round tray is fixedly connected with described fulcrum bar component, and each described T type groove round tray is provided with the wheel fixture.
The structure of described wheel fixture is that the right angle fixed head is connected with square nut through first sunk screw; Square nut is placed in the T type groove of described T type groove round tray, and described right angle fixed head is provided with the corresponding second fastening sunk screw with wheel.
Be provided with O-ring seal between described T type groove round tray and the described sky rotating disc.
Adopt the automobile wind tunnel force balance supporting mechanism of technique scheme; The small eccentricity wheel and the model pole of former four-wheel positioning supports mechanism have been removed; The large eccentricity wheel is replaced to T type groove round tray; And original fulcrum bar component prolonged with T type groove round tray weld together the new fulcrum bar component of formation, and design new wheel alignment and stationary installation.The vertical plate of right angle fixed head connects with wheel through second sunk screw, and its base plate is drilled with two tapped through holes, and first sunk screw is screwed into the square nut that is installed in advance in the T type groove through tapped through hole, and the right angle fixed head is fixed on the T type groove round tray.In the process of the test, first four wheels with car model is placed on four T type groove round trays respectively and adjusts the position, then the right angle fixed head is close to wheel, is screwed into second sunk screw, and the location of accomplishing the car model wheel is with fixing.During dynamometer check, wind directly passes to the force cell of aerodynamic balance measuring system to the acting force of car model through fulcrum bar component, realizes pneumatic force measurement.Be provided with O-ring seal between T type groove round tray and day rotating disc, can prevent dust and grunge pollution force cell.
Contrast original four-wheel positioning supports mechanism, we can learn that T type groove supporting mechanism has following major advantage:
1. can not change the ground clearance of machine of former car model, guarantee the accuracy of measurement data.
2. eliminated the car model angle of pitch alignment error that produces when using four-wheel positioning supports mechanism.
3. model is laid conveniently, does not need regulating wheel, wheelbase, and is time saving and energy saving, wheel alignment and fixing quick, flexible.
4. save wheel, the wheelbase regulating device of former aerodynamic balance measuring system, need not reduce experimentation cost simultaneously in model wheel bottom hole.
In sum, the utility model is that the automobile wind tunnel force balance supporting mechanism of experimentation cost is laid conveniently, reduced to a kind of accuracy, model of measurement data of guaranteeing.
