The application provides an output torque calculation method of a driving device, the driving device is used for driving a supporting structure of a driving part, and the method comprises the following steps:
step one, judging whether the total driving capability of the driving device meets the requirement, and if so, entering a step two;
secondly, acquiring the load of each supporting structure of the driving part under the support of the mechanical structure, and acquiring the driving capability of each driving unit of the driving device, wherein the driving units correspond to the supporting structures one by one;
step three, judging whether the driving capability of each driving unit of the driving device is larger than the load of the corresponding supporting structure,
if yes, determining the output torque of the corresponding driving unit according to the load of each supporting structure;
if not, the output torque of each driving unit of the driving device is matched again.
According to the method for calculating the output torque of the driving device, the driving device is generally in a distributed lug structure operated by electricity and hydraulic pressure, the driving of a front edge control surface and a weapon cabin door can be realized, and the driving device has the advantage that the weight of a supporting structure of the driving device can be reduced. The driving component comprises a front edge control surface and a weapon cabin door, the supporting structure can be a supporting rocker arm, and the supporting structure supports the driving component in a mechanical structure supporting mode.
According to the output torque calculation method of the driving device, the torque of the serious load on the rotating shaft of the driving part is calculated according to the serious load state of the driving part, and compared with the driving capability of the driving device, whether the driving capability of the novel driving device meets the requirement or not is determined. Specifically, in the step one, determining whether the total driving capability of the driving device meets the requirement includes:
s101, acquiring the maximum output torque of a driving device;
s102, acquiring the moment of a rotating shaft of the driving part when a load is applied to the driving part;
s103, judging whether the maximum output torque of the driving device is larger than the torque of the rotating shaft of the driving part or not, if so, enabling the total driving capability of the driving device to meet the requirement, and if not, enabling the total driving capability of the driving device not to meet the requirement.
In S102, acquiring the torque of the rotating shaft of the driving member when the load is applied to the driving member includes:
constructing a finite element model of the driving part;
applying the distributed pneumatic load to a finite element model of the driving part, and acquiring the total load born by the driving part and the pressure center position;
and calculating the moment of the rotating shaft of the driving part according to the total load and the position of the pressure center.
In this embodiment, the total load multiplied by the distance from the pressure to the shaft is the torque of the shaft of the drive member.
In the third step, the step of re-matching the output torque of each drive unit of the drive device comprises:
according to the output torque calculation method of the driving device, the output torque of the driving unit with the driving capacity not larger than the load of the corresponding supporting structure is compensated by increasing the output torque of other driving units.
In one embodiment of the present application, the total driving capability of the novel driving device, i.e. the maximum output torque, is 110KN · m, the torque of the serious load of a certain driving component to the rotating shaft of the driving component is calculated to be 100KN · m, and the total driving capability of the driving device is greater than the torque of the serious load of a certain driving component to the rotating shaft of the driving component, so that the total driving capability of the novel driving device meets the requirement. In this embodiment, a certain driving member is supported by 4 supporting rocker arms, the novel driving device includes 4 driving units, and each supporting rocker arm is connected with a corresponding driving unit. Assuming that the supporting rocker arm is in pure mechanical connection with the novel driving device, simulating the rigidity of the supporting rocker arm and applying constraint conditions in a finite element model according to a traditional multi-degree static and uncertain calculation method, and extracting the load of the supporting rocker arm to obtain the load of each supporting rocker arm as follows: 40KN · m, 30KN · m, 20KN · m, 10KN · m. The driving capability of the four driving units of the novel driving device is respectively as follows: 40KN · m, 20KN · m, 30KN · m, 20KN · m. By comparing with the rocker arm supporting load, the driving capability of the driving units of the 1 st, 3 rd and 4 th driving devices is satisfied, but the driving capability of the 2 nd driving unit is insufficient. The output torque of each drive unit of the drive device needs to be re-matched, the 2 nd drive unit needs to bear the load of 30KN · m, and the maximum drive capacity is 20KN · m, so the rest 10KN · m load is borne by the 3 rd drive unit, and the 3 rd drive unit finally bears the load of 30KN · m, and the drive capacity of the 3 rd drive unit is 30KN · m, which just meets the requirement. Finally, the output torques of the 4 drive units of the novel drive can be based on, i.e. the final loads to which each drive unit is subjected are: 40KN · m, 20KN · m, 30KN · m, 10KN · m. Therefore, the omnibearing, multidimensional and refined strength design load is realized.
According to the output torque calculation method of the driving device, the intensity design load calculation can be refined, the structural load is supported through all-dimensional multi-dimensional calculation, and the risk that the structure does not meet the intensity design requirement is reduced.
The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application.
