Definitions
- the invention relates to the technical field of mechanical engineering and mathematics research, and particularly relates to an asymmetric variable acceleration motion planning method based on optimal time domain distribution of main frequency energy.
- a mechanism device with a motion acceleration of more than 10 g is considered to be a "soft body", and its dynamic characteristics are largely different from those of a general rigid body mechanism.
- the above-mentioned high-acceleration actuator has a large inertial energy effect, and the residual vibration is high under high acceleration conditions such as high-speed start-stop, which requires a long decay time of the mechanism elastic vibration energy to meet the requirements of high-precision positioning.
- the common solution is to design a smooth acceleration motion planning curve to reduce the vibration shock caused by acceleration changes in high-speed motion. For example, the common S-curve plan for manufacturing.
- the traditional solution is mainly to plan the motion from the geometric smoothing of the motion acceleration curve. Because it does not optimize the motion planning of the actuator from the perspective of the inherent physical reasons such as the stiffness, inertia, and natural frequency of the mechanism, the obtained motion curve may generate harmonics during the driving process. Therefore, some researchers have proposed to use filtering. Eliminate the resonance component. However, there are still two problems in this method: 1) the natural frequency of the mechanism changes with the shape of the motion, and it is necessary to design a filter with variable band resistance; 2) the motion is not in place after filtering, further motion compensation is needed, and the efficiency is reduced.
- patent 201310460878.9 proposes an S-shaped motion curve planning method to reduce residual vibration through flexible multi-body dynamics simulation optimization, and converts the S-curve parameters from geometric design to dynamic design, which improves the adaptability.
- Patent 201310460878.9 proposes a S-shaped motion curve planning method for high-speed mechanism to reduce residual vibration.
- the method mainly considers the influence of mechanism flexible vibration attenuation on positioning time, and increases the decay time based on the traditional S-type motion planning method.
- the S-curve planning model considering the influence of the residual vibration of the high-speed mechanism with the shortest positioning time is established, which can better ensure the motion stability of the high-speed mechanism and reduce the positioning time of the high-speed mechanism.
- a high-precision censored dynamic substructure method is used to create a flexible multi-body dynamics model of the actuator, and the flexible multi-body dynamics model remains unchanged in the subsequent motion parameter adjustment optimization process.

Precision positioning under conditions and smooth switching of bits/forces.

- T 1 G 1 (T 1 +T 2 ) T 3 G 3 (T 3 +T 4 )
- T 2 , T 3 , and T 4 can all be represented by T 1 .
- the decay time T 5 is judged by:
- the velocity v is larger than the displacement number s.
- the velocity v is almost zero, that is, when the mechanism position s falls within the positioning accuracy ⁇ , the above formula is established.
- the optimization model described in step 5 is:
- T T 1 +T 2 +T 3 +T 4 +T 5
- T 1 G 1 (T 1 +T 2 ) T 3 G 3 (T 3 +T 4 )
- the invention aims to meet the shortest positioning time under the positioning accuracy by the above method, and proposes an asymmetric variable acceleration planning method with optimal inertia energy time distribution: including nonlinearity including kinematic freedom and parameterized motion function as boundary conditions.
- the finite element model is located to solve the problem; determine whether the amplitude of the actuator after the stop is satisfied meets the positioning accuracy, if not, continue to solve, if it is satisfied, the vibration energy decay time; determine the target response time (the sum of the drive time and the vibration energy decay time) Whether it is the minimum value, if it is the minimum value, it is determined that the set motion parameter is the optimal parameter. If it is not the minimum value, the motion parameter gradient and the step size are calculated, and the motion parameter is reset to solve the problem.
