Description
Technical Field
The invention relates to the field of automobile suspension structures, in particular to a double-wheel suspension structure control platform based on an electric motor.
Background
In short, the suspension system of the vehicle is the whole support system composed of the spring and the shock absorber between the vehicle body and the tire. The suspension system should function to support the vehicle body and improve the ride, and different suspension arrangements will give the driver a different driving experience. The suspension system which looks like a simple appearance integrates various acting forces, determines the stability, comfort and safety of the car and is one of the key parts of the modern car.
The suspension system is a general term for all force-transmitting connecting devices between a frame and an axle or a wheel of an automobile, and has the functions of transmitting force and torque acting between the wheel and the frame, buffering impact force transmitted to the frame or an automobile body from an uneven road surface and attenuating vibration caused by the impact force so as to ensure that the automobile can run smoothly. Typical suspension system structures are composed of elastic elements, guide mechanisms, shock absorbers and the like, and individual structures are bumper blocks, stabilizer bars and the like. The elastic element is in the form of a steel plate spring, an air spring, a spiral spring, a torsion bar spring and the like, the modern car suspension system mostly adopts the spiral spring and the torsion bar spring, and the air spring is used by individual high-grade cars. Suspension systems are an important component in motor vehicles, which elastically connect the vehicle frame to the wheels, and are responsible for a number of vehicle performance characteristics. Externally, the car suspension system only consists of a plurality of rods, cylinders and springs, but millions of people do not consider the car suspension system to be simple, and the car suspension is a car assembly which is difficult to achieve the perfect requirement because the suspension system meets the requirements of comfort and handling stability of the car, and the two aspects are mutually opposite. For example, in order to obtain good comfort, the shock of the automobile needs to be greatly buffered, so that the spring needs to be designed to be soft, but the soft spring easily causes the automobile to have the unfavorable tendencies of braking, head-up acceleration and severe left and right roll, is not beneficial to the steering of the automobile, and is easy to cause unstable automobile operation.
At present, a mechanical control mode rather than an electric control mode is generally adopted for a buffer spring of an automobile suspension structure, so that the working performance of the automobile suspension structure, such as shock absorption performance, basically depends on the physical characteristics of the buffer spring in the actual driving process, the physical characteristics of the buffer spring cannot be amplified, and the working performance of the automobile suspension structure cannot be naturally improved.

Detailed Description
Embodiments of the electric motor-based two-wheel suspension control platform of the present invention will be described in detail with reference to the accompanying drawings.
An Electric motor (also called a motor or an Electric motor) is an electrical apparatus that converts electrical energy into mechanical energy, and reuses the mechanical energy to generate kinetic energy for driving other devices. The motors are very diverse, but they can be roughly classified into ac motors and dc motors for use in different applications.
The direct current Motor (DC Motor) has the advantages of simple speed control, and the rotating speed can be controlled by only controlling the voltage, but such motors are not suitable for operating in high temperature, flammable environment, etc., and the Motor needs to use carbon brushes as the components (brush Motor) of the current transducer (Commutator), so that the dirt generated by the friction of the carbon brushes needs to be cleaned regularly. Brushless motors are known as brushless motors, and are more power efficient and quieter than those with brushes because they have less friction between the brushes and the shaft. The manufacturing difficulty is higher, and the price is also higher. An alternating current Motor (AC Motor) can operate in high temperature, flammable environment, etc. and does not need to clean up the dirt on the carbon brush regularly, but it is difficult to control the speed because controlling the rotational speed of the AC Motor requires controlling the frequency of the alternating current (or using an induction Motor, reducing the rotational speed of the Motor under the same frequency of the alternating current by increasing the internal resistance), and controlling the voltage only affects the torque of the Motor. The voltage of the common domestic motor is 110V and 220V, and the voltage is 380V or 440V in industrial application.
At present, a mechanical control mode rather than an electric control mode is generally adopted for a buffer spring of an automobile suspension structure, so that the working performance of the automobile suspension structure, such as shock absorption performance, basically depends on the physical characteristics of the buffer spring in the actual driving process, the physical characteristics of the buffer spring cannot be amplified, and the working performance of the automobile suspension structure cannot be naturally improved.

Due to the imperfections of the imaging system, the transmission medium, and the recording device, the digital images are often contaminated by various noises during the formation, transmission, and recording processes thereof. In addition, noise may also be introduced into the resulting image at some point in the image processing when the input image object is not as expected. These noises often appear as an isolated pixel or block of pixels on the image that causes a strong visual effect. In general, the noise signal is not correlated with the object to be studied-it appears in the form of useless information, disturbing the observable information of the image. For digital image signals, the noise table is more or less extreme values, and the extreme values act on the real gray values of image pixels through addition and subtraction to cause bright and dark point interference on the image, so that the image quality is greatly reduced, and the follow-up work of image restoration, segmentation, feature extraction, image identification and the like is influenced. Two basic issues must be considered to construct an effective noise suppression filter: the noise in the target and the background can be effectively removed; meanwhile, the shape, the size and the specific geometric and topological structure characteristics of the image target can be well protected.
