The frame is also called a beam. The basic body of a car, generally consisting of two longitudinal beams and several beams, is supported on the wheels via suspension devices, front and rear axles. Has enough strength and stiffness to withstand the load of the car and the impact from the wheel.
To evaluate the quality of the frame design and structure, first of all, it should be clearly understood that the various forces that the frame is subjected to when the vehicle is traveling. If the stiffness of the frame is not good in some respects, no matter how good the suspension system is, it will not achieve good control performance. The frame has to face four kinds of pressure in the actual environment.
Girder and load-bearing frames are the predominant forms of mainstream frames, but they all have significant drawbacks, namely, they are bulky and have insufficient rigidity. Therefore, in recent years, the advantages and frame design of the fusion of the two have emerged. The original frame of Mitsubishi PAJEROIO has added an independent steel frame at the bottom of the load-bearing structure, which can be considered as a simplified girder structure, so as to ensure the rigidity at the same time The weight and center of gravity are much lower than those of the beam structure. Another example is the Honda S2000. Due to the high performance requirements and the lack of rigidity of the open-air body, a stiffening structure resembling a large cross-beam was welded to the bottom of the load-bearing frame, thereby increasing rigidity. In the future, the form of this "hybrid" frame will surely emerge in an endless stream.
The frame is mainly composed of longitudinal beams, cross beams, engine brackets, clutch brackets and other accessories. The frame is divided into welded frames, riveted frames, and riveted/welded frames according to different processes. Medium and heavy trucks mainly use riveted frames.
The frame structure can be divided into non-bearing type, semi-bearing type and carrying type according to the force conditions.
Vehicles with a non-loaded body have a rigid frame, also known as a chassis frame. The frame-to-body connection is flexibly connected via a spring or rubber mat. Parts of the engine, the drive train, body parts, etc. are fixed to the frame by a suspension device, and the frame is connected to the wheels through front and rear suspension devices. This type of non-loaded body is relatively bulky, of high quality and high in height. It is generally used on trucks, passenger cars and off-road jeep cars, and it is also used in a small number of high-class cars because of its good stability and safety.
Vehicles with a load-carrying body do not have a rigid frame, but only the front, side, rear, and floor parts of the vehicle are reinforced. Parts of the engine, front and rear suspension, and a part of the drive train are assembled on the vehicle body at the required design position. Pass the suspension to the wheels. In addition to its inherent load-carrying function, this type of load-bearing vehicle body is also directly subjected to various load forces. After decades of development and improvement, the load-bearing vehicle body has greatly improved both in terms of safety and stability, and has advantages such as low quality, low height, no suspension device, and easy assembly, so most of the cars are This body structure is used.
The body and frame are rigidly connected by screws, rivets, or welding. In this case, in addition to the above-mentioned loads, the automobile body still contributes to the reinforcement of the frame to some extent, sharing part of the load of the frame.

Matting Agent For Advertising Film
A Matting Agent in the context of an advertising film is typically used to enhance the visual quality of the footage, often for post-production purposes. There are several types of matting agents that can be utilized depending on the specific needs of your project:
1. Green Screen/Blue Screen Matting: This technique involves shooting a scene with a green or blue background (the key color). After filming, this color is removed in post-production, allowing you to replace it with any background of your choice. This is commonly used in VFX and special effects.
2. Color Correcting Filters: These are often used during the filming process to adjust the color balance of the footage. This helps in creating a consistent look across different shots, making the final edit smoother.
3. Digital Effects (DVs): Software tools like Adobe After Effects or Final Cut Pro can be used to add digital elements to your film, such as animations, overlays, text, or to manipulate scenes.
4. Matte Painting: This is a traditional art form where artists paint detailed images onto a blank canvas to simulate environments that don't exist in real life but can be seamlessly integrated into the film. This can include landscapes, futuristic settings, or fantastical scenes.
5. Rotoscoping: This technique involves tracing over live-action footage frame by frame to create animation or to isolate specific movements for further editing or effects application.
6. Keying Techniques: Apart from simple green screen/blue screen, there are more complex keying techniques like Luma Key, Chroma Key, and Color Difference Key which can help in removing backgrounds or isolating subjects for better integration into new scenes.
7. Comp Effects: In a broader sense, compositing (or comp) effects refer to the process of combining multiple layers of footage, graphics, or animations into one seamless scene.
The choice of a 'matting agent' depends largely on the specific requirements of the film, the desired outcome, and the resources available. It's crucial to consider the time, budget, and expertise required for each technique to ensure the best possible result.
