The frame has to pass-how important is the frame to a motorcycle?
Author:
The frame is equivalent to the skeleton of a motorcycle. It is a key component that connects and carries the engine and transmission system, suspension braking system, walking system, auxiliary equipment, and drivers and passengers of a motorcycle. The longitudinal inertial force during acceleration and braking, as well as the impact of the road surface and the deformation when driving in a curve.
There are about a dozen common motorcycle frames, from diamond-shaped jumper frames, T-shaped integrated frames, single cradle frames, etc., which are commonly used in low-end models, to woven steel tube frames, diamond frames, aluminum alloy double-wing beam frames, to extremely luxurious carbon fiber integrated frames, etc.
Regardless of the form of the frame, it must be able to meet the following requirements.
First, to withstand the longitudinal inertia caused by braking and acceleration when the motorcycle is driving in a straight line, and to resist the lateral torsion deformation when driving in a curve, a certain degree of rigidity is required.
Second, resist the impact from engine vibration and avoid resonance with the vibration frequency of the engine, otherwise the overall strength and reliability of the frame will continue to decrease, resulting in poor comfort and increased engine noise and jitter.
Third, to resist the accumulation of dynamic stress caused by uneven road surfaces, poorly designed frames are often prone to metal fatigue after not being used for a long time, which in turn causes the frame to be welded and deswelded.
Fourth, as much as possible lightweight design, reduce the dead weight of the vehicle, improve the driving texture.
Fifth, good acid and alkali resistance, corrosion resistance, oxidation and corrosion resistance, involving the frame surface treatment process is up to standard.
However, due to the influence of cost factors, not every motorcycle frame can be perfect in the above aspects.
The frame used on large-displacement high-performance motorcycles is more urgent for the pursuit of frame performance.
As one of the key components on a motorcycle, the design and manufacture of the frame is a very professional field. The dazzling variety of professional equipment can make you amazed, such as various CNC milling machines, grinders, lathes, presses, Thread rolling machines, friction presses, welding and cutting equipment, heat treatment equipment, various fixtures, metal surface treatment and spraying equipment.

A brief analysis of the structural characteristics of motorcycle frames and their maintenance
As a part of the motorcycle assembly, the motorcycle frame bears a variety of complex loads. The strength, stiffness and inherent characteristics of its structure are important design indicators of the frame. Most motorcycle frames adopt complex tube and plate welding structures, which are the supporting framework of the motorcycle. In the whole vehicle, it must not only meet the requirements of many body parts installation, but also ensure the smooth running of the vehicle, therefore, the structural size and shape accuracy of the frame are required to be high. Motorcycle frame is often deformed after welding, which not only directly affects the assembly and performance of the whole vehicle, but also may reduce the carrying capacity of the frame structure and cause accidents. Therefore, it is very important to limit and eliminate welding deformation in manufacturing. It is of great practical value to carry out the optimization design of motorcycle frame structure and improve its performance.

What is the role of the motorcycle frame?
The frame is the skeleton of a motorcycle. It organically connects the engine, transmission system, suspension, steering, wheels, etc. to form a whole. It not only bears the weight of the engine and other components, but also receives impact and vibration during driving. Therefore, it must have sufficient strength and rigidity, simple structure, and good manufacturing technology.
