Wall Mounted Bike Rack The Strength Of The Increase

Runva Enterprises Limited | Updated: Aug 04, 2017

In general, the rigidity of the frame is determined by the elastic modulus of the material, the elasticity coefficient of the steel is 30, the aluminum is 10-11, the titanium 15-16.5, Wall Mounted Bike Rack so when the pipe diameter and wall thickness are the same, the rigidity of the aluminum frame is only steel frame One-third of the rigidity of the titanium frame is only one-half the steel frame. Frame strength is determined by the strength of the material, the strength of the reduction and the quality of the frame pipe, heat treatment process and alloy composition has a great relationship. Aluminum precipitation point only 11-59, titanium 40-120, steel 46-162, Wall Mounted Bike Rack compared to aluminum is more fragile and vulnerable. In the actual design, each frame of the pipe diameter will determine the size of the frame stiffness, strength and weight, pipe wall thickness will also affect the frame strength and weight. Some of the most suitable design of the frame in some places emphasize rigid, in some places to strength, Wall Mounted Bike Rack in some places to shock, it must be in different functional demands of the site with the appropriate material, and the combination of different materials technology is also a major test.

Steel is the longest used in the bike frame material, the main advantages include long ride riding rigidity, pipe elasticity (shock), pipe joints and more processing and easy to weld and do not need heat treatment, so the cost and The price is relatively low. The disadvantage is the weight is too heavy, Wall Mounted Bike Rack improper maintenance easy to rust, pipe shape is not easy and metal fatigue problems. However, many of today's alloy steel has been in the rigid, elastic coefficient, transmission, stability, very good results, the only fly in the oder is still heavier weight. Steel molybdenum steel in the most common, high strength and easy to pump processing. Molybdenum can improve the strength of steel to prevent brittle; chromium can make steel corrosion resistance, Wall Mounted Bike Rack rust and prevent high temperature oxidation. Many handmade steel pipe proponents of the most recommended is its excellent sense of road and suitable for long-distance riding the comfort of the advantages, as the steel gourd said: "steel forever, Wall Mounted Bike Rack a perpetuating!" Suitable for use in BMX actually Car, long distance wagon and truck.

Aluminum alloy is currently the most common use of the material on the market, Wall Mounted Bike Rack the advantage is light weight, short hardness and rigidity of the best performance, easy to shape, not rust, light to the tube can be very thin, The use of CNC die cutting to make exaggerated appearance and amazing strength. Disadvantages are almost no flexibility at all, will accumulate metal fatigue, but also because of its Ning Min light, high rigidity characteristics, it is easy to convey the ground vibration, resulting in poor riding comfort. Wall Mounted Bike Rack Aluminum frame in early 1990 began to popular, since 1995 began to universal, the general use of 6061 and 7005 aluminum alloy alloy frame. The aluminum alloy is suitable for use on racing, Enduro and Downhill models. Huge Technology Center pointed out that compared with the AL7005 will have stress corrosion and welding hot cracking problem, AL6061 in the use and process are more stable, but the heat treatment is more complex.

Carbon fiber is not a metal, but a composite material, the use of carbon fiber woven into a cloth, after the process of prepreg resin into a prepreg, and then pre-dip cloth and then laminated into the mold heating molding, according to demand Various shapes of the frame. Its characteristics are lightweight, Wall Mounted Bike Rack more elastic (shock absorption good), riding a sense of stability, long-distance tracking continued good feeling, high comfort, process changes, but the surface hardness is poor, when the external force is higher than its damage strength When it will cause a break. Moreover, in recent years due to the increasing demand for carbon fiber yarn, resulting in material shortages, so the price is high. Carbon fiber tensile strength is strong, Wall Mounted Bike Rack but the shear strength is weak, the processing needs to be complex stress calculation (longitudinal rigidity, transverse rigidity), according to the calculation of carbon fiber sheet overlap forming. Generally referred to the high modulus (Hight Module, HM), Wall Mounted Bike Rack refers to the high tensile strength of carbon fiber material. The same time as

At present, Wall Mounted Bike Rack the forming method of carbon fiber pipe is formed by one molding, 3D weaving injection and the so-called tube-to-tube mode, and the future trend will be developed towards the integration design of tube-to-tube integration. Currently on the market has developed nano-carbon fiber technology, Wall Mounted Bike Rack abandoned generally used in general carbon fiber epoxy epoxy resin, instead of a kind of cemented carbon fiber 2 woven special nano-material, and can be said to make the impact of a full impact 40% more than traditional carbon fiber! In general, Wall Mounted Bike Rack carbon fiber is more suitable for use in the demand for less resistance to the timing of the car.
