In the 1980s, the energy crisis caused the shortage of oil resources in various countries all over the world, which led to the research on the application of lightweight technology in the field of automobile. Some developed countries have formulated and adopted some mandatory laws, regulations and rules on how to solve the problems of lack of local resources and deterioration of environmental pollution. In response to the national call, major brand automobile manufacturers began to develop new materials that can save energy, protect the environment, be applicable to lightweight and recyclable, and invested a large number of scientific and technological talents and advanced equipment. At the same time, governments have allocated funds to some domestic enterprises, colleges and universities and research institutions to support the R & D of automotive lightweight materials and promote the development of automotive lightweight technology.
Nowadays, the problem of environmental pollution is becoming more and more serious. Energy conservation and environmental protection have become a common concern and urgent problem to be solved all over the world. Low carbon consumption of automobile is the key link to reduce emissions and save energy in the whole design field. It is estimated that if the total weight of the vehicle is reduced by 1 / 10, the oil consumption can be reduced by 8%; At the same time, the cost performance of oil increased by 7%. Therefore, reducing pollution emissions, saving energy and reducing body weight are inseparable.
At the same time, agriculture is an important basic industry in China. Agricultural mechanization generally replaces manual operation, reduces costs and brings economic benefits. The application of lightweight technology to agricultural machinery can reduce the weight and fuel consumption, and it is more convenient to work together with agricultural machinery. From the long-term development of the country, it saves energy and protects the environment. At the same time, the production cost of farmers is reduced, the R & D and creation time of scientific researchers is greatly reduced, the R & D cost is greatly reduced, and the competitiveness of the consumer market is also improved.
Titanium alloy has good properties in all aspects and has great advantages over other materials. It has the advantages of light weight, low density, high yield strength, high temperature resistance and good corrosion resistance. It is suitable for agricultural machinery. By reducing the weight of agricultural machinery working parts and alleviating the load capacity of relevant structural parts of the frame, and improving the internal engine performance, it can well reduce the body vibration during agricultural machinery operation and improve the work efficiency.
The performance of titanium material in environmental protection is also good. Because it has the characteristics of new materials, it has also attracted the attention of automobile manufacturers all over the world. The density of titanium material itself is not high, and the density value is between the density value of aluminum material and iron material. Agricultural machinery will also have a significant effect when it is applied to the manufacturing and design of various parts. Nowadays, the use of titanium materials in engine systems and production parts of all kinds of brand cars is also common.
Titanium material is also widely used in vehicle exhaust system.The parts designed and made can be half lighter than those made of other materials. Under the condition that the stability and strength of production operation remain unchanged, the lighter the weight, the faster the speed, and save fuel. Nowadays, titanium processing technology is more and more complete. Some improved processing equipment and tools can accurately process large structural parts and components, which greatly improves the efficiency of processing and manufacturing.
Although the vehicle lightweight technology develops rapidly, titanium alloy is not widely used in the domestic manufacturing industry. The most fundamental problem is that titanium alloy materials are expensive, the processing cost of various parts is high, and the welding technician is poor. In the future development trend, if we can reduce the R & D cost of raw materials, reduce the sales price of titanium parts, and improve the performance of titanium alloy through effective processing methods, we can promote the application and development of titanium alloy in various fields.
