Automobile and its spread Sometimes the complicated logistics network of parts suppliers, assembly plants and dealers, the automobile industry may be particularly vulnerable to natural disasters and other disasters.
Automobile industry is a huge and sometimes chaotic industry composed of countless parts suppliers, assembly plants, logistics networks and dealers, which may be particularly vulnerable to natural disasters or other disasters.
Manufacturers are familiar with the interruption of production caused by floods, snowstorms, landslides and forest fires. Dealers have seen their new car inventory destroyed by overflowing rivers, surging tides and punitive hail.
Automobile manufacturers are well aware of the impact of floods, snowstorms, mudslides, forest fires and other disasters on automobile production. Many dealers have experienced the situation that the automobile inventory was swallowed up by floods and angry tides or damaged by hail.
The disaster even happened at sea. In 2002, a Norwegian transport ship carrying 2862 cars collided with a container ship in dense fog and sank in the English Channel.
Disasters can also happen at sea. In 2002, a Norwegian cargo ship carrying 2,862 cars collided with a container ship in dense fog and sank while crossing the English Channel.
But there is nothing like the triple threat brought to Japan by last week's earthquake and tsunami, and the growing concern about the meltdown of nuclear reactors.
However, compared with Japan after the earthquake, these are insignificant. Last week's earthquake in Japan, the tsunami caused by the earthquake, and people's growing concern about the meltdown of nuclear reactors in the earthquake zone have brought triple threats to Japan's automobile industry.
As the third largest automobile producer in the world (next to China and the United States), Japanese manufacturing network is highly developed and extremely complex. The natural limitations of Japan's crowded highways and seaports, coupled with artificial complex factors such as on-time parts delivery, have led to the emergence of a fine-tuning and delicate balance system.
As the third largest automobile producer in the world (next to China and the United States), Japanese automobile production network is highly developed and particularly complex. The highways and seaports in Japan are very crowded. Which one is Japanese? Congenital deficiency? In addition, there are many artificial complex factors in Japanese automobile industry. For example, many Japanese manufacturers have adopted parts transportation? Zero inventory? Real-time transmission system. These factors make Japan's automobile industry an extremely fine and highly balanced system.
Smooth operation and high production efficiency. But a single interruption anywhere on the production line may affect the whole system. It takes about 10000 parts to assemble a car, and each part is necessary for the finished product.
If it works normally, it is an extremely efficient system. However, if one chain in the system breaks, it will affect the operation of the whole system. It takes almost 65,438+00,000 parts to assemble a car, not one of them can be missing.
Cars have a long history. French engineer Nicolas Joseph Kueger did not build the first self-propelled vehicle (Paris 1789). A heavy-duty three-wheeled steam-driven carriage with a prominent boiler in front; Its speed is 3 miles per hour (5 kilometers per hour). 180 1 year, British engineer Richard Trevithick also built a three-wheeled steam car; The engine drives the rear wheels. Due to excessive supervision, the development of automobiles was delayed for decades: the speed was limited to 4 mph (6.4 km/h) until 1896, when a person was required to walk in front of a self-propelled vehicle and hang a red flag during the day and at night. The Stanley brothers in Massachusetts are the most famous steam car manufacturers in the United States. They started producing Stanley steam engines from 1897 until the end of World War I.
The introduction of internal combustion engine accelerated the development of automobile. The first car of this type may be a three-wheeled car made by German engineer karl benz in 1885. Another German engineer, gottlieb daimler, made an improved internal-comb internal-combustion engine c. 1885. The Panhard car launched by Daimler in France on 1894 has many characteristics of modern cars. In the United States, Charles delia and J. Franck delia elwood Haines Henry Ford Lanson E olds and alexander winton built a four-carriage diesel locomotive without horses in 1960. Many early engines had only one cylinder and were driven by chains and sprockets on wooden wheels. This kind of car is usually open, can accommodate two passengers and is operated by a lever.
The free development of automobile industry in the early 20th century. Threatened by the patent of American inventor george selden 1895. Several early manufacturers authorized by seldon formed an association in 1903 and took over the patent in 1907. When the U.S. Court of Appeals for the Circuit ruled that the patent was valid, but only covered two-stroke engines, Henry Ford, the leader of a group of independent manufacturers who refused to recognize the patent, started a lawsuit with seldon and the Association from1903 Until1911; Most cars, including Ford, use four-stroke engines. Subsequently, the mass production of automobiles and the construction of highways connecting cities and suburbs, regions and regions changed the face and society of the United States.
Cars have a long history. Nicolas Joseph Cugnot, a French engineer, built the first bicycle (Paris, 1789), which is a heavy three-wheel drive steam boiler and is expected to be in the front of the carriage. The speed is 3 miles (5 kilometers). In 180 1, British engineer Richard? Trevithick also made a three-wheeled steam car; The engine drives the rear wheels. For decades, the development of automobiles has been over-regulated: the speed was limited to 4 mph (6.4 km/h) until 65,438+0,896 people were required to walk in front of bicycles and carry red flags and lanterns day and night. Stanley Brothers, Massachusetts, the most famous steam-driven automobile manufacturer in the United States, from 1897 to Stanley steamship after World War I.
The introduction of internal combustion engine accelerated the development of automobile. Perhaps the first car of this type was a tricycle built by German engineer karl benz at 1885. Another German engineer, gottlieb daimler, made an improved internal combustion engine c. 1885. Che 'an imported 1894 from Daimler of France, which has many characteristics of modern cars. In the United States, there are Charles delia and J. Franck delia, elwood Haynes, and Henry Ford. What do you do in ransom? Oz and Alexander? Winton. Many early engines had only one cylinder, and the chain and sprocket were driven by wooden wheels. Cars are usually open, accommodating two passengers and operated by levers.
The free development of automobile industry in the early 20th century. By American inventor George? Seldon's patent threat, published in 1895. Several early manufacturers authorized by Selton established an association in 1903 and took over the patent in 1907. Henry Ford, the leader of a group of independent manufacturers who refused to recognize the patent, is suing Selton and the association from 1903 to 19 1 1. The U.S. Court of Appeal ruled that although the patent was valid, it only contained two strokes. Most cars, including Ford, use four-stroke engines. What followed was the mass production of automobiles, and later roads connected cities with suburbs and regions, thus changing the face and society of the United States.
A small car may replace the present big car. If people drive such cars in the future, the pollution in the air will be reduced.
There will be more parking spaces in the city. The streets will no longer be crowded. It will be safer to drive, because the speed of these cars is only 65 kilometers per hour.
The future car is very suitable for driving in the city, but not for long-distance travel.
The car needs to stop to refuel after 200 kilometers. If large cars are still used with small cars, two sets of roads will be needed in the future. Roads will be used for large fast cars, and other roads will be used for slow and small cars.
It is said that an American-sized car can accommodate three such cars now. There is a kind of car that may replace today's carts one day. If people drive such cars in the future, the pollution in the air will be reduced.
There will be more parking spaces in the city. The streets will no longer be crowded. And it will be safer to drive, because these cars can only walk 65 kilometers per hour.
The cars of the future can drive in cities, but they are useless for long-distance travel.
The car will walk 200 kilometers and need to refuel before. If the large car is still used with the car, two routines will be needed in the future. Roads will be used for large fast cars, and other roads will need to be slow and small.
It is said that one car is suitable for three such cars now, and this is the usual size.
