In order to further improve the safety performance of passenger vehicles, the newly revised “Classification and Rating of Operating Passenger Cars†(JT/T325-2013) standard has been officially released on May 1st this year. The safety of passenger cars of various grades has been Energy-saving environmental protection, comfort and other related configuration and performance indicators timely raised higher requirements, such as the requirements for the installation of front-wheel tyre burst emergency safety devices for passenger cars in large passenger cars and large low-drive areas. Conscientiously implementing the JT/T325-2013 standard will help promote technical upgrading of road passenger vehicles and guide the healthy development of China's passenger vehicle industry.
As early as 2012, the Ministry of Industry and Information Technology issued a notice to improve the safety and technical performance of large and medium-sized passenger vehicles, which clearly stipulates: “As of March 1, 2012, the new stereotypes of road buses and coaches with a vehicle length greater than 11 meters should be Full load integral frame structure."
In fact, in terms of security, the full load bearing technology has long been recognized by the national authorities and the passenger car industry. In China, the application of full load body technology has triggered a technological change in the domestic passenger car manufacturing industry. Full-load passenger cars have also gradually been recognized by our customers. Many provinces regard full-capacity passenger cars as the main direction for selection, and encourage passenger transport companies to purchase full-capacity passenger cars.
The full load-carrying body adopts a closed loop structure, and since there is no frame, the height of the floor and the entire vehicle can be reduced. Its advantages are: reduced body weight, increased structural strength and stiffness, greater load capacity, less frequent vehicle start-up and brake vibration, which can reduce the extent of component damage, improve vehicle reliability, and reduce maintenance costs; Simplify the molding process of the components and improve the material utilization rate. The vehicle has a low center of gravity and high-speed stability. Its greatest advantage is its good passive safety. According to the passive safety test of passenger cars in Europe, this structure can guarantee passengers' safety space when the car rolls and collides. It is these unique advantages that make it the world leader in passenger car technology, which has led to a revolutionary change in the development of the world bus.
As the first bus company in China to introduce full-loaded bodywork, Ankai Bus has become an important milestone in the development of luxury passenger cars in China. The successful launch of a new generation of luxury passenger car products has sparked a technological revolution in Chinese passenger cars, which not only has driven Chinese passenger car technology. The advanced level in the world has driven the development of China's high-speed passenger transport industry, and has also promoted the simultaneous development of China's expressways.
In addition, according to the "Classification and Assessment of the Types of Passenger Cars" issued by the Ministry of Communications, high-class passenger cars must adopt a fully-loaded structure. The implementation of this standard will surely promote the development of China’s all-cargo passenger car market and mobilize the enthusiasm of bus companies for developing fully-loaded buses. Undoubtedly, in the past two decades, the products and technologies of Chinese passenger cars have developed leaps and bounds. The technical content of passenger car products has become higher and higher, humanity considerations have become more and more considerate, and under the guidance of national policies, the standardization of passenger car products has been achieved. The degree is gradually increasing. In the final analysis, these changes are achieved through the expansion of the market to guide the escalation of demand. For bus companies, product development is market-oriented to support the growth of business performance. The appearance of a full-capacity passenger car has adapted to the current development trend of the passenger car market and satisfies the public's demand for safety, comfort and energy-saving buses. The all-cargo passenger car has keenly grasped the market opportunities and gradually narrowed the technological gap between Chinese passenger cars and Europe and the United States. On the one hand, the competitiveness of all-passenger passenger car products has gradually increased. On the other hand, the market position of all-car carriers is also increasing.
Adopting a full load bearing structure, the passenger car has more agility, stability, comfort and safety, coupled with its low floor design, humanized configuration, low emission, environmental protection, passenger space and other advantages, reflecting the modern The social advocacy of "leading technology, people-oriented" concept has also created the unique product advantages of all-cars.
The full load-carrying body has no traditional chassis girder structure, which further reduces the height of the car body, especially the height of the chassis. The highly effective control of the first step is within 360mm, making it a true "low-entry" concept for passengers to get on and off the car. The fuel consumption of the vehicle can be reduced. Due to the use of the full load-carrying body structure, finite element analysis and calculations are performed during design to optimize the body structure. Compared with similar domestic passenger cars, the weight of the entire vehicle is lighter, not only reducing the manufacturing cost of the manufacturer, but also At the same time can reduce the user's cost of use; comfort, low noise, low vibration, all connected parts of the body and chassis are welded together, forming a whole, there is no relative movement, no noise, compared to other In the form of a body, there are many noise sources.
The current passenger car design and layout of the car is an overall trend, passenger cars need to function to "people"-oriented. After years of marketing, all passenger cars have been recognized by domestic consumers in terms of safety and comfort.
Through the implementation of the JT/T325-2013 standard, it also strongly promoted the upgrading of road passenger vehicles, speeded up the adjustment of the vehicle structure, further improved the safety of passenger vehicles, reduced the fuel consumption of vehicles, and provided even greater travel for the people. Safe, reliable, fast, and comfortable means of transportation has enabled the people's travel to change from "going well" to "going well."
After years of marketing, the high safety and economical efficiency of all-passenger buses has been recognized by domestic consumers. The development of the classification and rating management of operating passenger buses will certainly play a significant role in improving the level of technical equipment of road passenger vehicles, ensuring transportation safety, and improving passenger service quality.
Sms Spunmelt Nonwoven Production Line
The sms non-woven fabric production line is used to produce polypropylene fiber spun webs and hot-rolled reinforced non-woven fabrics.
