history of the development of chinese amusement facilities
china's amusement industry started relatively late. before the 1980s, modern large-scale amusement facilities were almost blank in china. it can be traced back to the electric small chair designed and manufactured by beijing machinery factory in 1951 and installed in beijing zhongshan park. it may be china's first amusement machine. in the early 1980s, with the deepening of reform and opening up, the national economy developed rapidly, people's living standards continued to improve, and people's demand for amusement activities became more and more vigorous. in this situation, the design and production of domestic amusement facilities came into being. with the development of the amusement industry, china's amusement facilities have continuously improved from design to manufacturing. there are more and more varieties, from rotating to sliding, from power to no power, from stationary to mobile, from the ground to the air, from indoor to outdoor, from the previous single to the integrated type. however, it has not been regulated in national standards.
the latest specifications for rides
the latest safety standards for rides are the "safety regulations for recreation facilities" implemented on august 1, 2008.
many lag clauses have been removed and many new requirements have been added. the main changes are reflected in five aspects.
first, the acceleration allowable value is added to the sliding class, such as the "roller coaster". this is because when the "roller coaster" descends from the highest point to the lowest point, the speed is very fast and the acceleration is large. in order to prevent the passenger from being harmed, the acceleration should be limited to a certain range.
second, various loads have been added, such as wind loads. because when the wind is above the sixth level, the speed of the own is combined with the impact force. it is very dangerous for the passenger to be thrown out. it is necessary to stop the ride. running.
third, the safety factor has been adjusted and reduced. originally, a common material can meet safety requirements, and there is no need to use special materials. in the past, the safety factor was set too high, resulting in waste of materials and an increase in cost.
fourth, new requirements for safety assessment and safety analysis have been added.
fifth, increase the safety standards for water amusement facilities
