Purpose meaning

This standard as a safety standard for large amusement rides, is also the main basis for the revision of other standards for amusement rides, which guides the design, manufacture, use, inspection and other aspects of amusement rides. This standard as the most important standard of the amusement ride industry, to protect the quality of equipment and operational safety for the purpose of promoting the healthy and orderly development of the industry, to ensure the safety of people's lives and property, with important social and economic benefits.

Main content

The "Safety Code for Large Amusement Rides" is based on the original 2008 version of the "Safety Code for Amusement Rides" with the addition of the word "large", the new standard chapter 4 "General" section increases the number of new processes, new methods, new materials and new rides beyond the The solution of the standard provisions, increased the requirements of the risk evaluation; 6.8 "bearing system" increased the requirements of the seat belt buckle components, increased the selection requirements of the restraint device, according to the acceleration area set up 5 levels of restraint device.

Compared with GB 8408-2008 "amusement facility safety specification", specifically in the following four parts of the main revision:

1, the overall framework

The new version of the standard in accordance with the general principles, materials and fasteners, design, manufacturing and installation, use management and maintenance organization. This arrangement and product design, manufacturing, use, maintenance process order, covering the entire life cycle of the equipment, logical and reasonable, easy to use and find. In addition, the "risk assessment" part into the general rules, highlighting the core position of risk assessment in GB 8408.

2、Carrying system

In response to the problem of more accidents related to passenger restraint devices, this revision puts forward the concept of occupant system for the first time, specifying that the occupant system includes occupant devices and passenger restraint devices (such as seat belts, safety bars, gear bars, etc.). Increased the technical requirements for passenger devices and passenger restraint devices. According to the design acceleration divided into 5 levels, clear the corresponding level of passenger restraint device selection requirements.

3、Welding and important welds

For amusement rides welding quality is unstable, safety hazards, more controversial important welds and other issues, increase and clarify the design principles of welded joints, welded joint type, welding seam classification, welding node construction requirements, weld strength calculation, weld testing requirements. Proposed weld seam should be determined by risk evaluation of its level. Risk evaluation needs to consider the possibility of failure of the weld, the severity of the consequences of failure, the testability of the weld and other factors. The weld is divided into four levels by risk evaluation, and depending on the level, the weld performs the corresponding proportion of visual inspection, surface nondestructive testing or internal nondestructive testing, etc.

4、Design calculation aspect

For the permissible stress method based on the breaking strength in large equipment limitations and other issues. The new version of the standard proposed part of the calculation can be used limit state design method, on the basis of ensuring safety, the introduction of other mature structural design calculation methods. In the design calculation to properly reduce the impact coefficient requirements, increased the vibration coefficient requirements for track-type equipment. The analysis of working conditions of amusement facilities is clarified (including normal operating conditions, abnormal operating conditions and limit state conditions), and the formula for calculating the load combination is put into the appendix.
