摘要
本文以大型过山车为研究对象,基于游乐设施剩余寿命评估理论,从疲劳、磨损和锈蚀这三个影响大型游乐设施主要受力部件剩余使用寿命的因素出发,对四环过山车车体的重要结构件和重要销轴进行了应力测试和尺寸测量,以测试和测量数据为基础对其进行了疲劳寿命分析、磨损和锈蚀寿命分析,得到了车体重要结构件和重要销轴的剩余使用寿命,进而得到了四环过山车车体的剩余使用寿命为1×105次,折算后的使用期限约为5年8个月。
This paper takes the large roller coaster as the research object.Based on the evaluation theory for the remaining life of amusement ride,the research is carried out from fatigue,wear and corrosion,which are three factors affecting the remaining service life of the main load-bearing parts of large amusement ride.The stress test and dimension measurement is carried out for the important structural parts and important shafts of the four-ring roller coaster body.Based on the test and measurement data,the fatigue life analysis,wear and corrosion life analysis for important structural parts and important shafts are carried out,and the remaining service life of important structural parts and important shafts of the roller coaster body is obtained.Based on this,the remaining service life of the fourring roller coaster body is 1×105 number of runs,the service life after conversion is about 5 years and 8 months.
