| Abstract: | Virtual prototype technique was applied to study the safety of roller coaster for solving the defects in its traditional design, reducing its design cost, and improving its safety. A virtual prototype of roller coaster was constructed using ADAMS software. The impact of the diameter of circular ring track, the carriage weight, and the brake force on the safety of roller coaster was studied to obtain the rational range of above-mentioned parameters. The power condition of the linkage between two carriages and the acceleration got improved, and the precision of brake force got raised. This approach provides a new way to explore the safeguard technique of special sports equipment, the roller coaster. |
