The facilities using LP gas in camping vehicles, which are exposed to safety problems due to the proliferation of domestic leisure culture, are not subject to statutory inspection so, effective safety management measures are needed because the subject or method of safety management is ambiguous. In this study, we tried to propose the safety management measures through the deduction of representative types of camping vehicles, research on the actual condition of LPG facilities in camping vehicles and investigation and review of relevant regulations. Through the results of this study, we expect to contribute to the improvement of the safety management efficiency and safety of facilities using LP gas in domestic camping vehicles.

Purpose: This research is to develop Trailer Durability Test of towing device, in order to cover usage conditions of bike type as well as general type trailer. With the diversification of leisure activities, the population that enjoys various sports and leisure has increased rapidly, and the number of vehicles equipped with camping trailers and bike carriers is also increasing steadily. The purpose of this study is to develop a durable vehicle that has no problem in various customer conditions. Methods: We measured the input load under various conditions of the user by attaching load cell to the body fixing part and towing ball of the towing device. The load in various modes was measured, and the difference between the trailer and the bike carrier type was compared and analyzed. Results: Due to the difference in fixing method and weight between the two types, the trailer has a large longitudinal force and the bike type has a large vertical force. Therefore, it is necessary to durability test method capable of satisfying all longitudinal force and vertical force. Conclusion: We improved the durability test of the towing device by changing the test surface. The new mode has made it possible to shorten the durability test schedule by increasing test efficiency.
