面向汽车儿童约束系统翻转试验的设备方案优化设计

he objective of the study is to form a scheme or devise a system for child restraint system's rotation test and to design the proper equipment used for the test process. The requirements for the rotation test equipment include test bench's changing direction in 90 automatically, thus avoiding the potential safety hazard often caused by changing direction manually which is a common practice in the operation of similar domestic equipments. The scheme of the equipment mentioned in this paper is based upon the concept of modularity design, and militates in favor of achieving the state that the shape and structure of the equipment is simple, while it's more reliable and easier to operate and upgrade. In the paper the function of test bench's changing direction automatically is achieved in the control of light activated switch and the relevant controlling circuit. In addition, the relevant content of national standards is interpretated and studied in the paper. Finally in the conclusion part, problems often arising in rotation tests and other schemes for the equipment are discussed, and the relevant proposals for improvement are offered in the paper.
