Evaluation of the Reliability of the Shoulder and Knee Joint of the KPSIT C50 Dummy Adapted to Crash tests carried out at low speeds.

Abstract

The article presents the results of experimental studies on the reliability and monitoring of the condition of the knee and shoulder joints of an anthropometric dummy designed for low-speed crash tests. Next, the characteristics of the resistance moments in the joints of the KPSIT C50 dummy are compared with the characteristics of the drag torque of the HYBRID III C50 dummy. The patented and manufactured knee and shoulder joints of the KPSIT C50 dummy characterized by a simple structure. The article presents a comparison of the resistance moments in the knee and shoulder joints of the KPSIT C50 dummy before crash tests and after a series of 200 crash tests. It has been shown that the patented solutions that have been used for low-speed crash tests do not need to be calibrated after a series of 5 crash tests, as is the case with the Hybrid III dummy. In addition, the results of experimental research presented in the article confirm the durability of the KPSIT C50 dummies joints and the possibility of using the joints for other centiles of anthropometric dummies.

Finding the Correlation between Transport Infrastructure and the Fatal Accident Rate of Cyclists—An International Perspective

“…Jaśkiewicz et al (2021) highlights the development of an anthropometric dummy for low-speed crash tests, emphasizing its relevance to assessing bicycle safety at speeds up to 30 km/h where standard dummies are inadequate. Jaśkiewicz (2024) discusses the durability of knee and shoulder joints in the new dummy model, suggesting its potential in enhancing safety measures for bicycle transport through reliable joint mechanisms.…”
