Abstract
The mechanical strength is an important performance for elevators, and it is directly related to the safety of the elevator passengers. Standard regulations has strict technical requirements for this performance in China. In this paper, a novel inspecting method based on strength-deformation synchronous measurement is proposed for carrying out quantitative testing of mechanical strength in elevators. In order to optimize the accuracy of the system, the measurement instrument performs Kalman filtering on the pressure sensor data during the measurement process to make the data smoother and closer to the real value. The processed data is then used in displacement measurement methods to obtain the elastic deformation and permanent deformation data of the elevator shaft wall. Experimentation is conducted to verify the validity of the proposed method with high accuracy in elevators.
