Developed 4.0m/s high speed and high-quality traction elevator and its field testing
Key Technology and Achievements：
A time-varying element model of the hoist cable-car system was proposed by modeling the system as a moving elastic string. According to the Lagrange method, the horizontal nonlinear dynamic equation with time-varying parameters for high speed traction elevator was derived.
The SEA model for predicting the noise in the high speed traction elevator car was built.
After the research results were applied in production, the cost of the dynamics behavior testing for high speed and high quality traction elevator was reduced about 30%, and its development cycle was reduced about 40%.
Corresponding research results of this project acquired the Science and Technology Progress award of Zhejiang Province in 2012, level 1.
