Vibration performance analysis of vehicle with the non-pneumatic new mechanical elastic wheel in the impulse input experiment

Abstract

A non-pneumatic tire appears to have advantages over the conventional pneumatic tire in terms of flat proof and maintenance free. A mechanical elastic wheel (MEW) with a non-pneumatic elastic outer ring which functions as the air of the pneumatic tire was presented. The structure of MEW is non-inflatable integrated configuration and the effect of hinges is accounted for only in tension. To establish finite element model of MEW, various nonlinear factors, such as the geometrical nonlinearity, material nonlinearity and contact nonlinearity, were considered. Load characteristic test was conducted by tyre dynamic test-bed to obtain force-deflection curves. And the validity of the finite element model was validated through load characteristic test. The vehicle vibration performance respectively based on the MEW and the radial tire was compatative studied under pulse input experiment conditions. The result showed that the vehicle concluding the new mechanical elastic wheel met the vibration performance requirements and vibration performance regularity of pneumatic tire. The results could be used as the thesis reference for the improvement of new mechanical elastic wheel.

Topology optimization on metamaterial cells for replacement possibility in non-pneumatic tire and the capability of 3D-printing

“…Usually, the vertical force applied to a tire is determined based on the rated load of the tire. However, in the research related to NPTs [5,6,9,[11][12][13]17,20,22,[24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39], various forces from 0.5 to 35 kN were used for different analyses. The car considered in this research was a passenger car.…”

“…NPTs have a wide range of potential applications among which their use in wheelchairs, space probes, cars, trucks, bicycles, can be pointed out [11]. Various architectures of NPTs have been designed and studied in the past, including Tweel [12][13][14][15][16][17][18][19][20][21][22][23] and Mechanical Elastic Wheel (MEW) [24][25][26][27][28][29][30][31] tires, which are extensively researched and presented in S1 File.…”
