Sentence examples for wheel impact from inspiring English sources

In this study, nonlinear dynamic finite element is used to simulate the SAE wheel impact test.

The wheel impact test is intended to evaluate the impact performance of wheel, that the striker is dropped from a specified height above the tire wheel assembly.

Experimental design was split-plot, with the main plot being position of wheel impact and the plot being split by varieties.

In service, the flated wheel impact circularly against the rail, resulting in the large wheel rail impact force and high-frequency vibration, which will bring severe damages to the wheelset, rail and track structure.

It is shown that the von Mises equivalent stress and maximum shear stress are in a small fluctuations before 2.1 ms and then experience a sharp increase to the corresponding maximum values of 672 and 382 MPa at approximately 3.0 ms (the wheel impact against the rail), followed with great fluctuations.

Thus the wheel impact of vehicles may be somewhat different than in agriculture and forestry.

The aim of this study was to determine the response of the human chest in a set of simulated steering wheel impacts.

Three-dimensional finite element method is employed to obtain the strain energy density of wheel at impact, and the critical strain energy density is based on the total plastic work of wheel material.

The results show that the maximum vertical wheel-rail impact force induced by the wheel flat is higher than that generated by the perfect wheel, and these two dynamic impact forces are much greater than the static axle load.

Besides, the maximum von Mises equivalent stress and maximum equivalent plastic strain are observed on the wheel-rail contact surface, and both of them as well as the maximum wheel-rail impact force are sensitive to train speed, flat length and axle load.

Influences of the train speed, flat length and axle load on the vertical wheel-rail impact response were discussed, respectively.
