“…In the real testing condition, the response equation (Equation 8) is always ill‐posed, and a small fluctuation in R may result in considerable errors in the solution of Φ . Fluctuations in response are inevitable because of the dynamic effect, 25 the road irregularity, 26 and other factors 27 . Therefore, the real measurement R can be expressed as the sum of the following two parts:

R_{r} bold= R_{real} bold+ bolde

where R real represents the ideal static response of the bridge and e represents the errors.…”

Summary Bridge influence surface is an important tool to study the bridge responses under the moving loads, which contains tremendous structural information. The structural deterioration during the service life would induce the variation of the bridge influence surface, which makes it essential to identify the influence surface exactly from the field measured data under moving vehicle loads. This paper firstly summarizes current development of bridge influence surface identification methods and classifies the methods in which the vehicle is respectively equivalent to line loads and concentrated loads. After that, the actual spatial distribution of the vehicle load is considered, based on which a new identification method is presented to solve the boundary problem of current influence surface identification methods. Then a numerical slab model with two fixed ends is illustrated to prove the validity of the method, and the accuracy and identifiable region of different methods in this condition are compared with the other methods. Influence factors of identification accuracy including noise level, axle number of vehicle and loading point are analyzed. Finally, laboratory verification using the same slab model is prepared to verify the effectiveness of the proposed identification method. Results of this study provide an effective identification method of bridge influence surface with very high identification accuracy, which can be used to full bridge influence surface test.

“…Of course, it seems important to be acquainted with the problems of road irregularities, especially when the randomness is taken into account. Some works, including, e.g., [15][16][17], have been devoted to these problems. Some papers have been devoted to more specific aspects, such as determining the road conditions via a signal obtained from the vehicle [18], using measurements for vehicle dynamics simulations [19], or nonlinearity included in the problem of the wheel -road contact phenomena on a randomly uneven road [20].…”

In the paper, some selected results concerning the ellipses of adhesion for various conditions of motion of a vehicle model, have been presented. The analysis, regarding the phenomena between the road and the wheels of the given motor vehicle's model, was previously carried out in the earlier paper by the author. However, they proved useful for the second part of research based on determination of the ellipses of adhesion. This can enable answering the question whether the road conditions may affect the maximum longitudinal and lateral forces combining such ellipses in the contact plane between the road and the wheels. The analysis has been presented based on the previously obtained results.
