The algorithm of analysis of systems that have disruptable constrains is described in the article. The algorithm is based on the joint solving of two linear systems. The first linear system is the one that describes the processes before constraints get disrupted; the second linear system represents the system describing the processes in the aftermath of disruption of constrains with account for the influence of free vibrations. Free vibrations are caused by disrupted constraints. The proposed approach is more effective, if applicable to the systems that have their constraints disrupted only once. Also, the method describing disrupted constraints is considered as a special case of physical nonlinearity. Physical non-linearity adds some fictitious load to regular loads.
Formulas of equivalent static loads, with the help of which the systems are analyzed when constraints are disrupted, are generated. No inertial force is to be derived to obtain equivalent static loads. This is important in view of their application in dynamic analyses .
Analysis of the static system in the event of disrupted constraints is based on the equations derived by the authors. The result of the analysis represents an inverse linear relation of static loading and relative stiffness of the system with disrupted constraints. This means that the lower the stiffness of the system, the higher the static loading.

The authors present analytical and numerical solutions to the problem of vibrations of deep foundations caused by dynamic loads, if the foundations rest on multilayer soils. It is proven that the friction force that influences the foundation, the weighty nature of the bedding, and the visco-elastic properties of soils affect the amplitude and the frequency of vibrations.
The authors present an approach to the calculation of vibrations of deep foundations resting on multilayer soils. The proposed approach takes account of the side surface friction of the foundation and the soil and elastic and viscous properties of soils. The soil is presented as a multilayer substance, and all of its layers are connected to one another by elastic-viscous elements. In this case, each layer of soil vibrates independently and provides multiple degrees of freedom to the system.
A mathematical description of vibrations requires the identification of the coefficient of stiffness for each layer of soil, as well as the weight, the average per-layer stress and the angle of distributed static stress.
The results have proven that the weight of the bedding, the friction of a deep foundation, and elastic and viscous properties of soil affect the behavior of the amplitude and the frequency of foundation vibrations and the accumulation of residual settlements.

The increase in noise level at cities is increasing the requirements to functional interaction of road users - pedestrians and drivers - with the parameters of the environment as a leading component of Afferentation synthesis in the complicated complex of locomotive activity. City noise is one of the most widespread factors of unfavorable living and working conditions. The noise of high intensity provokes diseases, lowers labor activity. At present, many large cities pay much attention to electric vehicles. The authors present an analysis of the poor state of tram track in areas of high noise and vibration of car and under-sleeper base design. A negative effect of noise and vibration on the formation of urban areas environment is shown as well as the impact of these conditions on the person. The advantages of the application of electric transport are specified, noise displacement curve of railway and under sleeper base is plotted depending on the frequency of the applied load and the modulus of elasticity, as well as under sleeper base vibroacceleration depending on time. The authors offer a systematic study on the basis of a mathematical model of the sources of noise in the process of a tram motion.

The authors describe the methodology and results of dynamic field testing of the building of a universal pool under construction, as well as its eigenfrequencies, identified through the employment of a computer model.
The subject of the research represents the building of a universal pool under construction in Anapa. The general goal of this research is to identify the seismic stability of the building structure. An unbalance-type vibration machine was used in the course of the testing procedure. The machine was designed and manufactured at Moscow State University of Civil Engineering.
Identification of natural vibrations of building structures and verification of the identity of the computer model and the natural behaviour of the structure were to be completed to assess the required modes of operation of the vibration machine. Identification of full-scale dynamic characteristics was performed through the employment of the impulse method of vibration excitation.
Comparative analysis of experimental vibration frequencies and eigenfrequencies identified in the course of calculations based on different mathematical models demonstrates their similarity in terms of local shapes of vibrations, namely, in terms of buckling vibrations of an "annular" beam employed for the purpose of measurements taken in the course of the testing procedure. Frequency values identified in the course of testing and calculations vary from 4.5 to 19.8 Hz.
Calibration of the vibration machine represents another objective of the experiment. The experiment has demonstrated that the whole operating range of frequencies (2 to 15Hz) is to be employed in the course of testing procedures described above.

Road transport compared with rail, air and water transport is currently the most dangerous mode of transport. In recent years, more attention has been given to the issues of comfort and active safety of vehicles. Safety of the vehicle is a complex problem, the solution of which is primarily concerned with improvements aimed at enhancing active safety system driver - vehicle - road. One of the main vehicle performances significantly impacting road safety and the environment, is a high-speed mode. Active safety car driver includes the ability to assess the situation on the road and choose the safest mode of movement, as well as the possibility of the vehicle to implement the desired safe driving mode. Analyzing the causes of road traffic accidents submitted on the official websites of traffic police of the Perm region and Russia, it can be concluded that often carelessness and negligence of the driver is not the reason of an accident, but his inert perception, resulting in delayed response to rapidly changing traffic conditions. An average driver does not have the ability to instantly perceive suddenly appearing obstacles and quickly take measures to ensure the car’s handling and implementation of safe motion path. For this purpose we developed a modern technical means installed on a highway in the form of «vibrolane», with a driver fatigue monitoring system, which is aimed at preventing the driver wearied while driving behind the wheel from a possible departure to the oncoming lane or exit to the side of the road at driving on the hump. Thus, the proposed security system will reduce the number of accidents.
