The article is devoted to the analysis of braking force influence on mountain bike suspension by creating (arranging) dynamic experiment simulation. To obtain required information, value of braking force was measured. This was followed by creating dynamic model with SOLIDWORKS CAD and SOLIDWORKS Motion addition. Bike suspension was tested under different braking modes, measuring sprang and unsprang mass hesitation parameters and ground reaction force, which are sought for suspension specification. The obtained results and data in the form of graphs may become an incentive for developing, analysing and maintaining the transport in the field of mountain bike engineering.

The possibility of manufacturing wearable electronics elements, for example, strain gauges or antennas of RFID tags, by applying or locally applying a layer of electrically conductive graphite polymer compositions to the surface of a fabric (knitwear) using printing technologies has been studied. The pliable tape-shaped prints can be used as strain gauges to be placed on human clothing or robot arms. The tensile limits of sensors made on fibrous substrates of various structures using graphite dispersions in the form of powders and aerosols have been established. The strain sensitivity coefficients of the sensors are determined. The advantage of glueless spraying of a liquid composition of graphite in the form of an aerosol onto fibrous materials is shown.

A structural mathematical model of physical effects in the form of a weighted graph is considered. The basis for classifying the database and creating trends of physical effects is the concept of invariant. The transfer matrix based on the dimensions of the input and output of the effect is an invariant. A dimensional simulation of multidimensional physical effects is considered and a numerical estimation of the obtained models is proposed. The estimation is used to synthesize the operating physical principle of information and energy circuits.

The article is devoted to the topic of analysing main exploitation properties of mountain bike suspension from the point of creating 3D dynamic exploitation simulation. For the purposes of the research, a special dynamic simulation was created using SOLIDWORKS software and SOLIDWORKS Motion tool. Two types of bike suspension were tested on the dynamic analysis stand measuring sprang and unsprang mass hesitation parameters, which are demanded in suspension specification. The obtained specific simulation results in the form of graphs and data tables may become an incentive for continuous developments and analyses in the area of constructing.

The article presents a synthesis technique for controlling the stabilization of a reverse pendulum, which does not require repeated code generation when making changes to the parameters of the control object. The problem of developing a feedback control system for a reverse pendulum controlled by a gyrodine is considered. The main tool for developing a control system is a combination of a real-time control system based on STM32 and an external computer based on ROS.

This article presented the results of the development and calculation of the plant supply system for an underwater dock station using a three-phase float wave power plant of the inverted construction. The results of the completed work allow to solve the problem of creating the plant supply system for underwater dock stations and resident underwater robots, as well as speed up their implementation in practice.
