The creation of an electromagnetic shock absorber system is necessary taking into account such parameters of the vehicle and operating conditions as the quality of the roadway, the grades, and the weight and size of the vehicle. A mathematical simulation model of the vehicle was developed to determine energy indicators in various road sections. The MATLAB Simulink programming environment was chosen to create the most practical and functional simulation model. A number of experiments were carried out using various parameters of the vehicle, types of roadways and driving cycles. Simulation results allow obtaining basic characteristics of electromagnetic damper of the selected vehicle, on the basis of which a linear electromagnetic damper shock absorber will be calculated. System energy efficiency was determined when using a vehicle on roads having a different road surface evenness index.

Electromagnetic Shock Absorber

Electromagnetic harvesters need to be designed with a mechanism to amplify the coil relative velocity to ensure compact size and lower weight. This paper discusses a novel technique to use fluid link for velocity amplification in an electromagnetic shock absorber. Incorporation of the fluid amplification significantly improves harvested power, without affecting the system dynamics. Numerical modelling and experimentation of a prototype shock absorber comprising of high energy rare earth magnets have been presented. Peak coil voltage of 0.60–24.2 V was recorded during experimentation on the prototype. Experimental and simulation results validate that incorporation of the fluid amplification link improves the harvested electric power by 9702%. Comprehensive design procedure for better harvesting efficiency and vibration isolation has been discussed. Lastly incorporation of the shock absorber in McPherson strut suspension is illustrated. The real size version will be able to harvest peak power of 18–227 W for the suspension velocities of 0.15–0.4 m/s.

The main objective of the study was to develop a simulation model for the operation of the T-214 CYKLOP grapple loader using the MATLAB package. The created model allowed assessment of the behaviour of the real object in the operating conditions under variable loads and in the system overload. The simulation of the boom operation was carried out in four combinations: (1) at power take-off speed = 1000 rpm without load and (2) at 1000 kg load, (4) at power take-off speed = 540 rpm without load and (4) at 1000 kg load. The results show that the system works properly. The correct functioning of the system is evidenced by the fact that changes in force and acceleration occur on both pistons when only one of the cylinders is operating (the cylinder at rest acts as a shock absorber for the forces resulting from the inertia of the arms and the load). Apart from the increased forces on the pistons of the hydraulic cylinders, the additional load resulted in a slight reduction in acceleration values and an increase in the time needed to change the arm tilt angles.
