dc.description.abstractotherIn some modes of movement of the aircraft on the ground, the vibrations of the wheels of its chassis may occur. These oscillations are called shimmies, due to the unstable process of straight rolling of the wheels. Shimmy wheels are associated with the possibility of their angular oscillations relative to the vertical axis. Shimmy type fluctuations can occur for both steered and unmanaged chassis wheels. Rotation of steered and unmanaged wheels relative to the vertical axis at the shim is due to the elastic twisting of the landing gear. The design of the airplane chassis must ensure that the wheel rolling process is stable in all possible modes of movement of the airplane on the surface. The choice of the parameters of the chassis support, which ensures the absence of shimme, is achieved by the calculation of the wheels on the shimme, as well as laboratory tests on the shimm of full-scale installations of the chassis. The maximum allowable parameters for the installation of the chassis are the values at which, based on the results of the calculation and tests, a stable rolling of the wheel in all modes of operation of the aircraft is created with a certain margin. The need for inputs of stock from shimmy wheels on the parameters due to errors in the calculation and testing of wheels on the shimm, as well as the variation of the characteristics of the chassis supports. The stability of orienting, steered and unmanaged wheels of an airplane from a shimmy is determined by the combination of a large number of values characterizing the properties of the landing gear and the conditions of movement of the airplane. The impact of changing many values of us rolling resistance is difficult depending on other parameters and is not fully taken into account when designing racks. When initially selecting the chassis parameters, it is important to take into account only the most pronounced and slightly changing when other characteristics change the relationship between the parameters, which compliance creates a stable rolling of the wheels. Parameters that can significantly affect wheel shimmy stability include radius and mass, lateral stiffness of the tire, lateral stiffness of the chassis and its torsional stiffness, wheel removal, shimmy damping resistance and ground speed. The effect of changing the parameters on the rolling resistance of the wheels is usually considered in the relationship between any two parameters that correspond to the boundary of the wheel shimmy at fixed values of other parameters.uk
