Decision-making regarding the application of any new structure at the design stage requires in practice that it should be compared with the existing one by many indicators. A special feature of the new design of hydropneumatic suspension is the existence of movable connections (screw and splined) as parts of the hydropneumatic element. The presence of structural friction in movable connections requires, in particular, an assessment of the impact of this friction on the process of oscillations when moving through crossed terrain based on comparative analysis. The comprehensive estimate chosen for comparison includes operational properties in terms of ergonomics (smooth movement) and adhesion to the support surface (effort in the contact of wheels with the support surface). The results of a theoretical study involving a vehicle with parameters (weight, dimensions) close to armored personnel carriers BTR70, BTR80, but with hydropneumatic suspensions, demonstrated that when driving on crossed terrain with speeds up to 65 km/h there is a significant reserve in terms of ergonomics. Regardless of the presence (absence) of structural friction, at friction coefficients of up to 0.085. When moving on the surface with large irregularities, the reserve for the maximum allowable (3 g) acceleration in a driver seat is 4.708 times (there is no structural friction) and 3.768 times (structural friction is present). When moving on the surface with small irregularities, the reserve for the maximum permissible (0.5 g) acceleration in a driver seat is 2.093 times (there is no structural friction) and 2.616 times (structural friction is present). Under the most dangerous modes of movement (at the highest speeds) when driving over small irregularities, the presence of structural friction has a positive effect both in terms of ergonomics and stability. Thus, when driving at a speed of 65.679 km/h, the minimum clutch margin is 1.4 times greater, and the acceleration is 1.249 times smaller

For today’s composite materials have many advantages over steel materials. The composite materials take the main part in modern automobile constructions. Suspension system is the main automobile part. Components of suspension system are made of metal. Therefor suspension system have a high weight that have a negative effect for all of vehicle especially for vehicle dynamics and stability properties. The main part of suspension system is a spring element. Coil springs are the most widely used spring type for independent wheel suspension for trucks and passengers vehicles. Using composite springs can less vehicle weight especially less unspring masses. It is one of the main features of composite materials. Another feature is viscoelastic properties and hysteresis effect. That can be give excellent noise and vibration properties for vehicles.

“…10 proposed an electro-hydraulic semi-active shock absorber to obtain suspension kinetic energy and developed an electro-hydraulic suspension test-rig to test the performance of the shock absorber, whose peak exciting force was come up to 8500 N. To test the performance of single suspension components and single support suspension units, Novikov et al. 11 developed an electro-hydraulic servo suspension system test-rig, with the maximum excitation frequency of 50 Hz and the maximum exciting force of 50 kN. For high speed tracked vehicles with a heavy load, when the performance of the suspension system is tested, the exciting frequency of the test-rig varied in the range at 0.1–50 Hz, the exciting displacement of the test-rig varied in the range at 3–50 mm, and the exciting force of the test-rig is not less than 50 kN.…”

The suspension test-rig is restricted by the compound swing motion of the load wheel in a high-speed tracked vehicle, and cannot test the damping performance for the suspension system of the high-speed tracked vehicle with the track. A vibration damping testing mechanism using vertical linkage to decouple the compound swing motion of the load wheel is proposed for suspension performance testing with the track. Using Hertz elastic contact theory to solve the stiffness coefficient between load wheel and excitation wheel, a virtual prototype model for vibration damping test mechanism with vertical linkage is established in ADAMS. Correctness of the virtual prototype model is verified by experiment. The motion decoupling ability of the vibration damping testing mechanism is verified by simulation. The dynamic characteristics for each pair of guide and slider in vibration damping testing mechanism are analyzed under the condition of maximum excitation force and displacement, and the selection criteria of slider and guide contained in the motion pair components are acquired. The mechanism decouples the compound swing motion of the load wheel successfully, and can make suspension system performance testing in high-precision for the high-speed tracked vehicle with track realized, playing an important role in parameters design and performance optimization for the high-speed tracked vehicle.
