The Mathematical Model

The influence of mounting motors in wheels’ hubs and flexibility of the twist beam rear suspension on their dynamics and strength is presented in the paper. The international roughness indicator (IRI) is applied to assess the overcoming of road unevenness. This indicator is a combination of a shape of the road unevenness and of overcoming velocity. The movement of a wheel’s axis during obstacles overcoming is described. For the needs of the dynamics analysis, the mathematical model of the rear suspension system with embedded motors is developed using the MSC.Adams-ANSYS interface. The discrete model of the twist beam is prepared in the ANSYS software, which is used in the next step to construct the dynamics model of the rear suspension system using the MSC.Adams program. The vertical components of displacement and acceleration of the wheel’s centre, forces in the suspension’s springs and dampers, as well as forces in the joints are analyzed. The analysis of the suspension beam’s stress during the road unevenness overcoming is also carried out.

This paper discusses impact of changes in the load size and distribution in passenger cars on geometry of the suspension and steering systems. It was found to have a major impact on the road safety. The research was carried out with the four most popular suspension system designs used in modern passenger cars, i.e. multi-link suspension on both front and rear axles, only on the front axle, only on the rear axle and a simple suspension design for both front and rear axles. Eight load variants were used for the tests. Changes in the following wheel geometry parameters were identified: toe-in and camber angles of all the wheels and castors for the front wheels. The numerical relationships were determined between the load distribution and sizes and changes in suspension and steering systems in passenger cars. It was found that cars with multi-link suspension in both front and rear axles adapt best to changes in weight and load distribution.

The Impact

Owing to the tamping mechanism of paving machines, the shocks towards flatiron-box are produced by compound motion of tamping beam. This significantly influences the road paving quality. In this paper, the dynamics model of double-tamper mechanism is established and the vibration process is simulated by the numerical analysis software—Matlab. Through the analysis of double-tamper mechanism, we can get the impact regularity of the vibrating beam inertia force and moment of inertia as a result of the vibration frequency and amplitude. It provides a reference for the design of double-tamper mechanism for asphalt paver and the adjustment of construction parameters.

Torsion Bar

The conventional design and manufacturing of rear suspension system in All terrain Vehicles were  Double wishbone, Semi trailing arm, Mcpherson strut and torsion bar but to overcome the adverse effects such as  wheel wobbling, Uncontrolled Toe and power losses from transmission. So by introducing a H-arm suspension system at the rear end of the vehicle can improve the performance of the vehicle by keeping it stable and able to sustain all the incoming loads from the ground and provides a comfortable drive and by maintaining a constant Toe which will improve the transmission. The primary objective of the suspension system in the ATV is to maximise the contact between the tires and the road surface, providing good handling and steering stability, evenly distributed weight throughout the vehicle and ensuring riders safety also comfort by absorbing the shocks from the terrain. Ansys solver is used for analysis, lotus shark used for the simulation and the modelling is done by using Solidworks 19. Fabrication of the system was done according to the Design values, run- virtual compliance test is performed for checking the vehicle dynamics.

The main objective of the Suspension of a vehicle is to maximize the contact between the vehicle tires and the road surface, provide steering stability and provide safe vehicle control in all conditions, evenly support the weight of the vehicle, transfer the loads to springs, and guaranteeing the comfort of the driver by absorbing and dampening shock. This paper discusses the kinematic design of a double a-arm Suspension system for an FSAE Vehicle. The hardpoint’s location can be determined using this procedure to simulate motion in any kinematic simulation software. Here, Optimum Kinematics is used as kinematic simulation software, and the results are verified using Msc Adams simulation. The method illustrated deals with the basics of Kinematics which helps to predict the characteristics of the Suspension even before simulating it in the kinematic simulation software.

Abstract: A wheel assembly is an integral part of a vehicle’s design that connects the wheel to the suspension system and transfers pressure from the road to the suspension system. It also holds the brake system and facilitates steering. Power transmission is also addressed in the powertrain department. We describe the process and simulation that result in the hub, upright, and differential mounting of a formula student car and the size of the sprocket for maximum acceleration in this report. As a result of the work done on this project, the resulting car has improved acceleration, is easy and reliable to assemble, and has fewer breakdowns than the previous model. The report includes all the calculations that support the simulations and a validating statement about the bearing selection.

Two Wheeler

Two wheelers like motorbikes and scooters are one of the major transports in India. In major cities and towns, it is most common private transport as it is fast and easy approach to the destination. But the prolonged drive in the two-wheeler leads to the potential health hazard and musco-skeletal disorder due to continuous exposure to the vibration caused during the ride and force transmitted to the vehicle body due to road irregularities. It is a challenge of automobile engineers to design a promising suspension system to overcome the risk of ride comfort during continuous driving. In this research, two-wheeler suspension system is modelled with a condition of bump and valley in a wavy road. The road surface is assumed to be wavy and the response of new suspension spring with different materials (stainless steel, tungsten and polymeric) along with viscous damper is analyzed and compared. By this analysis, it will be proposed to industry to modify the suspension system to improve its efficiency and reduce force transmitted to the human body to improve the ride comfort
