Ecological transport systems must be provided with efficient vibration damping systems for the comfort and safety of the user. This paper analyses a shock absorption system that can be used in an individual three-wheeled transport vehicle. The vehicle has a complex structure, with an equal size of the front and rear wheels. This uniformity of dimensions between the rear and front wheels makes it easier to travel on rough terrain and manoeuvre in a folded shape. The tricycle allows aggregation with different agricultural equipment and can be used in small farms, greenhouses, solariums, meadows, orchards, etc. In this paper we simulate several models of absorption systems with different construction parameters. The strength of the system and the efficiency of shock absorption were taken into account. The best result of the simulation test for absorption systems will be the comparison with the actual physical model used by the electric vehicle.

In the current work, we study the propagation of perturbations through networks of springs which are spatially distributed on a plane. We show that the topological properties of the network are related to the dissipation of energy within the system. By varying the rewiring parameter of the graph, and thus going from a regular to a random structure, we obtain a lower energy output, due to the fact that the initial (linear) perturbation is transformed into oscillations around each node. The results obtained are related to the transmission of information through a complex structure with potential applications to the design of more efficient damping systems.

Merauke Regency is one of the largest rice producers in Papua Province with a total production of 344,192.32 tons in 2020, a harvested area of 61,584 ha and a rice productivity of 5.59 tons/ha. Agricultural development in Merauke Regency is supported by the availability of agricultural land and the modernization of agricultural equipment. The post-harvest process is the final phase that is key to success, so it must be handled properly to achieve maximum results once the post-harvest rice begins with the rice harvest. The rice harvest must be supported by a robust transport vehicle in wet and muddy fields. Vehicles with caterpillar drive wheels are compatible because the ground pressure is lower. The design of the rice transport vehicle selects the track wheel type as the drive wheel so that it can be used on wet and muddy surfaces. The vehicle chassis is designed for the transport of 1000-1500 kg of rice. The construction and analysis are simulated with Autodesk Inventor software; the Chasis model is analyzed for strength using the finite element method.

Liquid shock absorbing system as the primary one, although it can solve the shock absorbing problem, there has been a crash or impact occurs instantaneously when the apparent tilt steering and comfort very poor phenomenon. To this end, a new study of nitrogen gas shock absorber fluid control body height at rated load automatically within the body to adjust to the optimal height designed to improve the car's shock absorber damping effect, making the car more shock absorption system safe and comfortable, with a more stable operational.
