Summary: This paper studies the chassis frame of the upland gap self-propelled sprayer and designs a disconnected longitudinal beam frame with an X-shaped reinforcement beam. The static mechanical properties of the frame under bending, torsion, emergency braking, and emergency turning conditions are analyzed using a finite element method, and an optimization idea is proposed. The topology optimization method is then used to optimize the crossbeam and reinforcement beam positions, resulting in reductions in mass and maximum deformation of the frame under different conditions. The section width and thickness parameters of the frame are optimized through multi-objective driven optimization.

Summary: The prevalence of shared bikes in cities can have both positive and negative effects on local public transit services. It can lead to a decline in transit ridership as some patrons switch to cycling, but it can also benefit those who use bikes to access transit more efficiently. This study introduces a continuum approximation model for optimizing the hybrid design of shared-bike and transit services in a corridor with spatially heterogeneous demand patterns.

Summary: This paper introduces a four-wheel self-steering electric-driven chassis designed for handling complex agricultural terrains. Compared to conventional structures, this chassis achieves simultaneous steering and driving forward through coordinate differential speed control of drive motors, saving a set of dedicated servo steering systems and requiring less torque during steering. Experimental results demonstrate that the chassis has a smaller turning radius compared to conventional agricultural chassis.

Summary: A mountain bike carbon reinforced polymeric frame broke into two pieces while cycling over a grass meadow at a speed of 25 km/h, causing the rider to dislocate their shoulder. The study reveals the presence of multiple existing and spreading macroscopic defects, such as wrinkles, voids, and delaminations, resulting in low mechanical properties of the frame. Numerical dynamic simulations suggest that defect-resonance interaction is a contributing factor to frame weakening. The paper highlights the need for new scientific and technological advancements in designing carbon fiber reinforced plastic frames for mountain bikes, emphasizing the importance of eliminating pre-existing defects and proposing flaw tolerant solutions inspired by nature.

Summary: This paper proposes a design of hydrostatic chassis drive system for a large plant protection machine in order to meet the working performance and requirements. The combination of a hydraulic drive system and shunt valve is used to realize the anti-slip rotation function and improve the driving stability. The study calculates and selects the parameters of the main hydraulic components, models and simulates the hydraulic drive system using AMESim software. The test results show that the hydraulic chassis of the plant protection machine designed in this study has good driving stability and can effectively reduce the slip rate.
