In the market, the thermoelectric device are mostly flat plate, and the solder overflow in the process of Bi2Te3 and copper welding is called wall-hanging phenomenon (WHP). This phenomenon mostly occurs in the production line and is inevitable, but it is seldom studied by scholars. In this paper, COMSOL software is used to simulate and analyze the wallhanging phenomenon, and the structure is optimized for this phenomenon. The simulation results show that when the load resistance is small, the wall-hanging phenomenon can improve the output power and conversion efficiency, which is beneficial, when the load resistance is large, the wall-hanging phenomenon will reduce the conversion efficiency, which is harmful. The smaller the size factor is, the less the impact of wall-hanging on the conversion efficiency of the thermoelectric parts. Therefore, when the load resistance value is large, the harm of wall-hanging can be reduced by reducing the size factor.

In this paper, a Fractional-Order Global Sliding Mode Control (FOGSMC) scheme based on a neural network with approximation property (NNO) is mainly focused on study the Thermal-Structural Test (TST) system. Since the nonlinear dynamic system of the thermal-structure test with quartz lamp is susceptible to external interference and parameter variation, a novel FOGSMC system is designed based on improved fractional order global terminal sliding surface to acquire the desired trajectory, and real time estimation of system disturbance using neural network observer with Gaussian Function, meanwhile, the fractional-order global terminal sliding mode surface based on fractional-order function can effectively weaken the chattering phenomenon of the integer order, simulation studies show the effectiveness of the proposed method.

According to the characteristics of cabbage harvesting machinery, SOLIDWORKS and simulation software are used to carry out structural design and simulation analysis of its cutting device. The physical characteristics and planting status of Chinese cabbage and its rhizome were studied, and the cutting device meeting the actual harvest requirements was designed. Theoretical analysis was used to analyze the arrangement and force of the cutting knives, and a reasonable layout of the double disc knives was designed to ensure that the cabbage rhizomes could be effectively clamped and cut off, and the cutting qualification rate was improved. The virtual cutting motion simulation test of the disc rhizome cutter was carried out with ADAMS software. The movement of the single point on the knife is analyzed, and the movement law diagram of the displacement and trajectory of the single point of the knife is obtained. It is determined that the rotation of the blade can well cover the travel area to prevent missed cuts and reduce power loss. Carry out orthogonal test on the cutting device, determine the influence degree of each factor on the cutting force, and obtain the optimal parameter combination.

Aiming at the problems of insufficient utilization of cooling capacity and low ice making efficiency in the ice making process of small household ice maker, a new type of water tank was designed by calculating and analyzing the cooling capacity in the ice making process of ice maker. Simulate the ice making process with software AnsysFluent, compare the ice production of ice maker with new and original water tank in the same time, and carry out experimental verification. The simulation result shows that 75.68% of the cooling capacity is wasted in the original water tank, and only 28.85% in the new water tank when ice making time is 9 mins. At the same time, the cold energy consumption in the new water tank is 43.34% lower than that of the original water tank, and the ice production is increased by 65.22%. The experiment result shows that the ice production of ice maker with the new water tank is increased by more than 75% when ice making time is between 8 and 10 mins; the ice production of ice maker with the new water tank is increased by more than 35% when ice making time is between 11 and 12 mins, and the optimization effect is obvious.

In recent years, domestic commercial vehicles have developed rapidly, and many series of products have been developed from light, medium to heavy. However, the vibration and noise problems of the cab of commercial vehicles during driving still fall far short of the requirements expected by customers. In order to improve the comfort of commercial vehicle cab during driving, the mounting system and vibration isolation and noise reduction system of commercial vehicle cab are designed. The cab mounting structure is an active electromagnetic mounting structure. Through the blind source separation algorithm built in the cab mounting ECU, the impact of vibration on the cab during driving can be quickly eliminated. The vibration isolation and noise reduction system adopts double-layer sound insulating glass and ANC active noise reduction system to minimize the noise transmitted to the cab. Through the self-designed active electromagnetic mounting structure and the vibration isolation and noise reduction system composed of double-layer sound insulating glass and ANC active noise reduction system, the comfort of commercial vehicles during driving is improved, which meets the expectations of customers.
