Research On Model Design Of Dust Suppression Spray Truck Based On Perceptual Engineering

As an inherent product in the city,the dust suppression sprayer is an inherent product in the city,which not only represents the image of the city but also shows its cultural value.Therefore,the "appearance" shape of the dust suppression sprayer is particularly important in the design.However,the design of existing dust suppression spray car styling fails to consider the perceptual needs of consumer groups and lacks market competitiveness,and there is still a lack of systematic scientific analysis and calculation from the internal function of the product to the appearance and modeling.So,it is the general trend to improve users’ satisfaction with existing products and improve the innovation of the dust suppression spray car styling design.This subject aims to analyze the corresponding relationship between the perceptual image and the design elements of the dust suppression spray car model based on the perceptual needs of the target users.In order to improve users’ perceptual demand for dust suppression sprayer.It is worthwhile to achieve the best performance of modeling,and quantify the perceptual demand into tangible design elements to guide the innovative design of dust suppression and spray molding.First,based on emotional design concept to explain concepts and research methods Kansei Engineering and dust suppression spray of car design.Analyzing and summarizing the important influencing factors and design requirements of the dust suppression spray car styling from the user’s perceptual needs;Then,through a questionnaire survey,collect perceptual vocabulary samples that meet the user’s needs and summarize and obtain the perceptual demand factors of the dust suppression spray vehicle,perform multi-dimensional scale analysis and establish a perceptual image space,and deconstruct the representative samples collected in modeling morphology.Under the guidance of the quantitative theory class I,multiple regression analysis is carried out,and the feasibility of the corresponding relationship is verified by the T test,and how to convert the user’s perceptual needs into dust suppression spray car styling design elements and guide the design practice.Finally,the fuzzy comprehensive evaluation is used to construct the evaluation index body and judgment matrix of the dust suppression sprayer model evaluation.According to the analytic hierarchy process algorithm to calculate the modeling weight of the dust suppression sprayer and sort and position it.Presenting the researchers’ qualitative evaluation of the dust suppression spray truck in a quantitative form.In the modeling design of dust suppression spray vehicle,the concept of perceptual design is integrated.The mapping relationship between image modeling and perceptual cognition is defined.The method of correlation analysis of perceptual needs is transformed.The invisible perceptual image words are transformed into tangible design elements,which can effectively guide the innovative design of dust suppression spray trucks,and provide reference for the product modeling research method of the industry.This study is expected to play a positive role in alleviating the current situation of urban pollution and improving the city’s cultural image.
