Design method of mechanical parts for automobile inspection tools

       The design method of mechanical parts for automobile inspection tools can be classified differently from different angles. At present, the more popular classification method is to refer to the design method used in the past as a conventional (or traditional) design method, which has been developed in recent decades. The design method that comes up is called the modern design method. Modern design methods are developing rapidly. Currently common: computer-aided design (cAD), optimized design (oD), reliability design (RD), tribology design (1D), design methodology design (coffee), parametric design (PD), intelligent design (m), etc. The emergence of these new design methods has caused great changes in the field of mechanical design of automobile inspection tools. The mechanical design of automobile inspection tools is more scientific and complete. This section focuses on the general design methods used in this book.

 

    The conventional design method of the automobile inspection tool mechanical jujube can be roughly classified into the following three types.

    1. Theoretical design

    According to the existing design theory and experimental data, the design of mechanical parts of automobile inspection tools is called theoretical design.

for:

    (1) Design calculation, which directly determines the main parameters and dimensions of the part from the theoretical design formula;

    (2) Check calculation. After preliminarily determining the main parameters and dimensions of the part by experience and some simple methods,

On the check formula of the check formula.

    Design calculations are mostly used for parts that can be designed with simple mechanical models; check calculations are often used for complex structures.

Parts with complex stress distributions but capable of strength calculation or stiffness calculation.

    2. Empirical design

    Based on the empirical formulas and data that have been derived from the existing design and use practices of certain types of components, or by analogy

The design carried out is called experience design. The empirical design is zero for those that have little change in the use requirements and that have a typical shape.

Pieces are very effective design methods. For example, the various components of the radiator, the frame, and the transmission parts, etc.

    Type 3.6 experimental design

    For some important parts and components with large size, complicated structure, special working conditions and difficult to calculate theoretically,

To improve the design quality, a model experimental design method can be used. That is, the preliminary design of the zero, component or machine into a small model

Or a small-sized prototype, through the experiment of the model or prototype, assess its performance, and then modify the original preliminary design according to the experimental results

To make it gradually perfect. This design process is called model experiment design. This design method is time consuming and expensive, so it is only used

In a particularly important design.
