Adjusting the damping by adding or adjusting shock absorbers can limit the vibration amplitude at the time of resonance.

The result The body vibration was reduced to by 50 percent compared to the original design, and the body radiated noise was reduced by three decibels. This process played a critical role in the development of a new washing machine model.

The eccentricity of the rotating drum produces centrifugal force, resulting in forced vibration of the drum. According to the Nielsen research on requirements for washing machines in China, 51 percent of all interviewed consumers regard vibrational noise as one of the biggest problems that washing machine manufacturers must solve.

One of the most important initiatives was the introduction of LMS Test. This technical team has been used to solve key problems, such as the reduction of vibrational noise. This is also reflected in statistical data.

The cost of this method is low, but it does not really eliminate resonance, so the noise reduction result is limited. Lab signature tool, when the rotating speed was above 1, rpm. Adjusting the exciting frequency limiting the speed of rotation can avoid the integral frequency of the body structure.

Most manufacturers use a combination of the second and third methods.

The six points at which such components are connected with the body are named as coupling points, and the body right side center is named as the target point.

Case analysis of swan continuous improvement of these requirements is one of the biggest challenges faced by the manufacturers. Clean, healthy and environmentally friendly are the main product characteristics of washing machines. Lab transfer path analysis TPAthe Little Swan team quantified the contribution of each transfer route to the body right side vibration.

Due to the damping provided by shock absorbers, the amplitude of this forced vibration is very small. By using the report creation template, engineers can quickly generate reports after completing the test and then compare the vibration and noise reduction results of different design plans. Adjusting the body rigidity or changing the connecting device to change the body rigidity produces the vibration and noise reduction results, but requires mold and process changes that increase the manufacturing costs.

Manufacturers of name-brand washing machines now focus on the positioning of their products and set quality requirements that correspond to their brand positioning. At this stage, the ease-of-use of the LMS solution — from operation of the data acquisition equipment to the user interface of the analysis software — makes it much easier to compare plans.

Over the past few years, China has changed its birth regulations and implemented the two-child policy. However, this method affects the basic cleaning and dewatering functions of washing machines, so it is not a desirable method.

Both the total number of complaints and the number of noise-related complaints for this product are much lower than the industry average. Engineering challenges The vibrational noise that consumers complain about is reflected mainly in the body, but the actual vibration energy comes from the rotating component, the drum.

The associated quality requirements include improved cleaning performance, reduced wear, pollution prevention, reduced water and energy consumption, reduced noise and others.

At the same time, only the connecting structure of the suspending spring required reinforcement and the entire body did not need to be altered, so that the effects of the changes on the process were limited.

This was the direct result of improving the spring reinforcing element. Utilizing the powerful test and data processing capabilities of this solution, the team set up a standard test and a complete optimization design process, especially for the vibration noise of washing machines.

The vibration frequency is the same as the rotational speed. The new washing machine was well received in the marketplace. The analysis showed that the contributions of the hanging points of the suspension springs are always the greatest at different rotational speeds, so the team concluded that reinforcing the connecting structures of the springs could effectively increase the body rigidity and achieve the best vibration noise reduction results.

However, when the rotational speed is close to the integral frequency of the body structure, the amplitude of the forced vibration increases, causing a lot of energy to be consumed by the vibration of the body.

In a drum washing machine, the drum is connected to the body by the following components: In this process, the LMS Test. The excitation forces and transmission functions are compared at different rotational speeds and different coupling points.

However, each method, whether combined or not, requires setting up conditions and analyzing test data to obtain the resonant frequency and to verify it after each proposed improvement plan. Three classic methods can solve this problem.CASE STUDY SWAN REHABILATION COMPANY: A GREAT SUCCESS STORY Question 1 Capital budgeting can be defined as making an investment decision involving fixed assets.

On the contrary, the CASE ANALYSIS OF SWAN’S ICE ARENA 3 revenue would go down in the off-season. So the revenue can be easily affected by external environment. The information above illustrates the weakness of Swan’s Ice Arena.

The analysis of the problem enabled the Little Swan R&D team to focus on improving the reinforcement of the springs and quickly develop several preliminary design plans. At this stage, the ease-of-use of the LMS solution – from operation of the data acquisition equipment to the user interface of the analysis software – makes it much easier.
