The follow-up hydraulic muffler can make the natural frequency of the muffler equal to systematic pulsation frequency in time by changing the section area of the quality chamber so as to achieve the best attenuation effect. In this paper, a spring-damp regulator is installed on the basis of the hydraulic muffler, and the static and dynamic characteristics of the follow-up hydraulic muffler are analyzed by measuring the rotational speed of the pump with the sensor. The results show that the hydraulic muffler based on the spring-damp regulator can effectively attenuate the pulsation.

Regarding software as a tool of social production, this article was used to explore it‘s development process—the process of software development also is the process of making tools.

Very complicated as the cycloid wheel movement appears, tridimensional software Solid Works is applied to outer planetary cycloid wheel parts modeling and dynamic simulation with the outcome meeting the prospective design requirements. Therefore, we conclude that tridimensional modeling will be applicable for mechanical designing with great significance. In response to increasingly complicated product designing, the roles of the tridimensional modeling approach will be brought into fuller play. In pin-cycloid gearing, due to the specially curved and differential gear surface, the gearing accuracy and service life of the pin-cycloid are both affected. To get a smooth solution to the problem of the tridimensional surface shaping, priority shall be given to precise drawing of the gears profile curve [.
