Research on Mass Ratio in Secondary Vibration Isolation

Hao Wu, Min Chen
The secondary vibration isolation may be used to abate sound transmission in solid in the application of damping and noise reduction treatment engineering, which can have an ideal effect. The secondary vibration isolation system has a natural low frequency so it can isolate low frequency vibration. The...

Study on the Sound Quality Objective Evaluation of High Speed Train's Door Closing Sound

Zongcai Liu, Zhaojin Sun, Shaoqing Liu
Test the high speed train's door closing sound under different close pressure and then use the linear sound pressure level(SPL), A weight sound pressure level, psychoacoustic parameters of sound quality and specific loundness to analyse the sound. The results are indicated as follows: the frequence of...

The Comparison and Analysis of Humidity Environment between Floor and Ceiling Radiant Cooling Systems that Combined with Displacement Ventilation

Kai Sun, Chuan-hui Zhou
At present, the study on the temperature fields of floor radiant cooling system and ceiling radiant cooling system based on displacement ventilation is more, but for the humidity field research of the two systems is insufficient. There is a thermal stratification in the temperature field of both kinds...

The effect of gap of building on indoor flow field and thermal environment

Hao Li, Zhijun Zou, Fei Wang
In summer and in winter, the outdoor air will flow in room through the gap of building. Which will influence the indoor flow field and thermal environment and cause draft, the human in room will feel uncomfortable. This paper use the method of numerical simulation to research the effect of outdoor air...

The Understanding of Temperature Cognition and Thermal Sensation

Jiaolin Wang, Wei Xu
Relying on the thermosenstors scattering in the skin, people are capable of detecting the thermal stimuli to protect themselves from the damage of hazardous environmental factors. Temperature sensitive sensors can be divided into two classes: innocuous thermosensors (warm or cool) and noxious thermonociceptors...
