Friction property of HDPP modified with talc under the dry friction condition Chen Nanchun1,2,a, Deng Aiping1, Cheng Peng1, Wang Wei1 1 College of Materials Science and Engineering, Guilin University of Technology, Guilin 541004, China 2 Key Laboratory of Nonferrous and new Materials Processing Technology, ministry of Education, Guilin University of Technology, Guilin 541004, China aE-mail:cnc@glite.edu.cn Keywords: modify; talc; HDPP; friction properties.
The Wear test method was based on friction materials and friction conditions.
As the talcs filled and modified HDPP, the materials appeared thermoplastic.

Considering the advantages and disadvantages of two kinds of structure optimize the combination of sound absorption materials, adding in the perforated resonance basis, considering the combination of sound absorption material and cavity and thickness of the sound absorbing material for absorbing materials, at least to sound absorption effect is the best.
In anechoic chamber is provided with a sound barrier on different absorption materials, different top shapes of insertion loss measurement.
In the test of the same kind of structure by using different sound barrier sound absorbing materials were tested to obtain data, sound absorption properties of different absorption materials; insertion loss by replacing the top structure to test different, get the curves of different structure influence on insertion loss.

Axis of the planet given to different materials to comparative simulation and comprehensive analysis, given the best materials of planetary shaft should be selected, improved the reliability of planetary axis under poor conditions.
The selected materials of planetary shaft should be with high yield strength and good rigidity to meet the required strength in severe shock.
Through the analysis of simulation, it won't generate larger influence for the force situation of shell and planetary when the planet shaft materials changed in the prototype model.
