With the development of science and technology and even the market demand, the improvement of the performance of diesel engine’s noise, vibration and harshness (NVH) has become a symbol of the inner product quality[1,2].
The finite element models require detailed geometric and material data of the engine components, as well loading data defined by engine combustion forces.

At the same time, dress material needs to insulate electricity, to prevent the occurrence of shorted and circuit breaker.
In the production material selection of the reception robot, you can choose paraffin wax and silicone material, which have higher simulation of human body skin.
So, silicone is the most suitable material of skin simulation.
If a robot only has imitated the skin material, and has far disparity from the experienced contact height of the human.

The basic principle that solar thermal uses is to gather solar radiation energy with a collector, then turn it into thermal energy for utilization by interaction with materials.
Existing problems of solar energy industry development Imbalance on solar energy technique development and backward in photovoltaic generation technique Utilization of solar thermal energy, relatively maturely developed in our country, is in leading position on technique and market of same kind worldwide, but utilization of solar thermal energy mainly concentrates in traditional water heater aspect and makes no breakthroughs in technique fields of solar thermal generation, polymer materials and combination between solar energy and architecture, strong in industry but weak on scale compared with developed countries.
Basic research, material research, application research, industrialization research, market development and cultivation and construction funds can’t be guaranteed constantly in long term.
