The collision progress between piston and the guide sleeve at 2m/ssimulated by LS-DYNA software shows that the maximum stress is 674MPa which locates at at the edge of the liquid inlet hole of guide sleeve, and the maximum stress on interface is less than 400MPa, both of them area lower than theyield strength of materials, so the guide sleeve is of shock resistance.
The strength of the seal materials requires the pressure in cylinder should not be too high, and the peak should be under 40MPa.
Vice versa, when one-sided clearance is 0.1mm, the buffering terminal speed will decrease to under 0.35m/s, and the peak pressure is within the permitted range of seal materials.

Synthesis of Single-Crystalline Plate-shaped K0.5Na0.5NbO3 Particles by Multi-step Molten Salt Method Zhi Liu, Yue-Ming Lia, Zong-Yang Shen, Zhu-Mei Wang School of Materials Science and Engineering, Jiangxi Key Laboratory of Advanced Ceramic Materials, Jingdezhen Ceramic Institute, Jingdezhen 333403, China a lym6329@yahoo.com.cn Keywords: Piezoelectric ceramics; Multi-step molten salt method; Perovskite Abstract.
First, precursor particles K4Nb6O17 (K4N6) with layer-structure was synthesized at 1050 °C in molten KCl-salt (MMSM-1) by starting materials of Nb2O5 and K2CO3.
Preparation of KNN from K4N6 precursors: Using K4N6, potassium carbonate (K2CO3, SCRC), potassium chloride (KCl, SCRC) and sodium chloride (NaCl, SCRC) as raw materials, KNN was converted from K4N6 by MSM according to the following Eq. 2.
Meanwhile, both KCl and NaCl were used as raw materials and molten salts in this reaction, and the total weight of KCl and NaCl was equal to K4N6 and K2CO3 [13].
