  mechanical damping
The piezoelectric ultrasonic composite oscillator technique (PUCOT) has been used to measure the Young's modulus, E, the mechanical damping, Q-1, and the strain amplitude, ε, of a sintered silicon carbide containing pores (Hexoloy-SP).
      
Thermal cycling of the molybdenum- coated intermetallic between 600 °C and room temperature revealed a saturation increase in the modulus with a corresponding decrease in the mechanical damping.
      
An additional goal of the investigation was to determine if any correlation existed between the measured mechanical damping and the fracture toughness of the ductile iron materials; no correlation was found.
      
This article is a study of the mechanical damping of a series of well-characterized ductile iron materials (four separate materials) as a function of strain amplitude, temperature over the range of -100 °C to +100 °C, and magnetic field.
      
Proper design of such components requires a knowledge of the mechanical properties, including how energy is absorbed and dissipated (mechanical damping) by the test material.

The dynamic mechanical properties of the composite modified doublebase (CMDB), double-base (DB) and polyvinyl chloride (PVC) composite propellants were measured respectively with a Rheovibron viscoelastometer. The effects of three kinds of solid fillers[aluminium (A1), ammonium perchlorate (AP) and cyclotetraethylenetetranitramine (HMX)] and the different kinds and contents of plasticizers[triacetin(TA), ortho-dibutyl phthalate(DBP)and nitroglycerine(NG)]on the dynamic mechanical properties of the double-base...

The dynamic mechanical properties of the composite modified doublebase (CMDB), double-base (DB) and polyvinyl chloride (PVC) composite propellants were measured respectively with a Rheovibron viscoelastometer. The effects of three kinds of solid fillers[aluminium (A1), ammonium perchlorate (AP) and cyclotetraethylenetetranitramine (HMX)] and the different kinds and contents of plasticizers[triacetin(TA), ortho-dibutyl phthalate(DBP)and nitroglycerine(NG)]on the dynamic mechanical properties of the double-base binder were studied. The dynamic mechanical data and spectrums on these ingredients have been obtained at a fixed frequency(3Hz)and a broad range of temperature. At the same time, the impact strengths of the CMDB propellant, the double-base binder and the pvc propellant were also measured at a broad range of temperature. Experimental conclusions have been obtained that the dynamical mechanical properties of the CMDB propellant lie between the DB and PVC composite propellants and depend on its binder system, and that the CMDB propellant has the specific properties of both higher mechanical damping and a strong β relaxation at low temperature.

本文利用自动粘弹谱仪分别测定了改性双基(CMDB)推进剂、双基(DB)推进剂和聚氯乙烯(PVC)复合推进剂的动态力学性能。研究了三种固体填料[铝粉(A1)、高氯酸铵(AP)、奥克托金(HMX)]和增塑剂[三乙酸甘油酯(TA)、邻苯二甲酸二丁酯(DBP)、硝化甘油(NG)]的种类与含量对双基粘合剂的动态力学性能影响。文中给出了这些配方在频率为3Hz、宽广温度范围内的动态力学性能数据和图谱。本文还测定了CMDB推进剂、双基粘合剂和PVC推进剂在宽广温度范围内的冲击强度。本文认为CMDB推进剂的动态力学性能介于DB推进剂与PVC复合推进剂之间,并在使用温度范围内具有内耗较大、低温强β松弛的特点。
