制作了由两种不同相变温度的 SMA 和 SMP 组成的 SMC 带，并研究了弯曲驱动时的三向（往复）运动和恢复力。所得结果可总结如下。 1)根据SMA带和SMP带的特性，在加热和冷却过程中实现三向弯曲运动。 2) 恢复力在加热过程中先减小后增大，在冷却过程中减小。通过所提出的模型粗略估计了恢复力。 3）结构简单的多功能SMCs用于三维执行器的开发和应用备受期待。
The SMC belt composed of two kinds of SMAs with different phase transformation temperatures and SMP, was fabricated and the three-way (reciprocating) movement and recovery force in bending actuation were investigated. The results obtained can be summarized as follows. 1) The three-way bending movement was achived during heating and cooling, based on the characteristics of the SMA tapes and the SMP tape. 2) The recovery force decreased at first and increased thereafter during heating and decreased during cooling. The recovery force was roughly estimated by the proposed model. 3) The development and application of multi-functional SMCs with simple structure for three-dimensional actuators are highly expected.
