本发明具体实施提供了多种用于高转速环境下用于高通量测试的原位加热系模式,为开展不同温度、不同转速条件下材料性能测试提供新的实验条件。The specific implementation of the present invention provides a variety of in-situ heating system modes for high-throughput testing in high-speed environments, and provides new experimental conditions for conducting material performance tests at different temperatures and different speeds.

其中,本发明的加热模式包括但不限于如下几种情况:Wherein, the heating mode of the present invention includes but not limited to the following situations:

加热模式一:高转速下对测试试样1.1的标矩段1.1.2实施均温加热模式,图10。Heating mode 1: Implement uniform temperature heating mode on the standard moment section 1.1.2 of the test sample 1.1 at high speed, as shown in Figure 10.

实验材料类型相同,实验过程中标矩段1.1.2与上感应线圈2.1和下感应线圈2.5之间的距离h保持相同,且加热功率和加热频率在t时间内保持不变,给标矩段1.1.2施加一个恒定且均匀的温度场。The type of experimental material is the same, the distance h between the standard moment section 1.1.2 and the upper induction coil 2.1 and the lower induction coil 2.5 remains the same during the experiment, and the heating power and heating frequency remain unchanged within t time, the standard moment section 1.1 .2 Apply a constant and uniform temperature field.

加热模式二:高转速下对测试试样1.1的标矩段1.1.2实施周期性变化的交变温加热模式,图11。Heating mode 2: Under the high rotation speed, the alternating temperature heating mode is implemented to periodically change the standard moment section 1.1.2 of the test sample 1.1, as shown in Fig. 11 .

实验材料类型相同,实验过程中标矩段1.1.2与上感应线圈2.1和下感应线圈2.5之间的距离h保持相同,加热频率不变,但在t时间内使加热功率周期性变化,给标矩段1.1.2在t1时间内施加T1、在t2时间内施加T2的交变温度场。The experimental material type is the same, the distance h between the standard moment section 1.1.2 and the upper induction coil 2.1 and the lower induction coil 2.5 remains the same during the experiment, the heating frequency is constant, but the heating power is periodically changed within the time t, and the standard Section 1.1.2 is an alternating temperature field in which T1 is applied during t1 and T2 is applied within t2.

Since the distance from the arc-shaped standard moment section 1.1.2 to the induction coil 2.1 and the lower induction coil 2.5 changes continuously, according to the principle of induction heating, under the same power and frequency conditions, the heating temperature of the sample is inversely proportional to the distance from the induction coil to the induction coil. This implements a constant temperature gradient for the standard moment section 1.1.2 of the test specimen 1.1.
