Automotive air conditioner vibration test table

Abstract

The invention discloses an automotive air conditioner vibration test table. The test table mainly comprises a support and a test frame; the support is connected with a working table by a damping device; the working table is connected with the test frame by an elastic device; and the test table further comprises a control detection unit; the control detection unit comprises at least one vibration velocity sensor arranged on the test frame, a test program and a control device for controlling and displaying running state of an air blower, and a power and signal input device for the operation of the air blower of the air conditioner; the automotive air conditioner is connected with the test program through the signal and power input device, the test program controls the operation condition of the automotive air conditioner and is connected with a touch screen to display the vibration condition during the operation on the touch screen. The device of the invention uses the damping device to isolate vibration transmission between the test frame and the support, which prevents state of the test frame from interference by external vibration from the ground, and greatly improves detection accuracy. The test table also has good applicability.

Description

technical field [0001] The invention relates to the field of fixtures, in particular to a test bench applied to the vibration performance test of an automobile air conditioner. Background technique [0002] Adopting simple and reasonable tooling equipment is an economical and effective means to improve the efficiency of machining, testing and other operations. Therefore, technicians in various factories and mines are trying to continuously improve various special equipment. In the field of auto parts production, when HVAC (Heating, Ventilation and Air Conditioning, heating, ventilation and air conditioning engineering) is running, vibration will inevitably occur due to the power imbalance of the blower or negligence in assembly. This vibration has a direct impact on the comfort of the vehicle, so the vibration characteristic is a very important characteristic for the car air conditioner. Car air conditioners need to be tested for vibration performance before leaving the fac...

AI Technical Summary

Problems solved by technology

For the vibration test of the car air conditioner, there is no vibration test specifically for HVAC. Although this is beneficial to simulate the vibration of the car air conditioner in actual use, once the car air conditioner HVAC is installed on the vehicle and there is a vibration problem, it must be disassembled. Repair and replacement will be very troublesome

However, there is no vibration detection for the products of automotive air-conditioning HVAC manufacturers, so there are certain risks
