Shaoxing Dongyun Machinery Co., Ltd. has launched a heavyweight 3.5T automotive chassis road simulator, boosting the localization and upgrading of automotive testing equipment

Recently, Shaoxing Dongyun Machinery Co., Ltd. officially launched its self-developed YQJ-3500DP 3.5T automotive chassis road simulator. This product is specifically designed for scenarios such as automotive chassis system testing, suspension noise diagnosis, and steering performance evaluation, and can be widely applied in 4S shops, maintenance service centers, commercial vehicle fleets, and automotive testing institutions.

Currently, the global automotive road simulation system market is experiencing sustained growth. The global market size was estimated to be approximately $1.558 billion in 2025, and it is expected to reach $2.583 billion by 2032, with a compound annual growth rate (CAGR) of 7.6%. Meanwhile, the State Administration for Market Regulation is comprehensively promoting the localization verification and evaluation of inspection and testing instruments and equipment. The tire-coupled road simulation tester is listed as one of the key "bottleneck" high-end general-purpose equipment to be tackled. Against this backdrop, Shaoxing Dongyun Machinery Co., Ltd. has actively responded to the domestic substitution strategy and launched a chassis road simulator with completely independent intellectual property rights.

This product utilizes motor frequency conversion drive technology, allowing for freely adjustable speed and precise simulation of various real-world road conditions. Equipped with a 360° rotating steering wheel, the device can comprehensively test the flexibility and reliability of the vehicle's steering system. The top V-shaped structural design ensures structural stability and compatibility with tires of various sizes. Each device comes standard with four height-adjustable feet, allowing for height adjustment to accommodate different vehicle models at any time; the bottom is equipped with heavy-duty casters, facilitating angle adjustment and overall machine movement.

In terms of technical specifications, the product model is YQJ-3500DP, with a rated load capacity of 3500KG, a range of motion from 0-20mm, a motion frequency from 0-200 times/minute, a frequency adjustment range from 0-50Hz, a motor power of 2.2kW, and dimensions of 700×720×1040mm. The equipment is also equipped with a rear wheel safety fixing bracket (500×720×1000mm), and the power supply specifications can be customized according to customer requirements.

Shaoxing Dongyun Machinery Co., Ltd., as a professional manufacturer of automotive lifts and testing equipment, has always been committed to providing high-quality maintenance and testing solutions for the automotive aftermarket. The launch of the 3.5T automotive chassis road simulator further enriches the company's product portfolio. In the future, the company will continue to increase R&D investment, promote the localization process of automotive testing equipment, and contribute to the high-quality development of China's automotive industry.
